DCV, ACV, & Line Frequency functions
Press the Hz push-button for one second or more to activate or to exit Hz.
Note:
*Input sensitivity varies automatically with function range selected before activating the Hz function.
6V function range has the highest and the 1000V range has the lowest. It is recommended to first
measure the signal voltage (or current) level then activate the Hz function in that voltage (or
current) range to automatically set the most appropriate trigger level. You can also press the
RANGE button momentarily to select another trigger level manually. If the Hz reading becomes
unstable, select lower sensitivity to avoid electrical noise. If the reading shows zero, select higher
sensitivity.
*Number of Bar-graph pointer is used to indicate input range (sensitivity) selected. 1/2/3/4 pointers
indicate 6/60/600/1000V, 6/10/-/-A, 60/600/-/-mA or 600/6000/-/-uA is selected in corresponding V,
A, mA or uA function respectively. ( “-” means range not available)
*The Hz of mV function is designed specially for logic level (3V or 5V family) frequency
measurement.
