4.5 Voltage measurements

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 VDC / 750
VAC. 1000 VDC and 750 VAC are the maximum voltages
that this instrument is designed to measure. The "COM"
terminal potential should not exceed 500V measured to
ground.
1. Insert the black and red test leads into the COM and V-Ω
input terminals respectively.
2. Select the desired AC voltage range (V∼), or DC voltage
range (V
3. Connect the test lead tips in parallel with the circuit to be
measured (e.g. across a load or power supply). Be careful
not to touch any energized conductors. Note the reading.
4. When all measurements are completer, disconnect the test
leads from the circuit under test. Remove test leads from the
multimeter.
For DC voltage readings, the RED lead tip should be
connected to the positive side of the circuit, the BLACK lead
to the negative side.
A minus sign on the left hand side of the LCD will appear if
the leads are connected the other way round.
