Mastech MS8211D User Manual

4.12 Measuring DC Current
WARNING
Risk of Electrocution.
To avoid damage to the Meter or injury if the
fuse blows, never attempt an in-circuit current
measurement where the open-circuit potential
to earth is greater than 250V
4.11 Continuity Test
WARNING
Risk of Electrocution.
When testing the circuit continuity, be sure
that the power of the circuit has been shut
down and all capacitors have been discharged
fully.
4.11.1 Rotate the probe socket clockwise to spin out the
probe from the meter.
4.11.2 Insert the black test lead or test clip in the COM
jack.
4.11.3 Set the transform switch at the range position.
4.11.4 Put down the “FUNC.” transformed at
continuity test.

4.12.1 Rotate the probe socket anti-clockwise to spin the
probe into the meter.
4.12.2 Insert the black test lead or test clip in the COM
jack.
4.12.3 Set the transform switch at the mA range
position
4.12.4 Press the “FUNC.” button to transform to DC
measurement. Auto range and manual range can
be transformed by pressing the “RANGE” button.
4.12.5 Connect the probe tip of the meter and probe tip
of the test lead (or test clip) in series with the load
in which the current is to be measured.
4.12.6 You can get a reading from LCD display. The
polarity of the tested terminal which the tip of the
meter connection will be indicated.
4.11.5 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.
4.11.6 If continuity exists (i.e., resistance less than
about 50Ω), built-in buzzer will sound.
NOTE:
- If the input open circuit (or the circuit resistance
measured is higher than 200Ω), then the figure‘0L’
will be displayed.
- At the manual range mode, when only the figure ‘OL’ is
displayed, it indicates overrange situation and the
higher range has to be selected.
