4 How to Operate

4-1-3. Power-on
Turn the power switch of the gas monitor from OFF (
side) to ON (l side).
The gas monitor is powered on and brought into detection state.
NOTE
After power-on, tape feed is always executed. Turning ON/OFF the power unnecessarily with the tape
attached can shorten the tape life.
NOTE
If a high concentration gas is present after turning on the power with the detection tape attached, alarm
will be triggered even before the gas monitor is brought into detection state. However, because the gas
monitor is not in detection state yet, the concentration display cannot provide accurate information.
4-1-4. Attaching gas detection tape cassette
Attach the gas detection tape cassette suitable for the detectable gas.
Check that the tape model is appropriate for the detectable gas.
For details, see "6-3 How to replace gas detection tape cassette". After a gas detection tape cassette is
attached (cassette tray is closed), the gas monitor enters detection state in approximately one minute.
NOTE
After the tape cassette is attached, tape feed is always executed once. Removing/attaching the tape
unnecessarily can shorten the tape life.
NOTE
If a high concentration gas is present immediately after attaching the tape cassette, alarm will be triggered
even before the gas monitor is brought into detection state. However, because the gas monitor is not in
detection state yet, the concentration display cannot provide accurate information.
4-1-5. Flow rate
Because the suction flow rate of the gas monitor is automatically adjusted by the flow rate control function,
the flow rate, in principle, does not need to be controlled. If the flow rate goes out of the specified flow rate
for some reasons, the flow lamp turns from green to orange, but the flow rate will be adjusted automatically.
CAUTION
If the auto-adjustment cannot be performed (due to tube clogging, leak, etc.), the message
indicating dropped flow rate "FAIL=FLOW" will be displayed. In this case, identify the cause and
take appropriate actions.
