LPT-P- Operation Manual
Step 2
Apply the correct Null gas for the type of sensor installed, for a minimum of 2 minutes.
Step 3
Attach a volt meter to TP1 and TP2. Using the POT RN1 potentiometer (located on the left underside
of the ESH-A board), adjust the voltage to read 0.40 VDC. Verify that the voltage output from digital
multi-meter leads attached to test points TP1 and TP2 on the LPT-P is reading 0.0 VDC. (a Zero and
Span Calibration of the LPT-P will be required if this is not the case).
Step 4
Return the jumpers to their original positions and close the ESH-A.
Step 5
On the LPT-P, in the Sensor Confi guration Menu (passcode 3032), press either ARROW key to scroll
through the menu and select the channel assigned to the ESH-A. Follow the instructions in Section
7.2 Calibrating the Internal Sensor(s)
with the exception of applying the gas to the ESH-A
sensor opening instead of the LPT-P
sensor opening.
