Do not remove tab during detection.
If TAB is removed during detection, the detection is interrupted, and that
cycle cannot be restarted with a new TAB. The error message TAB is
displayed. The old TAB must be discarded and replaced with a new one
before a new cycle is started.
•
When the detection range is changed for a new cycle, be sure to exhaust
the inside gas by pre-sample drawing from the instrument (see Section
1.7 Preliminary Sample Draw Mode) to flush out any residual gas
concentrations inside the unit. If high-density gas remains inside the FP-
30 then it may affect the next gas detection cycle.
•
Do not suck water or oil into the instrument since this will cause pump and
instrument damage.
•
When detecting gas, confirm that the pump is working by listening to the
humming sound of the pump or confirming that the pump is sucking. If the
pump is not sucking, no gas detection will occur.
•
Do not block the gas outlet, or else an incorrect gas reading may result.
NOTE
Only one type of detection TAB is used in the FP-30 & FP-40, but the TAB may be used
for three different detection ranges. For the FP-30, select the TAB No. according to the
desired detection range. The FP-40 can only be used for one detection range.
