3.2.1 AC Current measurement

Make certain that all test leads are disconnected from the meter terminals.
- Set function switch to the A ~ range.
- Clamp the current transducer (jaw) around one of the conductors under test. Make sure
that the clamp jaw be perfectly closed.
- Read the display value.

3.2.2 DC Voltage measurement

Maximum input voltage of DCV range is 1000VDC. Do not attempt to take any
voltage measurement that exceeds 1000VDC to avoid electrical shock and/or
damage to the instrument.
- Set function switch to the V
- Connect the black and red test leads to the COM and V terminals respectively.
- Connect the test leads to the circuit being measured and read the displayed value.

3.2.3 AC Voltage measurement

Maximum input voltage of ACV range is 750Vrms. Do not attempt to take any
voltage measurement that exceeds 750Vrms to avoid electrical shock hazard and/
or damage to the instrument.
- Set the function switch to the V ~ range.
- Connect the black and red test leads to the COM and V terminals respectively.
- Connect the test leads to the circuit being measured and read the displayed value.

3.2.4 Resistance measurement

Before taking any in-circuit resistance measurement, remove power from the
circuit being tested and discharge all capacitors.
- Set the function switch to 
- Connect the black and red test leads to the COM and V terminals respectively.
- Connect the test leads to the circuit being measured and read the displayed value.
Some tips for measuring resistance:
- The measured value of a resistor in a circuit is often different from the resistor's rated
value. This is because the Meter's test current flows through all possible paths between
the probe tips.
- In order to ensure the best accuracy in measurement of low resistance, short the
test leads before measurement and memory the test probe resistance in mind. This
necessary to subtract for the resistance of the test leads.
- The resistance function can produce enough voltage to forward-bias silicon diode or
transistor junctions, causing them to conduct. To avoid this, do not use the 20M range
for in-circuit resistance measurements.
