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
