Hz Input sensitivity varies automatically with
voltage range selected. 6V range has the
highest & 1000V range has the lowest. Press
SELECT
button momentarily toggles to higher
resolution
VFD-Hz
in main display. The display
shows the selected voltage range for about one
second before displaying Hz readings. Pressing
the
RANGE
button momentarily repeatedly to
display and select any other voltage range. If the
Hz reading becomes unstable, select higher
voltage range to avoid electrical noise. If the
reading shows zero, select lower voltage range
for better sensitivity.

Function defaults at
VFD-ACV
. By default,
voltage is set at 600V & 1000V two auto-ranges to
best cope with most Variable Frequency Drives
(VFD) measurements. High noise-rejection
frequency measurement algorithm and Low-pass
filter circuit are permanently bundled with all
voltage and frequency function-ranges within this
rotary-switch position. Press the
RANGE
button
momentarily to select other ranges only when
needed.
