CAUTION ● Before operating this instrument, familiarize yourself with all instructions outlined in this manual. ● Always check to make sure that the function switch is set to the proper position. ● When making measurements, use CAUTION as dangerous voltages may be present in normally safe areas. ● To avoid electrical shock, use CAUTION when working above 60V DC or 25V AC rms. Such voltages pose a shock hazard. ● Never make measurements with the battery cover OFF. ● Never fail to keep the maximum tolerable input. ● Never operate this instrument if it becomes wet, damp or has any liquid condensation build-up on any part of the instrument. ● Never make measurements for uninsulated conductors or bus bars. 4.

METHOD OF MEASUREMENT ① Set the power switch to “ON” position. ② Set the AC/DC switch to AC or DC depending upon the signal to be measured. Note: In AC current measurement, even if “1” is displayed in the least digit without input, however, it is not abnormal and no influence for the measurement accuracy. ③ Set the range switch to the desired range. ④ Adjust the zero adjustment knob to read zero for DC current measurement. ⑤ Clamp the conductor of the circuit under test with current transducer. Note: Clamp around only one conductor in the circuit to be measured. ⑥ Read the displayed value. ⑦ After measurement, set the power switch to “OFF”. CAUTION: This tester is designed for low voltage applications. To avoid electrical shock or damage, the measurement is limited to the circuit under 600V AC.
