CALIBRATIONS / ADJUSTMENTS
Equipment Required for Calibration:
• Pneumatic Supply capable of delivering up to 150 psig.
• Current Supply capable of delivering up to 60 mA.
• Pressure Gage capable of a digital readout up to 50 psig
with an accuracy of .1%.
• Digital Volt Meter capable of a readout up to 60 mA with
an accuracy of .02%.
FULL RANGE OPERATION
CAUTION: Over-ranging the Zero Screw can damage unit.
Forward Acting Mode Adjustment
1. Connect the input signal to the transducer as shown
in Figure 9.
• Forward Acting Calibration-Zero
2. Apply the minimum input signal and adjust the Zero
screw for minimum output pressure. Turn screw
clockwise to increase pressure and counterclockwise
to decrease pressure.
• Forward Acting Calibration-Span
3.
Apply the maximum input signal and adjust the Span
screw for maximum output pressure. Turn screw
clockwise to increase pressure and counterclockwise
to decrease pressure.
4. Repeat steps 2-3 until the desired output range is
obtained.
Reverse Acting Mode Adjustment
5.
• Reverse Acting Calibration-Zero
6. Apply the minimum input signal and adjust the Zero
• Reverse Acting Calibration-Span
7. Apply the maximum input signal and adjust the
8.
SPLIT RANGE OPERATION
All units have the capability to be split ranged or set for
any output in the range as long as the Output Span is
equal to or greater than the minimum Span.
