5）After AIR CAL., set the instruments so that it can monitor objective gas, and press PUMP key. The color of the display reverses while the pump is operating.

Indication while the pump

operating is not the result of monitoring. 6) Press PUMP key and stop the pump after indication become stable, and read the indication. The indication under the condition that the pump and sample gas flow have stopped is the monitoring result.

Caution Press AIR CAL key after confirming there is engh fresh air in the chamber. Otherwise, correct measurement cannot be performed.

* Note If the [AIR] is selected as the base gas, the indication shows [0.00vol%] when the AIR CAL key is pressed. However, If the [O2] is selected as the base gas, the indication does not show 0.00vol%, but other vaulues determined based on the conbination of the measuring gas and the base gas. This is caused by sampling the gas which is not on target. (In this case, it is air.) Do not think it broken. Once the instrument samples the target gas, it shows a correct reading. For further information, refer to the spec pages.

Caution FI-21 performs best when both Gas Chamber and Reference Chamber are at the atmospheric pressure (101.3kPa). While the measuring gas is being sampled, the pressure in the Gas Chamber becomes slightly different from the atmospheric pressure, and the analyzer does not show the correct reading. Read the indication after the gas flow stops.

* Note FI-21 measures the gas best when both Gas Chamber and Reference Chamber are at 101.3kPa. If precise measurement is required, perform the pressure correction by the following method. 101.3 [kPa] × (Reading − Air Cal. Value) ＋ Air Cal Value Pressure Correction ＝ Pressure at measurement [kPa]

The Meanings and the Requried Treatments Battery voltage is too low to perform the measurement. Replace the batteries. Contamination of the optic interferometer sensor is too serious to perform the measurement. Replace the sensor or have it repaired. The brightness is too low to perform the measurement. Replace the sensor or have it repaired. The setup data saved in the setting mode has an error. Confirm the setup data in the setting mode, and set the data again.

2-6. AIR CAL. CAUTION If the temperature inside of the sensor has changed over ± 10℃ from the last time the AIR CAL was performed, [CAUTION/ CHECK AIR CAL] is displayed in order to protect fromzero drifting. ([Measuring Gas/ Base Gas] and [AIR CAL] are displayed consecutively.

every one second. If the [CAUTION/ CHECK AIR CAL]: is displayed, perform the AIR CAL based on the procedure below: AIR CAL. Procedure 1. Press the PUMP key and let it sample some fresh air. 2. When the indication becomes stable, stop the pump with PUMP key and prese the AIR CAL key.

Caution Before pressing the AIR CAL key, let the instrument sample enough fresh air. (ideally for 2 minutes. ) Otherwise, correct measurement cannot be performed.

Caution Whenever measurement starts, confirm if the AIR CAL value is displayed after fresh air is sampled enough. If the AIR CAL. Value is not indicated (or even if [AIR CAL CAUTION] is not displayed), perfrom the AIR CAL procedures by correct method.

INS-1451E

2-7. Affection on Measurement from Pressure

CAUTION The pressure in the Gas Chamber becomes different from the atmospheric pressure whiling sampling the gas. As a result, the indication is not accurate. Or, if an instant pressure change occurs in the Gas Chamber or the Reference Chamber, the indication might go wrong. (If these symptoms occurs, perform the AIR CAL right away.) Therefore, take care about the following points: > Do not plug the GAS IN or GAS OUT while gas is feeding. > Keep the pressure of GAS IN, GAS OUT, and REF. OUT equal to the atmospheric pressure when the indication is read. > Read the indication after the gas flow stops.

CAUTION When concentration change occurs suddenly on the FI-21, correct reading cannot indicate. Absorption tube is not only for removing the humidity, but also for stabilizing the temperature of the sampling gas. Therefore, equip an absorption tube on the GAS IN whenever the measurement is performed.

- 12 -

INS-1451E

An example of measurement when the pressure of the sampling point is higher than the atmospheric pressure: Make an inlet (a) as the drawing below. Open and shut the stop valve to feed the gas to the instrument, instead of turning the pump on and off. Read the indication after shutting the valve off and the gas flow totally stops. Flow rate at Inlet (a) should be 300 to 400mL. GAS OUT should be at the atmospheric pressure and the REF. OUT should face with fresh air.

4. Maintenance 4-1. Replacing the Batteries

Warning >

All the C size Alkaline batteries used in the instrument should be same kind.

> Replace the 4 of the batteries at the same time.

1) Confirm that the power is off. 2) Take out the instrument from the carrying case. 3) Take off the battery cover under the bottom by turning the screw with a coin. 4) Take out the old batteries and put the new ones caring the polarities. 5) When the replacement is done, put the battery cover on the bottom by the opposite procedures. 4-2.

Confirming the Sensitivities

It is recommended that the sensitivity of the instrument be confirmed periodically (at least once a year) to assume the correct operation. The procedures for the sensitivity confirmation are as follows: If any problem is found, or If you would like to have it calibrated, please contact any of our agents. 1) Select “DESFLURANE in AIR 0-20vol%” and go into the measuring mode. 2) Perform the AIR CAL as it is done for the usual measurements. 3) Feed some pure CO2 (at 99.999% +) to the instrument. 4) Perform the Air Correction by the following calculation: Result of the Air Correction ［vol％］＝

101.3［kPa ］ Atmospheric Press at Measurement ［kPa］

× Indication Value［vol％］

5）If the result of the Air Correction is 15.66±0.47［vol％］, the sensitivity is normal. 4-3. Daily Check 1) Is there any damage on switches, lamps, display or body? 2) Confirmation of battery voltage. 3) Do you see “CAUTION …” or “ ERROR…” during the operation?

7. Caution on Usage The following caution items must be followed to maintain the performance/ safety of the instrument.

Danger > Specification of this instrument is based on a non-explosion structure. Do not use it in a place specified as a hazardous area. > Make any solutions for exhaust gas emitted from GAS OUT, to avoid harmful gas from emission. (e.g. Connecting a sampling bag to GAS OUT.) > Just in case of leaking from the instrument itself, wearing a mask and gloves is recommended.

Warning > The instrument shows incorrect indication when it samples a high concentration gas over the full scale. > Use the batteries based on the specifications. > Use the specified AC adaptor if necessary.

Caution > Do not use this instrument close to other apparatus that generates a strong noise. It may affect the wave form of the power source. If the AC adaptor is applied, do not use the same power source as other apparatus that generates a strong noise. > Use the power source based on the specifications. > Do not operate the instrument in a place which has a reaction heat such as infrared emitted from high temperature. Or, Avoid a place which has a direct sunbeam that makes the instrument over 35C. > Interference Gas: The gases which are neither the target gas nor base gas. If there is any interference gas in the measuring gas, the reading goes wrong. Do not measure the gas which contains interference gas. > Let GAS OUT and REF. OUT expose to the air, in order to equal the pressure inside to the atmospheric pressure. > Whenever this instrument operates, keep it in a carrying case and connect the absorption tube.
