6.4.2 JUMPER SETTING(S) FOR SENSOR EXCITATION - dc Powered Unit
Your dc-powered meter is capable of supplying either 1.25 to 12Vdc or
24 Vdc sensor excitation. (refer to Figure 6-3).
•
For 1.25 to 12Vdc excitation, install S1A and S4A jumpers, then adjust
the potentiometer (R34) for proper voltage.
•
For 24Vdc excitation, remove S4A jumpers and install S1B.
