Page 10: ５．Preparation For Measurement
５．Preparation for Measurement ５−１ Checking Battery Voltage ①Set the function selector switch to any position other than "OFF". ②When the display is clear without "BATT" showing, proceed to measurement. ③When the display blanks or "BATT" is indicated, replace the batteries according to section 8: battery replacement. NOTE ●... -
Page 11: ６．Measurement
６．Measurement ６−１ Current Measurement WARNING ●Do not make measurement on a circuit above 750V AC. This may cause shock hazard or damage to the instrument or equipment under test. ● Transformer jaw tips are designed not to short the circuit under test. - Page 12 ③Take the reading on the display. NOTE ● During current measurement, keep the transformer jaws fully closed. Otherwise, accurate measurement cannot be made. The maximum measurable conductor size is 54.5mm in diameter. ● When measuring a larger current, the transformer jaws may buzz. This is not a fault and does not affect the accuracy at all.

Page 13: ６−２ Voltage Measurement
６−２ Voltage Measurement WARNING ●Do not make measurement on a circuit above 750V AC or 1000V DC. This may cause shock hazard or damage to the instrument or equipment under test. ●Do not make measurement with the battery compartment cover removed. ●Keep your fingers and hands behind the barrier during measurement. -
Page 14: ６−３ Resistance Measurement
６−３ Resistance Measurement WARNING ●Before attempting to make measurement, make sure that the circuit under test is not live. The instrument is protected against a voltage up to 600V. ●Do not make measurement with the battery compartment cover removed. ●Keep your fingers and hands behind the barrier during measurement. ６−３−１ Resistance Measurement (Normal Mode) ①Set the function selector switch to the "Ω/ "... -
Page 15: Continuity Check
６−３−２ Continuity Check ①Set the function selector switch to the "Ω/ " position. ②Slide the terminal cover to the left. Plug the red test lead into the V/Ω terminal and the black test lead into the COM terminal. ③Press the mode button to set the instrument to the continuity check mode. -
Page 16: ７．Notes On Functions ７−１ Data Hold
７．Notes on Functions ７−１ Data Hold This is a function used to freeze the measured value on the display. ①Press the data hold button. The reading becomes frozen and the "H" symbol is shown on the display, indicating the instrument in the data hold mode. -
