Explanation of Temperature Control Terms Temperature Calibration

Accuracy We do not provide, claim or assure any form of accuracy. Accuracy is defined as "the ability of a measurement to match the actual value of the quantity being measured". For accuracy we recommend using a calibrated reference probe at the actual set point temperature and where necessary, adjust the set point accordingly. Sensitivity For an explanation of sensitivity consider a unstirred digital water bath, the PID temperature control system measures and displays the actual temperature of the water and then compares it with the ‘set point’ temperature. It automatically calculates and adjusts the required quantity of heat into the bath to make the measured temperature equal to the set temperature. As with any process there is a time delay between measuring the temperature and the heat entering the water, which causes minor fluctuations in the temperature of the bath. Heat is also distributed in an unstirred bath by convection and conduction and there are heat losses from the surface of the liquid which can cause temperature losses. These losses and heat distribution produce small fluctuations in temperature across the water in the bath. These small temperature fluctuations at any one point are defined as “sensitivity” and vary between an upper and lower limit, however occasionally a larger variation can be observed. Sensitivity as stated in DIN 58966 is the temperature difference between the upper and lower temperature level over 100 cycles after removing the largest 25% of readings. We determine sensitivity by recording the actual upper and lower temperatures of the bath using temperature loggers and is stated as plus or minus one half of the measured value. Uniformity Uniformity is calculated by measuring the temperature in opposing ends of the water bath and is the difference between the mean temperatures at these two points and stated as plus or minus half this value.

Explanation of “Clifton Optimized Control” “Adaptive tune” provides instant control from start up and automatically adjusts PID values with actual temperature readings until it achieves set temperature. These adjusting PID values determine heat-up rate, the load and volume of liquid producing negligible overshoot. All this happens automatically and requires no setting giving you peace of mind. “Clifton Optimization Control” is a new feature, which uses SMART temperature control technology to allow for liquid and or volume variation, external environmental variables and including your work to refine control at set temperature, enhancing the range. The new “Clifton Optimization Control” is best used to fine-tune its PID values by optimizing any potential difference between set point and actual temperature readings: Unstable condition

Set point e.g. 60.0 C

+ C

Returns to "Adaptive Control" using new PID values

"Adaptive Control"

"Opt" selected

"Optimized" PID values @ 60C

Examples of “unstable conditions” where optimisation is useful include: • • •

Liquid level changes: low to high liquid levels, smaller volumes of water needing faster reacting control in comparison with larger liquid volumes. Changing liquid type: from water to oils, and oil to water. Oils suffer with hot and cold layers in the liquid, until natural convection occurs at higher temperatures unlike water where convection is immediate. External environmental conditions in the room where bath is working or circulating water baths, where piped liquid is affected by external temperatures.

Clifton Water baths can adjust to these “unstable conditions” updating the PID values, relearning how to control your process, at a specific temperature to give optimal control.

How to Operate the Optimization Function Clifton ‘Optimised Control’ fine-tunes the PID values by optimising any potential difference between the set point and the actual bath liquid temperature. This can be activated when necessary and forces the controller to update the PID values allowing it to cope with changing liquid types e.g. water vs. oil, changing volumes and environmental factors. The bath is calibrated for use with water. When changing from water to oil we recommend that the optimisation feature is used. This is because water and oil have different thermal properties. To start:1.

Press FUNCTION button until “OPT” appears on the display alternating with “ON.A”.

2.

Press either up or down arrow to select “OFF”.

3.

Press FUNCTION button to confirm.

4.

Press FUNCTION button until OPT appears on the screen.

5.

Press up arrow to select “ON”.

6.

Press FUNCTION button to confirm.

7.

When the “opt” and temperature value is alternately displayed the unit is self-adjusting. When only the temperature is displayed optimisation is complete. Occasionally during the “optimization” process the audible over/under temperature alarm sounds and indicator illuminates, this is quite normal; ignore this warning and allow the bath to continue to desired temperature.

8.

When only the set temperature is displayed, the optimisation process is complete.

To cancel this process at any time press FUNCTION button until “OPT” is displayed. Press up or down arrow to select “OFF”. Press FUNCTION button to confirm.

Under Temperature Alarm - Automatically Set The under temperature alarm is automatically set 4°C below either 'Set Point 1' or 'Set Point 2'. When in alarm condition the ‘over and under temperature ‘ alarm indicator illuminates and actual bath temperature is shown. Please note if an accessory DC1-300 dip cooler is fitted cooling will continue. Once water temperature has risen above alarm setting then indicator clears and actual bath temperature is displayed. Always investigate the cause of the Under Temperature Alarm. Over Temperature Alarm - Automatically Set The over temperature alarm is automatically set 4°C above either 'Set Point 1' or 'Set Point 2'. When in alarm condition the ‘over and under temperature ‘ alarm indicator illuminates and actual bath temperature is shown. All heating/cooling is switched off. Please note if an accessory DC1-300 dip cooler is fitted cooling will continue. Once water temperature has fallen below alarm setting then indicator clears and actual bath temperature is displayed. When in alarm condition the motor and heater are switched off on NE4-P and NE4-HT. NE4-D models motor remains on but heater is switched off. Always investigate the cause of the Over Temperature Alarm. Safety Experiment Protector - HT Range only To set the safety device: 1. Safety device knob (located on the rear) is turned fully clockwise. 2. Set the temperature on the temperature controller at which temperature you require the device to operate, using instructions for set point 1 (see page 6). Allow the liquid to reach this temperature and settle. 3. Slowly turn the knob back anticlockwise until it clicks. 4. Adjust the temperature on the temperature controller to the actual required operatingtemperature - value less than set in 2 above. When in alarm condition heater is switched off and the motor remains on. Low Liquid Level Float Switch - all models - “FIL” meassge displayed The unit features a low liquid level float switch. This ensures heating will be switched off if the liquid level falls below the recommended level. The motor and heater are switched off in this instance. A “FIL” message appears on the display indicating Low liquid level. Refill the tank for heating and stirring to resume - caution when refilling as hot elements can spit and create scalding steam. Periodical Check The low liquid level float switch should be checked periodically by lowering the level of liquid in the tank. The unit should display “FIL” message on temperature display. In the event of the unit not displaying this message please contact our service department at the address shown above. The Safety Experiement Protector featured on the NE4-HT should be routinely checked for correct operation where used. Follow set up instructions as described above.

