Analog Low (AL CAL) & Analog High (AH CAL) Calibration:
Allows the user to calibrate or “trim” the endpoints of the analog signal output
(i.e. 4mA & 20mA or 0V & 2V/5V)

Calibrating the Analog Signal End-Points:

Step 1: Use a calibrated meter to monitor the analog output signal.

Step 2: Force a low analog output signal (i.e. 4mA or 0V) either by adjusting

the applied pressure or by adjusting the Analog Setpoints (see “Analog

Setpoints”on page 18 for details).

Step 3: Press to enter the main setup menu.

Step 4: Press or to cycle through the options until Output is displayed.

Step 5: Press to access the Output Settings menu.

Step 6: Press or to cycle through the setup options until AL CAL is

displayed.

Step 7: Press to access the Analog Low Calibration value. A 5-digit

number will appear with the fi rst digit fl ashing.

Step 8: Press or to change the value of the fl ashing digit.

NOTE: Changing the digit farthest to the left will produce the coarsest

adjustment, while each successive digit moving to the right will cause

subsequently

fi ner adjustments.

Step 9: Press to accept the value of the fl ashing digit and advance to the

next digit......repeat steps 7 and 8 until the desired Analog Output

value is displayed on the meter.

Step 10: Press to reenter the Output Settings menu.

Step 11: Press or to cycle through the options until AH CAL is

displayed.

Step 12: Repeat Steps 7-9 to adjust the Analog High Calibration value.

Step 13: To exit the output menu, press or until EXIT is displayed and
