diode. If the lead connection is reversed, only figure
"1" displayed.
To avoid electrical shock and/or damage to
the instrument, disconnect circuit power and
discharge all high-voltage capacitors before
testing diodes.
4.5 Continuity test
- Set the rotary switch to
range.
- Connect the black and red test leads to the COM and
Ω
terminals respectively.
- Connect the test leads to the resistance in the circuit
being measured.
- When the test lead to the circuit is below 50
Ω
, a
continuous beeping will indicate it.
To avoid electrical shock and/or damage to
the instrument, disconnect circuit power and
discharge all high-voltage capacitors before
testing for Continuity.
4.6 Temperature measurement (Only MS8221B)
- Set the transform switch at the TEMP range position.
- The LCD display will show the current environment
temperature.
- When measuring the temperature with thermocouple,
‘
K
’
type probe for this meter can be used. Insert the
black plug to the COM jack and the red one to the
TEMP jack, touch the end of the temperature sensor
