Make adjustments with the EZ-Set Dial or test limits with the Dual Action EZ-Span Switch. Powerful ramping functions are only a button away on the Model 532. Save potentially hours of troubleshooting time on problem loops with the 532’s unique Loop Diagnostic Mode. In Loop Diagnostic Mode, the loop current, voltage, impedance, AC voltage, and mode of operation are all displayed simultaneously; without the need of multiple DMM connections.
