Using Measure Mode
Measuring Electrical Parameters (Upper Display)
To measure the current or voltage output of a transmitter,
or to measure the output of a 700 Series pressure
module, use the upper display and proceed as follows:
1.
Press
to select volts or current. LOOP should
l
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:
1.
Connect the Calibrator to the transmitter current loop
terminals as shown in Figure 8.
2.
Press
while the Calibrator is in current
l
measurement mode. LOOP appears and an internal
24 V loop supply turns on.
When HART resistor mode is selected, the
250 Ω resistor is turned on both mA channels.
