6 Initial use and operation

Take the device out of the package and remove all packaging material. A battery compartment, which is secured by a screw, is located at the back of the device. Remove the screw, open the battery compartment and insert two 1.5V AAA batteries. Make sure the polarity of the contacts is correct. Then close the battery compartment.

Note: Please use only 1.5V AAA batteries and not rechargeable batteries, since a low voltage of 1.2V may result in device malfunction!

Measurements

Ensure that only the required measuring leads are connected to the device. Remove any measuring leads that are not needed for safety reasons. Measurements in circuits with a possible voltage of more than 50V AC and more than 75V DC should be carried out only by technicians or trained personnel who are familiar with the regulations and the resulting dangers.

Never exceed the maximum permissible input parameters. Do not touch any circuit parts or circuits if they are carrying high voltages (higher than 25V ACrms or 35V DC)! Before measuring, check the measuring leads for any damage. Faulty measuring leads should not be used under any circumstances! Possible danger to life!

Voltage measurement DC (direct current) & AC (alternating current)

1. Connect the red measuring lead to the "VΩmAhFE" terminal and the black measuring lead to the "COM" terminal.
2. Set the range to the desired voltage position. If the voltage to be measured is not known, then set the rotary switch to the highest range (in this case, 600V) and reduce it until a satisfactory reading is shown in the display.
3. Connect the measuring leads to the desired measurement points
