Digital multimeter
To measure DC/AC voltage:
1. Turn the rotary switch to the DC or AC voltage position; press RANGE for
manual range if needed.
2. Connect the red test lead to the V input jack and the black test lead to the
COM jack.
3. Connect the test leads in parallel to the circuit undertest.
4. Read the measured voltage on the display. When measuring DC
voltage,the display will show the polarity of the red lead.
Note
: In small voltage ranges, the display may show a reading before leads
are connected. This is normal because of the high sensitivity of the meter.
Once the leads are connected to a circuit the true voltage will be displayed.
Resistance
Warning
Turn off all power and discharge all capacitors before making resistance
mesurements.
R
esistance ranges are: 400.0Ω, 4.000kΩ, 40.00kΩ, 400.0kΩ, 4.000MΩ,
40.00MΩ.
To measure resistance:
1. Turn the rotary switch to the
position. The default mode is
resistance.
2.
Connect the red test lead to the Ω input jack and the black test lead to the
COM jack.
3. Connect the leads to the resistance or circuit under test.
4. Read the measured resistance on the display.
Tips for measuring resistance:
• Measured resistance and a components rated resistance often differ
slightly. This is normal due to the test current flowing through all possible
paths between the leads.
• When measuring low resistances, short the test leads and record the
measurement. Then connect the leads to the resistance to be measured
and subtract the shorted resistance from the measured resistance.
•
When the measured resistance is greater than 1MΩ, wait a few seconds for
readings to stabilize. This is normal for high resistance measurements.
• When the circuit is open or leads not connected, the
display will show OL.
