Operation Examples - AEMC 5050 User Manual

Scroll through the results on the main display with the R-DAR-PI-DD button, or on
the small display with the V/TIME button.
Use R(t) when carrying out a 'time-controlled test' to scroll through the interval
measurement values saved at the sampling rate specified in SET-UP. These
values are available until another measurement is taken or the selector switch is
turned.
When measuring high levels of insulation (> 1GΩ), it is advised that the "G"
guard terminal be used to eliminate the influence of surface leakage currents. The
guard is connected between the two measurement contact points, and the surface
susceptible to surface currents, (e.g. dusty, damp cable or transformer insulation).
In this case, alligator clips are preferable to test-probes held in the hand.
As soon as insulation measurement is stopped, the test circuit is automatically
discharged using the instrument's internal resistance.
