4.0 FUNCTIONS
4.1 HOLD BUTTON
1. Press
HOLD once to enter data hold mode and freeze the displayed value.
2. Press
HOLD again to exit data hold mode and resume normal measurement mode.
4.2 AUTO POWER OFF
1. The
AUTO symbol on the display indicates that the auto power-off feature is enabled.
If you have not operated the meter for 15 minutes, the meter will turn off automatically and go into Sleep mode.
It will beep 1 minute prior to turning off as a warning. To wake the meter from Sleep mode, slide the slide switch or press a button.

400A
400A
To avoid personal injury or damage to the meter, do not attempt to measure voltages higher than 600V AC.
1. Insert the black (negative) test lead into the
COM input terminal.
2. Insert the red (positive) test lead into the
INPUT terminal.
3. Set the Slide Switch to
A
A
400A
400A
4. Press the
SELECT button until AC appears on the display.
5. 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.
6. Read the value of the measurement displayed.
7. Typical AC Voltage measurements include wall outlets, appliance outlets, motors, light fixtures and switches.
5.2 DC VOLTS

To avoid personal injury or damage to the Meter, do not attempt to measure voltages higher than 600 VDC.
1. Insert the black (negative) test lead into the
COM input terminal.
2. Insert the red (positive) test lead into the
INPUT terminal.
3. Set the Slide Switch to
A

400A
400A
4. Press the
SELECT button until DC appears on the display.
5. 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.
6. Read the value of the measurement displayed. If the leads are reversed a
“-“ indicator will appear on the display.
7. Typical DC Voltage measurements include car batteries, automotive switches, motors, and household batteries.
5.3 TEMPERATURE °F °C
1. Set the Slide Switch to
°F°C
2. Temperature can be displayed in both Celsius and Fahrenheit units.
Press the
SELECT button to switch the unit of temperature being displayed.
3. Insert the K-type Temperature Probe into the meter. The negative (-) side of the probe should be connected to the
COM input and the positive (+) side of the probe should be connected to the
INPUT terminal.
4. Touch the sensor (metal tip) of the K-type Temperature Probe to the object being tested.
5. The display will show the temperature measurement being taken.
Note: Never touch the K-type Temperature Probe to an energized circuit.

is shown on the display.
5. 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.
6. 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”.
