AC/DC CURRENT TRANSDUCER INSTRUCTION MANUAL APPA 32
INTRODUCTION 1.1 Unpacking and checking Upon removing your new Current Transducer from its packing, you should have the following items: 1. Current Transducer with coiled cable output plugs , without battery. 2. Carrying case. 3. Instruction manual. 1-2 Meter Safety Terms as Marked on Equipment. ATTENTION — Refer to Manual. DOUBLE INSULATION — (Protection Class II) DANGER — Risk of electric shock.
Individual protective device must be used if hazardous live parts in the installation where the measurement is to be carried out could be accessible. The barrier is for indicating the limit of safe access of the hand-held part. 1-3 Front Panel Refer to Figure 1 and the following numbered steps to familiarize yourself with the meter's front panel controls and connectors. 1. Red LED — Low battery display. 2. Green LED — Power on display. 3. Coiled Cable Output Leads — Voltage output. 4.

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.
6. If the unit is not to be used for a long period of time , remove the battery. 7. Do not forget to turn power switch off after use. 8. If the meter is used near equipment that generates electro-magnetic , the output may be unstable or indicate incorrect measurement values. THIS INSTRUMENT MUST NOT BE USED ON UNINSULATED CONDUCTORS AT A VOLTAGE GREATER THAN 600V ac/dc. 3-2 AC Current Measurement 1. Select the highest anticipated input (600A or 100A) by the function switch. 2.
3. Press the trigger to open the transformer jaws and clamp one conductor only, make sure that the jaws is firmly closed around the conductor , then read the display from the multimeter directly. 3-3 DC Current Measurement 1. Select the highest anticipated input (600A 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. Adjust the "DCA Zero Adj. knob" until the display shows "0". 4.
Current CAT.II.600V with respect to earth for the jaw. BLACK 10 Barrier for Hand Guard + Do not hold the meter across the Barrier RED Fig.
MAINTENANCE WARNING TO AVOID ELECTRICAL SHOCK REMOVE TEST LEADS BEFORE OPENING THE COVER. 4-1 General Maintenance 1. Repairs or servicing not coverted in this manual should only be performed by qualified personal. 2. Periodically wipe the case with a dry cloth and detergent do not use abrasives or solvents. 4-2 Battery Installation or Replacement The meter is powered by a single 9V battery. Use the following procedure to replace the battery. 1. Disconnect the output plus and turn the power off. 2.