Cleaning General Important - please follow these instructions to avoid possible damage to the unit, otherwise affecting its performance and warranty. Always disconnect the product from the electrical supply before cleaning. Cleaning External Painted Surfaces featuring “Anti-bacterial Paint Finish” The water bath should be cleaned at regular intervals wiping external surfaces with a cloth or sponge soaked in warm soapy water with a mild detergent. All surfaces should be cleaned using a soft cloth or sponge. Do not under any circumstances use strong solvents or solutions containi ng Chlorinated Hydocarbons, Esters, Ketones or abrasive cleaners or polish on the paint finish otherwise it damages the built in anti-bacterial properties. All painted surfaces on Clifton range products features an “Anti-bacterial paint finish” identified with this authenticating logo on the unit. This “Anti-bacterial paint finish” inhibits the growth of bacteria. It has been tested by independent specialist test houses such as the Law Laboratories (in the UK) using internationally recognized test methods and proven to be effective versus a wide range of bacteria species including Escherichia coli and Staphylococcus aureus (MRSA). We recognise hygienic coatings are part of a controlled approach to a cleaner working environment. Within its formulation an active ingredient with proven anti-bacterial properties is bound into the paint finish. The efficacy of the paint finish applied to the Clifton range is maintained over its lifetime, as the anti-bacterial agent is integral within the paint. In a laboratory environment it makes this one less source of contamination, contributing to essential clean working practices. A benefit of such a paint finish can lead to a reduction in cleaning schedules because surfaces are more protected and improves protection between cleaning. Unlike detergents “Anti-bacterial paint finish” does not offer an instantaneous action, but is intended for long-term general protection against bacterial growth. Moisture on the painted surface is necessary for the bacterium to absorb the agent and be affected by it. The coating is therefore less active in very dry conditions, but dependent upon relative humidity, moisture in the atmosphere maintains activity. Areas where moisture is trapped are also areas that normally are difficult to clean and where bacteria proliferate but these areas are most active for the anti-bacterial coating improving the defence against bacterial growth. Cleaning the Stainless Steel Tank The stainless steel crevice free tank with smooth corners should provide years of valuable service and is resistant to chloride containing solutions it is however important to avoid high concentrations of halogens - especially chloride. With such a high quality and resistant tank it may show symptoms of these halogens as rust, which are deposits from external sources in the water supply. We recommend always empty the bath of liquid after use and wipe out the internal faces of the tank with a non-abrasive cloth and allow to dry. Any deposits can be removed with nitric acid (10%) on a cloth. WEAR PROTECTIVE EQUIPMENT! It is also recommended to use an accessory lid to prevent contaminates landing in bath liquids.

Fitting Accessories for NE4 Series GRP Gable Lids Position the lid over the bath and lower into place. The lids are designed to fit snugly so that condensate runs into the bath. Stainless Steel Gable Lids Position the lid over the bath and lower into place. These lids have bo drip points, provide full working height across the bath when fitted and have a ventilation gap. Stainless Steel Flat Lids Position the lid over the bath and lower into place. Stainless Steel Raised Shelves The raised shelf provides a reduced liquid depth for shallow vessels in NE4 series water baths. With recommended minimum water level in NE4 range of 70mm with this in place it will provide a working depth of 5mm or 35mm. Stainless Steel Test Tube Racks Place the loaded test tube rack into the bath on top of either the stainless steel perforated shelf or the raised shelf. Immersion Cooler This refrigeration cooler has no temperature control, as it is designed to be used in conjunction with a stirred or circulating water bath, where its immersion coil is specially designed to fit rear access hole behind the Thermostirrer/Thermocirculator without sacrificing the working area. The immersion cooler runs continuously providing counter cooling with bath providing temperature control. Heat Transfer Fluid Use as a ‘neat’ liquid solution for best results. Thermometer Clip This can be positioned anywhere on the perimeter of the bath by cliping over the edge. The thermometer then lies flush with the top edge of the bath to prevent accidental damage. Draining Syphon Allows the easy and quick emptying of any water bath. Water temperature must be below 45°C before emptying can commence. Mounting Bracket This Mounting Bracket is designed to fit the NE4 series Clifton Thermostirrers for mounting on any number of vessels or tanks. Maximum tank thickness for the Bracket = 30mm.Thumb wheel adjuster secures the Bracket and Thermostirrer to tank. Polyproylene Spheres Place on top of the water/oil to provide a floating lid reducing evaporation and insulating the bath reducing heat losses.
