RANGE
Pushing the RANGE push button selects a fixed manual range: 60 A first
and 600 A on the second push. The digital display and the bar graph indi-
cate the selected range. RANGE is displayed at the top of the display indi-
cating a manual range selection. Selection is also confirmed with audible
tone.
To sequence back to Auto Ranging, push and hold the RANGE push but-
ton for approximately 3 seconds. The displayed RANGE indicator will dis-
appear, confirmed with an audible tone.
The bar graph ranges are 60 A and 600 A and are also manually selected.
The analog bar graph will continue to display current values while other
measurement functions are displayed (i.e., %THD, %DF, %CF).
In manual range, the ranges (60 A) and (600 A) are extended respec-
tively to 100 A and 1000 A for a better resolution of 1000 counts.
