Line Frequency functions (Models 237R & 239R only)
Press the Hz push-button momentarily to toggle Hz function. It is only available to Voltage
and Current related ranges.
Input sensitivity varies automatically with the function range selected while activating the Hz
function. 6V function range has the highest and the 1000V range has the lowest. When
activated under DCV, ACV or VFD-ACV voltage function, the trigger voltage range will be
displayed right before starting the Hz readings. Press momentarily the RANGE button can
manually select another trigger voltage range (not available to current ranges). It is
recommended to first measure the signal voltage (or current) level and activate Hz function
in that range to get the most appropriate trigger level. If the Hz reading becomes unstable,
select lower sensitivity to avoid electrical noise. If the reading shows zero, select higher
sensitivity.
