Frequency Measurement
➭
Set the selector switch to Hz.
The frequency measurement mode is activated. Fre-
quency is displayed at the LCD. Display occurs digitally
only, and is expanded to 9999 digits. Only the auto-
range mode of operation is possible, because the AUTO/
MAN key is required for sensitivity selection.
➭
Apply the measurement magnitude in the same fashion
as for voltage measurement.
➭
Select sensitivity with the AUTO/MAN key. You can
switch between sensitivity levels of 0.1 V, 1 V and 10 mV.
After each activation of the AUTO/MAN key, the corre-
sponding sensitivity level is displayed.
After selection of this function with the selector switch,
the triggering threshold is always set to the highest level
of sensitivity (10 mV).
➭
The lowest measurable frequencies and the maximum
allowable voltages can be found in the chapter “Charac-
teristic Values”.
