MEASUREMENT OPERATION
• Make sure the Sleep Mode is not on if you found there is no display on the LCD after turning
on the Meter.
• Make sure the Low Battery Display
is not on, otherwise false readings may be
provided.
• Pay attention to the
symbol which is located besides the input terminals of the Meter
before carrying out measurement.
A. DC VOLTAGE MEASUREMENT
(see figure 3)
Warning!
To avoid harms to your or damages to the Meter from electric shock, please do not attempt to
measure voltages higher than 1000V or 750V rms although readings may be obtained.
The DC Voltage ranges are: 200mV, 2V, 20V, 200V and 1000V. To measure DC voltage,
connect the Meter as follows:
1. Insert the red test lead into the
ºC input terminal and the black test lead into the
COM
input terminal.
2. Set the rotary switch to an appropriate measurement position in
range.
3. Connect the test leads across with the object being measured.
The measured value shows on the display.
(figure 3)
Note
• If the value of voltage to be measured is unknown, use the maximum measurement position
(1000V) and reduce the range step by step until a satisfactory reading is obtained.
• The LCD displays “
1
” indicating the existing selected range is overloaded, it is required to
select a higher range in order to obtain a correct reading.
• In each range, the Meter has an input impedance of approx. 10MW. This loading effect can
cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal
to 10kW, the error is negligible (0.1% or less).
• When DC voltage measurement has been completed, disconnect the connection between
the testing leads and the circuit under test.
