•
The display style of [Hz/
] does not show the bar graph.
•
As a normal condition, non-connected test leads may cause
unstable readings.
Note:
•
Press the SELECT button to alternately change the display
style.
•
By default, voltage is always set at manual-range 500 V to best
cope with most Variable Frequency Drives (VFD) measurements.
Press the RANGE button to select other ranges only when
needed. This function has only manual-ranges.
•
Hz input sensitivity varies automatically with a selected
voltage range. 5.0000 V range has the highest sensitivity and
the 1000.0 V range has the lowest sensitivity. This function
normally set the most appropriate trigger level for most Variable
Frequency Drives. You can also press the RANGE HOLD button
to manually select other trigger levels (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.
