6. How to make measurements
Understanding Phantom readings:
In some DC and AC voltage ranges, when the test leads are not
connected to any circuit, the display might show a phantom reading.
This is normal. The meter’s high input sensitivity produces a
wandering effect. When you connect the test leads to a circuit,
accurate reading appears.
6.1. Measuring AC/DC voltage
WARNING!
Do not try to measure a voltage greater than 1000 V DC/AC. You
might damage your meter and expose yourself to a severe shock
hazard.
Follow these steps to measure DC/AC Voltage.
1. Set the rotary selector to the V position. Select the
range as required for the voltage level to be measured. If
you do not know the voltage level, start with the range
switch set to the highest voltage position and reduce the
setting as needed to get a reading.
2. Plug the black test lead into the meter’s COM terminal and
the red test lead into the V/
Ω
/Hz/ -terminal.
3. Connect the test leads to the DC/AC voltage source you
want to measure.
Warning! When you connect the test probes to an AC outlet, do not
turn the rotary selector switch to another range. It could damage the
meter’s internal components or injure you.
