7.4 Calibrating an ESH-A Remote Sensor Connected to an LPT-M
There are two different processes for calibrating an ESH-A Remote Sensor.
One process is for a new or replacement sensor and the other is for a properly
functioning sensor. For either process, first ensure that the sensor has been
continually powered for at least 24 hours.
7.4.1 Zero and Span Calibration of a Responsive ESH-A Remote Sensor (done
at the LPT-M)
If the sensor does not need to be replaced and is responding correctly, the Zero
and Span calibrations will need to be done at LPT-M transmitter that the ESH-A
is connected to.
In the Sensor Configuration Menu (passcode 3032), press either ARROW key
to scroll through the menu and select the channel the ESH-A is assigned to.
Follow the instructions in Section 8.2 Calibrating the Internal Sensor(s)
with
the exception of applying the gas to the ESH-A sensor opening instead of the
LPT-M sensor opening
.
7.4.2 Zero Calibration of a New or Replacement ESH-A Remote Sensor
If a new replacement sensor has been installed, the ESH-A will require a zero
calibration of its sensor. This process will normally be required if the sensor has
been replaced or there is concern that the sensor is not responding correctly.
Make sure the ESH-A Remote Sensor is powered up and has been warmed up
for a 48 hour period prior to calibration.
Step 1
Open the ESH-A Remote Sensor enclosure. Move the jumpers from their resting
position to JP1-1 and JP1-2 (bottom two jumper positions).
