J. Modes of Operation
Read Milliamp
Connect the Model 532 in series with
the process loop to monitor current.
Observe correct polarity. Current
limiting above 24.000 mA is indicated
by a flashing “CURRENT LIMITED”
display.
Power and Measure 2 Wire Transmitter
The Model 532 provides power to the process
loop while displaying output current. Use this
mode to test a transmitter’s ability to control
loop current. Current limiting above 24.000
mA is indicated by a flashing “CURRENT
LIMITED” display.
Read Volts
The Model 532 measures +/- 30 VDC with 4X
overrange ability. The display flashes
“OVERRANGE” when the 30 volt limit is
exceeded. 0.001 volt resolution below 24.00
volts provides the ability to calibrate 1-5 volt
instrumentation.
