7. Remove jumpers. Jumper TERMINAL 17 to 18 (15 to 16).
8. Reconnect the DC voltage standard as follows, set to +5.0000V dc.
+lead to TERMINAL 8
-lead to TERMINAL 18 (16)
9. Connect the digital voltmeter as follows:
+lead to TP4 (TP5)
-lead to TERMINAL 8
10. Adjust R63 (R60) for a reading of zero at TP4 (TP5).
11. Repeat the procedure for loop 2.
Output Amplifiers, Current Mode
Using the following procedure, configure the output circuits to
current mode and adjust the scaling resistors for correct lower and
upper output limits. At the same time, adjust for a minimum effect
on the output due to changes in load resistance. The adjustments are
interactive and must be repeated until the interaction is minimized.
Complete the procedure for loop 1 before beginning the procedure
for loop 2.
1. Set 1 - Set the programming plug positions for current mode. Refer
to Figure 5.1.
E3 (E1) I, lower position
E6 I, right position
(E2) lower position
E8 (E7) I, right position
E18 lower position for additional compliance.
2. Turn off +5V dc.
3. Place E (E4) in the OUT position.
4. Connect the 1 K and 250 ohm precision resistors in series between
TERMINAL 12 (10) And TERMINAL 11.
