3. Set to
PEAK
. The measurement mode is switched
by
SLOW/PEAK/Hz
as follow.
4. Switch between the auto and the manual range as
necessary. (If you are unable to estimate the peak
voltage value, start at the 600 V range.)
5. Attach or remove the rigid insulating sleeve as
required by the measurement category.
6. Carefully contact the test leads to a circuit.
7. Before the measurement, press
0ADJ/RESET
to reset
the residual data.
･
Be sure to use the test leads with the sleeves
attached when performing measurements in the CAT
III measurement category. In a CAT II environment,
if the tips of the test leads do not reach the
measurement object, remove the rigid insulating
sleeve before measuring.
･
The polarity of the input is not displayed during
peak measurements. If the connections of test leads
are moved, the measured values may change, but the
values are within the guaranteed accuracy.
･
You can capture from pulses with a width of about
more than 1ms.
･
To check transitional peak value, press
MAX/MIN
to shift to the Instantaneous value (no annunciator).
･
In peak measurement mode, zero-adjustment is
disabled.
