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. Make sure that the battery is properly connected. 2.
7. If the meter is used near equipment that generates electromagnetic noise, the display may be unstable or indicate large errors. 8. Maximum rated voltage to earth for voltage measurements terminals is 600V CAT. Ⅲ. 9. When using the instrument as a Voltmeter or ohmmeter never clamp the jaws around or onto a conductor. THIS INSTRUMENT MUST NOT BE USED ON UNINSULATED CONDUCTORS AT A VOLTAGE GREATER THAN 600V ac/dc. 3-2 AC Current Measurement 1. Set the function switch at desired current position. 2.
3-3 AC Voltage Measurement 1. Set the function switch at " V ~ " position. 2. Connect the black test lead to the "COM" terminal and the red test lead to the " V-Ω" terminal. You can now place the test probes on the conductors to make the measurement. 3-4 Resistance Measurement 1. Set the function switch at " Ω " position. 2. Connect the black test lead to the "COM" terminal and red test lead to the " V– Ω " terminal. 3. Verify that the power to the circuit under test is off.
MAINTENANCE WARNING : TO AVOID ELECTRICAL SHOCK REMOVE TEST LEAD BEFORE OPENING THE COVER. 4-1 General Maintenance 1. Repairs or servicing not converted 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 Replacement WARNING : Before opening the battery cover, remove the test leads (or jaw) from the circuit and shut off the unit. 1. Disconnect the unit from the circuit.
