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.
