I.
Press and hold the STORE/CLEAR/DIAGNOSTIC button for more than ¾ of a second to activate loop
diagnostic mode. This is available in each of the Model 532's operating modes.
Read Modes:
Read Milliamps
Loop current is displayed.
Power and Measure 2-Wire Transmitter
Loop current, voltage, and resistance is displayed.
Read Volts
Voltage is displayed.
Source Modes:
The EZ-Dialä knob, EZ-Checkä switch, and EZ-Stepä pushbutton
function normally when the loop diagnostic is activated.
Source Milliamps
Loop current, voltage, and resistance is displayed. The resistance is
highlighted if it exceeds the Model 532's output capability (1200 W at
20 mA with HARTâ Compatibility disabled.)
2-Wire Transmitter Simulate
Loop current is displayed. The Model 532 automatically performs a test
every 7 seconds to compute the loop power supply voltage and loop
resistance. The Model 532 requires approximately 2 volts across its
terminals to operate in 2 Wire Simulate mode. The voltage display is
highlighted if there is less than 2 volts present.
Source Volts
Loop current, voltage, and resistance is displayed. The resistance is
highlighted if it exceeds the Model 532's output capability (20 mA into
1200 W with HARTâ Compatibility disabled.)
