4. Making Measurements

Measuring AC or DC Voltage

Warning:

Do not measure any voltage of over 1000 Vdc or 750 Vac rms to

avoid instrument damage or electric shock.

Do not apply more than 1000 Vdc or 750

Vac rms between the

common terminal and the earth ground to avoid instrument damage

or electric shock.

This multimeter displays DC voltage values as well as their polarity. Negative DC voltages

will display a negative sign on the left of the display.

DC voltage ranges are 60.00 mV, 600.0 mV, 6.000 V, 60.00 V, 600.0 V, 1000 V；

AC voltage ranges are 60.00 mV, 600.0 mV, 6.000 V, 60.00 V, 600.0 V, 750 V.

(1) Rotate the rotary switch to

or . Default is DC measurement mode,

will be displayed. Press

to switch into AC measurement mode, will be

displayed.

(2) Connect the black test lead to the

terminal and the red test lead to the

terminal.

(3) Probe the test points and read the display. Press

to enable and cycle

through the manual ranges.

Measuring Resistance

Caution

: To avoid possible damage to your multimeter or to the equipment under

test, disconnect the circuit power and discharge all high-voltage

capacitors before measuring resistance.

Resistance ranges are 600.0 Ω, 6.000 kΩ, 60.00 kΩ, 600.0 kΩ, 6.000 MΩ, and 60.00 MΩ.
