DC Current Measurement

Note: Make sure that all the test leads are disconnected from the meter's terminals for current measurement.

1. Set the rotary switch at 400A DC.
2. Push the zero button to adjust the reading to zero.
3. Press the trigger to open the jaw and fully enclose the conductor to be measured. No air gap is allowed between the two half jaws.

AC Current Measurement

Note: Make sure that all the test leads are disconnected from the meter's terminals for current measurement.

1. Set the rotary switch at 400A AC
2. Press the trigger to open the jaw and fully enclose the conductor to be measured. No air gap is allowed between the two half jaws.
3. Read the measured value from the LCD display

DC voltage measurement

Note: Maximum input for DC V is 600, and for AC V is 600. Do not attempt to take any voltage measurement that exceeds the limits. Exceeding the limits could cause electrical shock and damage to the clamp meter.

1. Set the rotary switch at V DC.
2. Insert the test leads into the input jack.
3. Connect the test prods of the test leads in PARALLEL to the circuit to be measured.
4. Read the measured value from the LCD display.

AC voltage measurement

Note: Maximum input for DC V is 600, and for AC V is 600. Do not attempt to take any voltage measurement that exceeds the limits. Exceeding the limits could cause electrical shock and damage to the clamp meter.

1. Set the rotary switch at V AC
2. Insert the test leads into the input jack.
3. Connect the test prods of the test leads in PARALLEL to the circuit to be measured.
4. Read the measured value from the LCD display.

AC and DC Power and Watt Measurement

1. Connect the test leads to the voltage source in parallel with the load.
2. Clamp on one of the wire to the load.
3. Select the range to Voltage AC or DC, and check the voltage reading.
4. Select the range to Current AC or DC, and check the current reading.
5. Select appropriate Watt range 40KW (0 - 250V, 0 - 400A) or 240KW (0 - 600V, 0 - 400A).
6. Read the value shown on LCD in KW (AC+DC).

Frequency (Hz) Measurement

1. Set the rotary switch at Hz.
2. Insert the test leads into the input jack.
3. Connect the test prods of the test leads in PARALLEL to the signal or circuit to be measured.
4. Read the measured value from the LCD display.

Frequently Asked Questions

How can I check MAX and MIN values when using AKTAKOM ATK-2040 clamp meter?

How to recover from Auto-Power-off when using AKTAKOM ATK-2040 clamp meter?

How can I check MAX and MIN values when using AKTAKOM ATK-2040 clamp meter?

Press the MAX/MIN button to enable the maximum and minimum values to be recorded and updated during measurement. Push the button once, the maximum value shall be displayed and updated. The LCD display toggles between the MAX and MIN values. To exit MAX/MIN function, press and hold the MAX/MIN button for more than 2 seconds. If MAX/MIN button is pressed, the ZERO function will be disabled and the ZERO symbol will disappear from LCD. Up

How to recover from Auto-Power-off when using AKTAKOM ATK-2040 clamp meter?
The meter will turn itself off 15 minutes after power-on (A symbol of APO is displayed in LCD). To turn it on again, user can either press any button or turn the rotary switch. Also pressing any button or turning the rotary switch will reset the 15 minute timer. To disable the Auto-Power-Off function, hold the HOLD button while turning on power. Up
