6.

Adjust R66 (R65) until the tieback input reading just becomes OFFF
hex.

7.

Repeat for loop 2.

8.

Place E11 (E12) in its initial position, IN or OUT, and remove the
jumper from the wiring arm.

Output Amplifier, Voltage Adjustments

Using the following procedure, configured the amplifier circuits to
voltage mode and adjust the outputs to 1.000V dc and 5.000V dc for
programmed values of 0 and full scale, respectively.

1.

Set the programming plug position for voltage mode.

E3 (E1) V, upper position
E5 (E4) IN position
E6 V, left position
(E2) upper position
E8 (E7) V, left position
E18 upper position, standard compliance

2.

Connect the digital voltmeter as follows:

+lead to TERMINAL 12 (10)
-lead to TERMINAL 8

3.

Adjust R11 (R5) for an output voltage reading of 1.000V dc.

4.

Change E5 (E4) to the OUT position. Turn off +5V dc.

5.

Adjust R12 (R7) for an output voltage of 5.000V dc.

6.

Repeat for loop 2.

7.

Set the programming plugs on the analog board to their initial
positions as recorded in section titled Installation.
