4. Operating Instructions

• No-Contact AC Voltage Detector
The auto power-off and backlight functions are not available in this measurement function.
o Set the rotary switch to the EF- range. The green LED will switch on.
o Place the top of the multimeter as close as possible to the lead or the mains socket. The green LED will turn red and the
multimeter will beep with the presence of an AC electrical voltage.
• Voltage Measurements
To avoid electrical shock and/or damage to the instrument, do not attempt to measure voltages
exceeding 1,000VDC / 750VAC RMS.
To avoid electrical shock and/or damage to the instrument, do not apply more 1,000VDC or 750VAC
RMS between the COM terminal and the earth ground.
o Set the rotary switch to the V (VAC or VDC) range.
o Press the RANGE button to select your range.
o Connect the black and the red test leads to the COM and the V terminals respectively.
o Connect the test leads to the circuit being measured.
o Read the displayed value. The polarity of the red test lead connection will be indicated when making a DC measurement.
• Resistance Measurements
To avoid electrical shock and/or damage to the instrument, disconnect the circuit power and discharge
all high-voltage capacitors before measuring resistance.
o Set the rotary switch to the Ω range.
o Connect the black and red test leads to the COM and Ω terminals respectively.
o Connect the test leads to the circuit being measured and read the displayed value.
o In order to ensure the best accuracy in measurement of low resistance, short the test leads before measurement. Keep the
test probe resistance in mind and subtract this resistance value from the final measured value.
NOTE:
o For measuring resistance above 1MΩ, the multimeter may need a few seconds to stabilize the reading. This is normal for
high resistance measuring.
o When the input is not connected, i.e. at open circuit, "OL" will be displayed for the overrange condition.
• Continuity Measurements
To avoid electrical shock and/or damage to the instrument, disconnect the circuit power and discharge
all high-voltage capacitors before measuring continuity.
