6. How to make measurements

Before making any measurements read safety precautions. Always examine the instrument and
accessories used with the instrument for damage, contamination (excessive dirt, grease, etc) and
defects. Examine the test leads for cracked or frayed insulation and make sure the lead plugs fit
snugly into the instrument terminals. If any abnormal conditions exist, do not attempt to make any
measurements.

6.1. Voltage measurements

1. Turn off power to the device under test and discharge all capacitors.
2. Select mV or V-function with the rotary function-switch.
3. Select the desired AC voltage range or DC voltage range, by pressing MODE-button.
4. Plug the black test lead into the COM input jack on the meter and connect the test lead tip to a
grounded point (the reference point for measurement of voltage).
WARNING! To avoid possible electric shock, instrument damage and/or equipment damage, do
not attempt to take any voltage measurements if the voltage is above 1000 V AC/DC are the
maximum voltages that this instrument is designed to measure. The "COM" terminal potential
should not exceed 1000 V measured to ground.
5. Plug the red test lead into the V//CAP/
where a voltage measurement is required. Voltage is always measured in parallel across a test
point. Turn on power the circuit/device to be measured and make the voltage measurement
reduce the range setting if set too high until a satisfactory reading is obtained.
6. After completing the measurement, turn off power to the circuit/device under test, discharge all
capacitors and disconnect the meter test leads.
