OPERATION AND USE
13.
At any time the operator may save the readings on the display by
pressing the ZERO/SAVE (C) button. This will save all readings for
download at a later time. The memory is factory set to store events. This
can be adjusted from 1-100 at the factory. 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.)
14.
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.
15.
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
(i.e.: 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. If the instrument is calibrated for
propane, “NSR” likely indicates gas lighter than air such as helium . “NSC”
may indicate methane, hydrogen or natural gas.
16.
When being used in dark areas an automatic backlight will illuminate
the display.
17.
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 shut down will occur after the purge time.
