3. Attach three more 250 ohm resistors across Channels 2, 3, and 4
(Figure 6.7).
4. Place the LAST STATE configuration jumpers in the MAX
position (if they are not there already).
5. Connect a voltmeter across the top two screws on the field wiring
arm (top screw is positive, and second screw is negative).
6. Turn processor, I/O chassis, and industrial terminal ON.
7. Place processor in the TEST or PROG mode.
8. Output full scale (+50mA) with write block transfer data.
9. Adjust R66 (Figure 6.6) until the reading is +12.5V (50mA)
+5mV.
10.Repeat steps 8 and 9 for channels 2, 3 and 4. Adjust as necessary
until the desired tolerance is obtained. Associated resistor
potentiometers are shown in Table 6.D.
