Using Measure Mode Measuring Electrical Parameters (Upper Display) To measure the current or voltage output of a transmitter, use the upper display and proceed as follows: 1. Press A to select current. LOOP should not be on. 2. Connect the leads as shown in Figure 7. Current Measurement with Loop Power The loop power function activates a 24 V supply in series with the current measuring circuit, allowing you to test a transmitter when it is disconnected from plant wiring. To measure current with loop power, proceed as follows: 1. Connect the calibrator to the transmitter current loop terminals as shown in Figure 8. 2. Press K while the calibrator is in current measurement mode. LOOP appears and an internal 24 V loop supply turns on.
