Measuring Ac Voltage - Mastech MS8211D Instruction Manual

4.7.5 Connect the probe tip of the meter and probe tip of the
test lead (or test clip) across the power source or be
loaded on the two sides under measurement.
4.7.6 You can get a reading from LCD display. The polarity
of the tested terminal which the tip of the meter
connection will be indicated.
NOTE:
- At the little voltage range, the meter will show unsteady
reading when test leads haven't reach the circuit, it's
normal because the meter is very sensitivity. When meter
touch the circuit, you can get the true reading.
- At the manual range mode, when only the figure 'OL' is
displayed, it indicates overrange situation and the higher
range has to be selected.
- At the manual range mode, when the value scale to be
measured is unknown beforehand, select the range to
the highest position and set down gradually.

4.8 Measuring AC Voltage

4.8.1 Rotate the probe socket clockwise to spin out the
probe from the meter.
4.8.2 Insert the black test lead or test clip in the COM jack.
4.8.3 Set the transform switch at the V
4.8.4 Press the "FUNC". button to transform to AC
measurement. Auto range and manual range can be
transformed by putting the "RANGE"button.
4.8.5 Connect the probe tip of the meter to one side of the
tested circuit and probe tip of the test lead (or test
clip) to the other side.
4.8.6 You can get reading from LCD display.

WARNING
Risk of Electrocution.
You can't input the voltage which is higher than
600V rms AC, it's possible to show higher
voltage, but it may damage the inner circuit or
cause electrical shock.
Pay attention to avoid getting an electric shock
when measuring voltage.
NOTE:
- At the manual range mode, when only the figure 'OL' is
displayed, it indicates overrange situation and the
higher range has to be selected.
- At the little voltage range, the meter will show unsteady
reading when test leads haven't reach the circuit, it's
normal because the meter is very sensitivity. When test
leads touch the circuit, you can get the true reading.
- At the manual range mode, when the value scale to be
measured is unknown beforehand, select the range at
the highest position and set down gradually.
- Transform to the manual range when use the mV
range.
