Function Buttons Press the “MAX” button to display the maximum value. Press and hold the button for more than 2 seconds to exit “MAX” mode. HOLD: The HOLD function holds the currently displayed measured value on the display so that it can be read or logged in peace. Press this button to turn on or off data hold.
Operating Instructions Insert and replace batteries Replace the batteries immediately when the symbol appears in the display. Disconnect the meter from the power source. Remove the test leads from the measuring device, loosen the screws on the back and remove the lower half of the housing, replace the old batteries and screw the cover back on.
Automatic shutdown No operation in 15 minutes, the clamp meter beeps 3 times. Without further operation, the clamp meter beeps again and switches off automatically. Press any key to restore the clamp meter to operating status. The symbol appears on the display. To deactivate the automatic switch-off, hold down the "FUNC."...
Measurement operation AC current measurement The current is measured via the current clamp (1). The sensors in the current clamp detect the magnetic field created by current-carrying conductors. You can take measurements on insulated and not insulated conductors. The test leads should be disconnected from the measuring device when measuring current. Proceed as follows to measure the current: 1) Estimate the current range (2 , 20 or 200 ) and turn the knob to 2 , 20 or 200 .

Attention ► Do not use the current clamp to surround more than one conductor. ► If the supply and return conductors (e.g. L and N) are measured, the currents will cancel each other out and no measurement will be displayed. The cables of household appliances usually contain L and N conductors.
AC/DC voltage measurement Voltage above 600 V cannot be measured! When measuring high voltage, pay special attention to safety to avoid electric shock or injury. 1) Turn the knob to (DC Voltage) or (AC Voltage) 2) Plug the black test lead into the COM socket and the red test lead into the INPUT socket. 3) Then bring the test probes into contact with the points to be measured.
Resistance measurement Ω Do not enter a voltage above 10 V! Make sure that the power supply to the circuit is disconnected and all capacitors are discharged. 1. Turn the rotary function switch to for resistance measurement. It displays "MΩ” on screen. 2.
Continuity test Do not enter a voltage above 10 V! Make sure that the power supply to the circuit is disconnected and all capacitors are discharged. 1. Turn the rotary switch to and press the "FUNC." key several times until appears on the display.
Diode Test Do not enter a voltage above 10 V! Make sure that the power supply to the circuit is disconnected and all capacitors are discharged. 1. Turn the rotary function switch to . Press the "FUNC." key 2 times until appears on the display.
Capacitance measurement 1) Turn the knob to . 2) Insert the red probe in INPUT socket, insert the black probe in COM socket. 3) Contact the probe to the capacitance. 4) Read the measurement result on the screen. Attention When measuring capacitance on the line, disconnect the power supply and discharge all the high-voltage capacitors.
Maintenance Warning • To avoid electrical shock, disconnect test leads from the Meter before removing its back cover. Never use the Meter with the back cover removed. • Repairs or servicing not covered in this manual should be performed only by qualified personnel. Caution •...
