BASIC MEASUREMENT
49
Frequency/Period In-Depth Setting
The input voltage/current range for frequency/period
measurements can be set to Auto range or to manual. By
default, the voltage/current range is set to Auto for both
the period and frequency.
Press the Auto/Enter key. Auto will be
displayed on the upper right corner.
F2 (Gate Time) key
to select gate time
It is the threshold to recalculate
frequency/period. Slower the gate time,
e.g., 1s, more accurate the reading value.
Press the F2 key to enter gate time menu. Click
the F1 – F3 key for the desired gate time. See
the figure below with available options.
F4 (InJack) key to
select voltage or
current
In accordance with the target inputs,
choose the corresponding selection per
condition. E.g., select “3A” when the
input current is below 3A amplitude.
Press the F4 (InJack) key to determine whether
the voltage or current 3A or current 10A
(GDM-9061 only) to be measured. Press the F1 –
F3 key to select desired option. See the figure
shown below with options available.
F5 (Time Out) key
to select timeout
It defines the exact value for timeout,
which means measurement will be
suspended after reaching the set timeout
value when none of input is detected.
