Digi-Sense Thermometer Operating Model 39643-00 Instructions

Digi-Sense Thermometer Operating Instructions The 39643-00 thermometer is a non-contact infrared thermometer. Simply aim the thermometer at the target and press the ‘Meas. key’ to display the surface temperature.

Laser Information:

By partially pressing the ‘Meas. key’, the device will begin to measure the temperature of the target. When the ‘Meas. key’ is completely depressed, the laser will operate.

CAUTION! 1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY RESULT. 2. USE EXTREME CAUTION WHEN OPERATING THE LASER. 3. NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES. 4. KEEP OUT OF REACH OF ALL CHILDREN.

EMISSIVITY RANGE

The infrared thermometer is supplied with a default emissivity of 0.95. The emissivity can be changed from 0.05 (5E) to 1.00 (100E). Changes should only be carried out by experienced personnel. To change the emissivity, first turn the instrument on by pressing the ‘Meas. key’, then press the ‘Mode key’ five times for emissivity function. The 95E will flash on the LCD screen, then press the ‘Meas. key’ to adjust the emissivity value, press the ‘Mode key’ again to exit the set up screen. For information relating to the emissivity of specific materials, please contact the nearest retailer. Note: non-contact infrared thermometers are not recommended for use in measuring the temperature of shiny or polished metals.

LCD ERROR MESSAGES

The 39643-00 incorporates visual diagnostic messages as follows:

MINIMUM OR MAXIMUM MODE

To utilize the minimum or maximum mode, first turn the instrument on by pressing the ‘Meas. key’, then press the ‘Mode key’ once for minimum or twice for maximum function. The ‘MIN’ or ‘MAX’ icon will flash, then press the ‘Meas. key’ to confirm the minimum or maximum mode. The meter will display the minimum or maximum reading only.

LOCK MODE

When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with a CR2032 lithium cell. The battery is located under the twist cover at the rear of the meter. Please note: It is important to turn the instrument off before replacing the battery otherwise the meter may malfunction. Dispose of used battery properly and keep away from children.

STORAGE & CLEANING

The sensor lens is the most delicate part of the meter. The lens should be kept clean at all times, care should be taken when cleaning the lens using only a soft cloth or cotton swab with water or medical alcohol, allowing the lens to fully dry before using the meter, do not submerge any part of the meter. The meter should be stored at room temperature between -4 to 149°F.

SPECIFICATION 「

」

「

」

‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the range of the instrument, ‘Hi’ when higher than 482°F (250°C) and ‘Lo’ when lower than -27°F (-33°C).

‘Er2’ is displayed when the meter is exposed to rapid changes in the ambient temperature. ‘Er3’ is displayed 」 when the ambient temperature of the meter EXCEEDS 32°F (0°C) OR 122°F (+50°C). In both cases you should allow plenty of time (minimum 30 minutes) for the meter to 」 stabilize to the working/room temperature.

「

「

For all other error messages it is necessary to reset the meter. To reset the meter, turn the instrument off, remove the battery and wait for a minimum of one minute, reinsert 」 the battery and turn on. If the error message remains please contact the Service Department for further assistance.

°F OR °C MODE

To change from ‘°F’ to ‘°C’ or from ‘°C’ to ‘°F’, first turn the instrument on by pressing the ‘Meas. key’, then press the ‘Mode key’ four times, the ‘°C’ or ‘°F’ symbol will flash, press the ‘Meas. key’ to change to scale.

BATTERIES

The 39643-00 has two separate batteries. The battery closer to the side of the laser beam output is for laser operation only. The other battery is designated for temperature measurements. The meter can still measure temperature properly, even without the laser battery. The meter incorporates visual low battery indication (for the lower battery) as follows:

Measurement Range –67 to 482°F (-55 to 250°C) Operating Range 32 to 122°F (0 to 50°C) Accuracy, +/-1° F (+/-0.6°C) (Tobj=15-35°C,Tamb=25°C) Full Range Accuracy +/-2% of reading or +/-3.6° F (2°C) (whichever is greater) Resolution (-9.9~199.9°C) 0.1°F / 0.1°C (switchable) Response Time (90%) 1 second Distance:Spot 8:1 optics ratio Emissivity Range 0.05~1 Step.01 Battery Life Typ. 40hr, min 30hr (auto power off after 15 seconds) Battery CR2032 (for Laser, 2pcs required) Dimensions .7 x 1.4 x 2.6” (18.0 x 36.6 x 67.8mm) Weight 63 grams including batteries

EMC/RFI

Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.

GUARANTED

The 39643-00 is guaranteed for a period of one year from the date of purchase against mechanical and electrical manufacturing defects. There are no user serviceable parts inside the instrument. Any attempted repair by unauthorized persons voids the warranty.

The lock mode is particularly useful for continuous monitoring of temperatures. To utilize the LOCK mode, first turn the instrument on by pressing the ‘Meas. key’, then press the ‘Mode key’ three times for the lock mode function. The lock icon will flash, then press the ‘Meas. key’ to confirm the lock mode. The meter will continuously display the temperature for up to 60 minutes or until the ‘Meas. key’ is pressed again.

‘Battery OK’: measurements are possible

‘Battery Low’: battery needs to be replaced, measurements are possible

‘Battery Exhausted’: measurements are not possible
