10. Repeat Steps 5-8 until all the readings are correct with no further adjustments
necessary.
11. Turn power OFF. Set DIP Switch #7 ON (deg. C). Move DVM (+) plus lead to
Signal conditioner connector terminal 11 (terminal 4 for CH-2). Turn power back
ON.
12. Set mV Source as follows, and adjust "Deg. C Lo Pot" for the corresponding
DVM reading. Actual should read the value shown.

16. If calibrating one channel at a time, power-down the Series 1500 and mV Source.
Move the C/J Compensator from the CH-1 connector terminals to the CH-2
terminals, and move the shorting wiring to the CH-1 terminals. Then perform
Steps 6-14 for CH-2.
