1.Caution in operation
For this function maintenance and safety, it is required to keep the following warning and caution.
WARNING
・Do not modify or change circuit and structure etc. When modify or changed, the
original function may not be maintained.
・Do not mix up metals and flammable foreign substance inside at TAB
replacement time. When it is used as it stands, it will be a cause for the
malfunction, electric shock and fire.
CAUTION
・Do not drop or throw.
As this is a fine instrument, the function could not be maintained by strong
shock.
・Arrange that water could not be splashed directly.
As this is not drip-proof structure, it will be a cause for trouble due to the
splashing of water.
・Do not use the walkie-talkie nearby.
When receive the electric noise, it may affect the reading of gas detection and
will be a cause to damage the instrument.
・When ambient air or temperature is changed, it may affect the gas detection.
・When condensed, it is impossible to make normal measurement.
・When scrap this monitor after long use, and as this is not used with harmful
materials, handle this as the general industrial scrap(Non-flammable goods).
・For detection TAB, handle it as general industrial scrap(Non-inflammable) as far
as any special requirement is not made.

３－２． Start-up operation
When pressing ＯＮ／ＯＦＦswitch for 2 sec on、the power gets on and self-diagnosis starts.
Then, this gets to a waiting condition.
The program until it gets to the waiting condition shall be as follows;
（１）When not attach the detectionＴＡＢ,
Press ＯＮ／ＯＦＦswitch for 2 seconds.
BATT：Ｅ －－－｜－－ Ｆ （Shows the battery capacity）
Approx 5 sec
STAND BY OK （Detection is standby）
Approx 5 sec
SET ＴＡＢ （Waiting condition）
（２）When the detectionＴＡＢ is attached,
Press ＯＮ／ＯＦＦswitch for 2 seconds
BATT：Ｅ －－－｜－－ Ｆ （Shows the battery capacity）
Approx 5 sec
SELF-DIAGNOSIS （Self-diagnosis：Sensor check）
Approx 5 sec
STAND-BY OK （Detection is standby.）
Approx 5 sec
SELECT ＴＡＢ Ｎｏ ▲▼ （Select the detectionＴＡＢ）
CAUTION
Do not remove the detection ＴＡＢ during self-diagnosis(sensor check).
The self-diagnosis cannot be carried out correctly and the message of sensor fail
shall be shown.
＊ NOTE
When turn on power with the detectionＴＡＢ loaded in, the optical sensor is
checked by the self-diagnostic function. Make the sensor check at its suitable
time.
For sensor check, use new detection TAB. When use the used up TAB or
much deteriorated TAB which passed for a long time after unpacking, the
correct reading could not be carried out and there will be the possibility that
sensor fail message could be shown.

３－３． How to mount the detection ＴＡＢ .
For handling the detectionＴＡＢ, see the item４－２
①Open the detectionＴＡＢ cover.
②After releasing finger used for mounting theＴＡＢ, close the cover slowly.
◯
3Press the center of detection TAB cover by finger.
CAUTION
・ When close the detectionＴＡＢ cover, close it slowly so that the finger
cannot be sandwiched.
If release the finger lifting the detectionＴＡＢ cover suddenly, it may bring the
damage of cover or injury. It is required to pay attention for it.
・ When mount the detectionＴＡＢ, it is required to pay attention that water
drops or dust cannot be mixed up in from the mounting port.
Lift up to this way.

DANGER
The sucked gas may be the case of oxygen deficiency or toxic gas. Do not
breathe in the gas exhausted from the gas outlet absolutely.
When senses such, exhaust it to the place where to judge the safety area
CAUTION
・ Do not removeＴＡＢ during detection.
The detection is interrupted on the way and the detachment message of
ＴＡＢ is displayed. The detection re-starts.
Once theＴＡＢ is removed, the gas detection is interrupted even though it is
re-mounted.
・ When the detection gas is changed, be sure to exhaust the inside gas by
pre-sample drawing from the instrument because the high density gas may
remains inside of gas detector and remain inside and it may affect the next
gas detection.(See the ３－５）
・ Do not have water or oil sucked into instrument.
If it should be sucked, the internal pump and sensor may become impossible
to use.
・ When detect gas, check that pump is working or not.
This can be checked by the roaring sound of pump or sucking condition of gas
inlet. When pump remains stopping, this cannot make gas detection.
・ Do not block the gas outlet. It cannot make correct gas detection.
＊ NOTE
The suction time is different by the kind of detectionＴＡＢ each.
When make the detection for formaldehyde based on ＷＨＯ Room Environment
Standard（0.08 ppm）, use the detectionＴＡＢ No.008（0～0.4 ppm）and make
the average measurement for 30 minutes.
＊NOTE
FP-30 provides only one kind of TAB, but two measuring ranges. Select the TAB No.
according to the measuring range.
Measuring range Measuring time TAB No.
0～0.4 ppm 30 min. 008
0～1 ppm 15 min. 009
