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. 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).
3. Select the desired AC voltage range or DC voltage range. If
the magnitude of the voltage to be measured is unknown
always start with the highest range.
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 600 V AC/DC are the
maximum voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600 V
measured to ground.
4. Plug the red test lead into the V/-Input jack on the meter
and connect the circuit where a voltage measurement is
required. Voltage is always measured in parallel across a
test point.
5. 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.
