OPERATION AND USE
12.
At any time the operator may save the readings on the display by
pressing the ZERO/SAVE BUTTON (C). This will save all readings for
download at a later time. Log size is factory set to store 6 logs, but
can be increased up to 100 logs. The most recent save is first during
download. An optional Auto log software of extended memory can store
up to 1,600 records. (Consult factory for details.)
13.
Following Federal, State, Municipal and/or Company procedures
move to the areas where gas readings are suspected or must be tested.
Use necessary accessories to draw samples from areas not accessible
with the instrument itself, such as confined spaces or flues. During
sampling, the respective readings may change. Audible and visual
alarms will activate when the preset limits are reached.
14.
When equipped with the percent volume sensor, if the instrument
encounters a gas it is not calibrated to, it may read “NSR” or “NSC”
followed by a number. If the instrument is calibrated for natural
gas “NSR” (Non Standard Response) likely indicates a heavy non
combustible gas (e.g.: heavier than air, such as carbon dioxide, etc.).
If the response is “NSC” Non Standard Combustible) the gas is likely a
heavy hydrocarbon, such as gasoline, propane, butane, etc.
15.
When being used in dark areas an automatic backlight will illuminate
the display.
16.
To turn instrument off, press/hold the POWER/MUTE BUTTON (A)
until the beeping sound stops and POWER OFF appears on the display.
Release the button and a purge time followed by the shut down will
occur.
