2. CALIBRATION
It is recommended that the DPT ZERO Calibration be performed upon installation. Span Calibration is
not affected by the Zero Calibration. The Span of the unit has been factory calibrated and should only be
adjusted using high accuracy test equipment.
Refer to section 1.1.1.
Zero Calibration Equipment Required:
-
DMM (Digital Multi Meter)
Span Calibration Equipment Required:
-
Low pressure air source (Paragon PS-100 or equivalent)
-
Manometer for measuring low pressure
-
DMM (Digital Multi Meter)
2.1.
DPT ZERO CALIBRATION
The following zero calibration procedure can be performed without the need to perform a span
calibration.
Step 1.
Remove the black rubber plug.
Step 2.
Apply power to the transducer and verify Power Status LED is illuminated.
Step 3.
Using a DMM set to voltage mode, monitor between TP1 (GND) and TP2 (DPT).
Step 4.
With no pressure applied, adjust
DPT ZERO
potentiometer for a reading of
0.0±.001vdc.
Step 5.
Reinstall the black rubber plug.
2.2.
OUTPUT SPAN CALIBRATION
Check the transducer label to determine the voltage output range (0-5vdc or 0-10vdc) and perform the
appropriate output procedure.
Note: It is recommended that a zero calibration be completed before performing a span calibration.
2.2.1. 0-5vdc Output Procedure
Step 1.
Using a DMM set to voltage mode, monitor between (
SIG)
and (
-)
terminal.
Step 2.
Apply full scale pressure (Value shown on the transducer label) to the
High
Pressure port and adjust the
SPAN
potentiometer for an output reading of
5±.01vdc.
Step 3.
Reinstall the black rubber plug.
2.2.2. 0-10vdc
Output
Procedure
Step 1.
Using a DMM set to voltage mode, monitor between (
SIG)
and (
-)
terminal.
Step 2.
Apply full scale pressure (Value shown on the transducer label) to the
High
Pressure port and adjust the
SPAN
potentiometer for an output reading of
10±.01vdc.
Step 3.
Reinstall the black rubber plug.
