4.0 AUTO POWER OFF FUNCTION
1. If you have not operated the meter for 30 minutes, the meter will turn off automatically and go into Sleep mode. To wake the meter from
Sleep mode, turn the rotary switch or press a button.

400A
To avoid personal injury or damage to the meter, do not attempt to measure voltages higher than 600V AC.
1. Set the Rotary Switch to ACV .
2. Touch the test leads to the circuit under test. With AC voltage, the polarity of the test leads is not a factor.
Note: It is best to touch one of the test leads to ground or neutral first and then touch the 2nd test lead to the hot wire.
3. Read the value of the measurement displayed.
4. Typical AC Voltage measurements include wall outlets, appliance outlets, motors, light fixtures and switches.
5.2 DC VOLTS

400A
To avoid personal injury or damage to the Meter, do not attempt to measure voltages higher than 600 VDC.
1. Set the Rotary Switch to DCV.
2. Touch the test leads to the circuit under test. Touch the black (common) test lead to the
negative DC source (ground) first and red (positive) test lead to the “live” source second.
3. Read the value of the measurement displayed. If the leads are reversed a
“-“ indicator will appear on the display.
4. Typical DC Voltage measurements include car batteries, automotive switches, motors, and household batteries.
5.3 RESISTANCE
When measuring resistance always make sure the power to the circuit is off.
1. Set the Rotary Switch to

400A
400A
. Press SELECT until
Ω
appears on the display.
2. Touch the test leads to the resistor or non-energized component to be measured.
3. Read the value of the measurement displayed. With resistance measurements, the polarity of the test leads is not a factor.
4. Typical resistance measurements include resistors, potentiometers, switches, extension cords and fuses.
Note: For measurements > 1M
Ω
, the meter may take a few seconds to stabilize reading. This is normal for high
resistance measurements. When the input is not connected, i.e. at open circuit, “ OL” will be displayed as an overrange indication.
5.4 CONTINUITY
To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all
the high-voltage capacitors before measuring resistance.
Do not input 60V DC or 30V AC to avoid personal harm. Do not use on energized circuits.
1. Set the Rotary Switch to

. Press SELECT until appears on the display.
2. Connect the test leads across with the object being measured.
3. The buzzer sounds continuously if the resistance of a circuit under test is <~60
Ω
. It indicates the circuit connection is good.
4. The buzzer does not sound if the resistance of a circuit under test is >100
Ω
. It indicates a possible broken circuit.
5. The buzzer may or may not sound if the resistance of a circuit under test is 60
Ω
-100
Ω
.
6. Read the resistance value on the display.
7. Typical continuity measurements include switches, extension cords and fuses.
Note: Open circuit voltage is around 1.5V. When the input is not connected, i.e. at open circuit,
“ OL” will be displayed as an overrange indication.
5.5 DIODE
1. Set the Rotary Switch to symbol.
2. Press the SELECT button until
A

appears on the display.
3. For forward voltage drop readings on any semiconductor component, place the red test lead on the component’s anode and place the
black test lead on the component’s cathode.
4. Read the resistance value on the display.
Note: When measuring resistance, the circuit should be powered off and all capacitors should be completely discharged prior to testing.
A more accurate measurement can be achieved by separating the component from the circuit being tested. When the test leads are not
connected or are reversed, the display will show an over-range symbol “OL”.
