Each channel that was calibrated displays a PASS or FAIL indication alternating
with RUN data. Samples are shown below. These messages will disappear after
one minute. The calibration data is updated only if the calibration passed. The
event is logged in the event queue only if the calibration passed or failed.

5.1.3.2 Zero Calibration Procedure
•
Activate the CALIBRATION mode by selecting the
SETUP-RUN CALIBRATION
menu parameter at the receiver.
•
The LED on the sensor/transmitter assembly to be calibrated will begin flashing
(this LED is continuously lit during normal operation).
•
Expose the sensor to
ZERO
gas (refer to section 5.1.2) and immediately begin the
CALIBRATION process by placing the “magnetic wand” over the area indicated on
the sensor’s data label for about 5 seconds. Figure 5.1 shows a sample sensor data
label and the correct magnetic wand orientation for proper CALIBRATION activation.
NOTE
During the ZERO calibration, there is no time limit
between the time RUN CALIBRATION is selected and the
time the sensor’s magnet is activated. Level alarms are
permitted until the sensor’s magnet is activated and
will abort the calibration if they occur.
•
If the magnet has activated the sensor calibration properly, the LED stops flashing
and remains continuously lit indicating that the calibration process has begun. The
receiver’s LCD display reads “IN ZERO” during ZERO calibration.
•
Once the unit has completed the ZERO CALIBRATION cycle (this may take as
long as five minutes), the LED will signal whether the sensor has passed or failed
CALIBRATION:
PASSED
- LED indicates 2 quick flashes every 2 seconds and unit is ready to
proceed
to
the
SPAN CALIBRATION.
FAILED
- LED will flash once every 2 seconds. The sensor did not meet the “pass
calibration”
criteria.
If the calibration(s) performed passed, the unit will remain in the “IN CAL” mode for
15 minutes, awaiting the activation of the SPAN CALIBRATION (refer to section
5.1.3.3).
If
SPAN CALIBRATION is not started within that time, the receiver will
resume normal operation in the run mode.
NOTE
When the ZERO CALIBRATION is completed, the
unit will automatically prepare to run the SPAN
calibration. When the ZERO calibration ends, the operator has
15 minutes to activate the sensor’s magnet to begin the
SPAN CALIBRATION. If the magnet is not activated during this
period, the unit will revert to run mode and a "stop calibration”
entry will be made in the event queue.
NOTE
If ZERO CALIBRATION has failed, the display will indicate the
result for 5 minutes and a SPAN CALIBRATION cannot
be performed. If a SPAN CALIBRATION is attempted during
that time, the activation of the sensor’s magnetic switch will be
ignored. The unit will automatically return to the RUN mode using
the data from the previous successful CALIBRATION.
