Voltage to be
Measured
Positive Lead
Negative Lead
Acceptable Range
-12 VDC (REF)
Pin #2
Pin #1
-12.0 VDC ±10%
2. Connect DMM leads to +12 V and ground at the pressure transducer
(Baratron). 12 V (REF) is within specifications. The Block 2
voltages can also be measured at the connector.

Analog to Digital Set Point Test
1. Remove the A/D board, and install a 40 pin IC test clip on IC-8.
Install an extender board in the A/D board slot and plug the A/D
board into the extender. Apply power to the enclosure by enabling
the safety interlock, and allow 15 minutes for the system to stabilize.
(System stabilization is not necessary for Block 2 It is vital for
systems using the old style A/D PCBs.)

Note: On newer boards the test points and adjustment pot are
located at the edge of the board.
2. Measure the voltage between IC-8 pin 39, and IC-8 pin 36. Verify the
voltage measured is 2.048 VDC ±0.005 VDC.
