Page 3: １．Safety Warnings
1. Safety Warnings ○ This instrument has been designed and tested according to IEC Publication 61010: Safety Requirements for Electronic Measuring Apparatus. This instruction manual contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and retain it in safe condition. - Page 4 Following symbols are used on the instrument and in the instruction manual. Attention should be paid to each symbol to ensure your safety. Refer to the instructions in the manual. This symbol is marked where the user must refer to the ...
- Page 5 ● Do not install substitute parts or make any modification to the instrument. Return the instrument to Kyoritsu or your distributor for repair or re-calibration. ● Do not try to replace the battery if the surface of the instrument is wet.
- Page 6 ○Measurement categories (Over-voltage categories) To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as O to CAT IV, and called measurement categories. Higher-numbered categories correspond to electrical environments with greater momentary energy, so a measuring instrument designed for CAT III environments can endure greater momentary energy than one designed for CAT II.

Page 7: ２．Features
２．Features ● Tear-drop-shaped jaws for ease of use in crowded cable areas and other tight places. ● Accurate true-RMS reading of AC current or voltage with distorted waveform. ●Average function for easy reading of input with large variation. ●Auto-null function for easy zero adjustment. ●Provides frequency reading in AC current or voltage measurement. - Page 8 *Effective Value (RMS) Most alternating currents and voltages are expressed in effective values, which are also referred to as RMS (Root-Mean-Square) values. The effective value is the square root of the average of square of alternating current or voltage values. Many clamp meters using a conventional rectifying circuit have "RMS"...

Page 16: ５．Preparation For Measurement
５．Preparation for Measurement ５－１ Checking Battery Voltage ① Set the function selector switch to any position other than "OFF". ② When the display is clear without "BATT" showing, proceed to measurement. ③ When the display blanks or "BATT" is indicated, replace the battery according to section 8. -
Page 17: ６．Measurement
６．Measurement ６－１ DC Current Measurement DANGER ● Do not make measurement on a circuit above 1000VDC. This may cause shock hazard or damage to the instrument or equipment under test. ● Do not make measurement with the battery compartment cover removed from the instrument. -
Page 18: ６−２ Ac Current Measurement
NOTE ● During current measurement, keep the transformer jaws fully closed. Otherwise, accurate measurement cannot be made. The maximum measurable conductor size is approx. 55mm in diameter. ● When the current flows from the upside (the display side) to the underside of the instrument, the reading is indicated positive. -
