Tips and Hints

Check the peak currents and their duration. Use the Cursor for readout of momentary
values. Check if fuses, circuit breakers, and conductors in the power distribution system
can withstand the inrush current during this period. Check also if phase voltages stay
stable enough.
High peak currents can cause circuit breakers to trip unexpectedly. Measuring Inrush
Current can help in setting trip levels. Since the Analyzer simultaneously captures Inrush
Current and Voltage Trends you can use this measurement to check voltage stability as
large loads come on line.
Use event capture on Arms ½ to capture high resolution voltage and current rms trends
and to capture waveform signals. This feature is available in Fluke 435-II and 437-II and
can display a 7.5 second trend and a 1 second waveform. To activate this press SETUP,
F4 – MANUAL SETUP, F3 – FUNCTION PREF., F1- WAVE CAPTURE. Then select
