OPERATION This instrument has been designed and tested in accordance with IEC Publication 1010, Safety Requirements for Electronic Measuring Apparatus and has been supplied in a safe condition. This instruction manual contains some information and warnings which have to be followed by the user to ensure safe operation and to retain the instrument in safe condition. 3-1 Precautions and Preparations for measurement 1. Do not apply the voltage to the output plugs. 2.
THIS INSTRUMENT MUST NOT BE USED ON UNINSULATED CONDUCTORS AT A VOLTAGE GREATER THAN 1000V ac/dc. 3-2 AC Current Measurement 1. Select the highest anticipated input (1000A or 100A) by the function switch. 2. Insert the “Output plugs (red and black)” to the input terminals of a Multimeter. Set the Multimeter to “AC 200mV or 2V” range.
3-3 DC Current Measurement 1. Select the highest anticipated input (1000A or 100A) by the function switch. 2. Insert the “Output plugs (red and black) “ to the input terminals of a Multimeter. Set the Multimeter to “DC 200mV or 2V” range. 3. Be sure to zero adjust first. With jaws closed and away from conductor, continue to press DCA AUTO ZERO Button until instrument reads all zeroes or very close to it. 4.
