head in the same position. This will slow down the tick and allow
the operator to find a higher concentration using the same pro-
cedure.

If the tick goes away you have moved away  from the leak or
there is no more gas present. The leakage rate may be less
than the rate that the pump is drawing the sample. For best
results always use the leak detector prior to using any liquid
leak detection fluids as these sensors will detect their presence.

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 6 events. This can be adjusted from 1-15 at the
factory. The most recent save is first during download. An op-
tional 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 proce-
dures 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 read-
ings may change. Audible and visual alarms will activate when
the preset limits are reached.

15. If the instrument encounters a gas it is not calibrated to, it
may read “NSR” followed by a number. If the instrument is

calibrated for natural gas “NSR” (Non Standard Reading) likely
indicates a heavy gas (i.e.: heavier than air, such as gasoline,
propane, carbon dioxide, etc.). If the instrument is calibrated for
propane, “NSR” likely indicates gas lighter than air such as hy-
drogen, helium, methane 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 BUT-
TON (A) until the beeping sound stops, about 5-6 seconds. Re-
lease the button and power down will occur.

CALIBRATION CHECK

To verify the accuracy of any Sensit®Gold CGI, it must be
exposed to a known concentration of test gas that will test any
sensor combination included in your particular model.

Any sensor that does not meet the specifications listed in this
manual may require calibration or repair.  A calibration check
does not update the calibration due date. Full calibration is re-
quired to update these times.

A calibration past due message will illuminate during warm-up if
calibration has not been performed per your company specified
interval. Any time it is suspected that the Sensit®Gold CGI is
not working properly, check calibration.
