The initial state of the meter is the AC/DC voltage automatic identification mode and a symbol of
“SCAN” is displayed; at this time, such buttons as “RANGE”.“MAX/MIN”.“HOLD” have no
controlling functions, and only when “SELECT” button is pressed to select the non-automatic
identification mode of the automatic range can such bottoms as “RANGE”.“MAX/MIN”.“HOLD”
play their function controlling.

Touch the measuring point with the testlead and connect it in parallel to the circuit being tested, and
the polarity of the red testlead wire and the tested voltage value
are spontaneously displayed on the display.
Caution:
a
）
Voltages over DC1000V or AC750V cannot be tested.
b
）
When measuring high voltages, special precautions must be taken
to avoid electrical shock. When measurement is completed,
immediately disconnect the testlead and the measured circuit.
c
）
In case “OL” is displayed under manual range mode, it indicated
the range has been exceeded and it is necessary to select higher
