Zero Suppression Calibration (for 0 to 10 VDC Output)
To perform a 0 to 10 VDC calibration, follow the instructions for the ±5 VDC calibration, then displace the LVDT core or the
RVDT shaft to the minus full scale position (-5VDC output between pins 9 and 10). Using the table below, select a
+4 Volt offset
:
S2-C
S2-D
Offset
OFF
OFF
None
ON
OFF
-4VDC
OFF
ON
+4VDC
After zero switches are set, the output at the minus full scale position should have changed to
–
1VDC approximately.
Using the ZERO potentiometer, adjust the DC output until it changes to zero VDC, from the original -1VDC. Return to the original
zero (mid) position; you should now read +5 Volts DC instead of zero. Continue in the same direction up to the original positive
full scale position; the reading should be +10 VDC. The output was shifted by +5VDC; your calibration is now complete for a 0
to 10VDC output range.
Other custom DC output ranges can be achieved by using different ZERO potentiometer adjustments and/or offset switch
settings.
