Making Basic Measurements
Preparation and Caution Before Measurement
Observe the rules
CAUTION
• When connecting the test leads to the DUT (Device Under Test) connect the common
test leads before connecting the live test leads; when removing the test leads, remove
the live test leads before removing the common test leads.
Measuring AC Voltage and DC Voltage
This meter have true rms readings, which are accurate for distorted sine waves
and other waveforms (with no dc offset) such as square waves, triangle waves, and
staircase waves.
The ranges of measuring voltage are 40mV, 400mV, 4V, 40V, 400V and 1000V. To
select the mV range, turn the rotary switch to mV position.
For best accuracy when measuring the DCmV, touch the probe tips together and read
the DC offset. If necessary, you can use the relative (Δ) mode to automatically subtract
this value.
ACV
mV
In AC mode, the frequency may be show dashes if the signal is smaller than the min.
sensitivity and trigger level. Please see "Sensitivity and Trigger level" table in the
Warnings and
Cautions.
