Calibration
Series 1 Analog Card
Note: The Series 1 Analog Card will be designated as Rev 0 in the Control
Information Diagnostic screen.
Board Marking PC-012-1098 Rev. B
Part # PCBS-0010-B
After the voltage divider card and control cabling have been connected, the
system is ready to be calibrated for use.
Analog Offset: To adjust the Analog Offset, place a jumper on the Analog In
signals on the Analog input card or at the 9C connection for the Analog Input
Card located at the back of the control. The analog input voltage would then be
viewed at the I/O Diagnostics screen to read any incoming voltage for the THC. If
any voltage is displayed at the diagnostic screen, an Offset Voltage equal to the
incoming voltage being read can be entered at the Password protected Analog
I/O screen to correct for any imbalance and “zero” the incoming voltage
Example: If an incoming Analog Input Voltage is reading .1 volts, simply enter .1
at the Analog Offset and correct the imbalance.
