NOTE
During calibration, datalogging is disabled but calibration events are
recorded in the log.
6. When calibration is complete, the display reads
“AUTOCAL
PASSED”
and then alternates between
“>ACCEPT, ABORT”
and
the gas readings. The gas labels alternate with
‘PASS”
. Press
→
to
accept. The display will show
“CAL ACCEPTED”
, and then
alternate between “REMOVE GAS” and the gas readings.
If you choose to abort, press
↓
to scroll to “
ABORT”
then
→
to accept
the abort option.
The display will read
“CAL ABORTED”
and then alternate between
“REMOVE GAS”
and the gas readings.
NOTE
A
“WEAK”
or
“FAIL”
flag may appear in place of the
“PASS”
flag
in the case of a weak or failed sensor. See the instructions in the
Calibration Alarms section, later in this chapter for corrective action.
7. Remove the tubing from the probe. After fresh air has been detected,
the display will alternate between
“ALARMS SILENCED”
, and the
readings, and then return to the normal operating mode, after an
“ALARMS ACTIVE”
message is displayed.
8. Unscrew the regulator from the cylinder, leave the components of the
calibration kit assembled for convenience and place in the storage
case.
Calibration of Toxic Gases other than H
2
S & CO or for 0-100% Vol
TC Sensor
These calibration gases are only available in single-gas cylinders. Therefore a
multi-step calibration process has been programmed into the Auto Calibration
routine. First, the standard sensors are calibrated using a multi-gas mixture.
Then the first sensor is calibrated using a single-gas cylinder, and repeated if
your unit has a second sensor.
1. Begin the calibration process by performing an Auto Calibration. The
non-standard sensor(s) will be ignored during the multi-gas
calibration.
