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 14: 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. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting. - Page 15 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.
