【1】SAFETY INFORMATION The following are precautions to prevent accidents such as electrical shocks. Be sure to read them before using the CLAMP METER. 1-1 Symbols The following cautionary signs appear on the clamp meter and in this manual. Disobediance to instructions with this sign may lead to troubles of the clamp meter and accidents such as electrical shock.

1-5 Precautions for Safety Measurement WARNING To ensure that the meter is used safely, follow all safety and operating instructions. 11. This meter is a clamp meter exclusive for low voltage. Use it only for circuits of 600V or below. If it is used for measuring the circuit exceeding 600V, it may cause electrical shock or damage to the meter.

【6】MEASUREMENT PROCEDURE 6-1 Startup inspection WARNING 1. Be sure to make startup inspection prior to use. 2. Do not use the meter if the body or test leads are damaged or broken. 3. Make sure the test leads are not cut or the fuse is not blown.* *The meter is OK if the meter pointer moves when the red and black test pins are brought into contact in the resistance range.

6-4 Measuring ACA〜 (max. AC 600A) 1) Applications It is suitable for measurement of alternating current in electric equipment and power supplies. WARNING ・Be sure to disconnect the test lead from the measuring terminals for preventing electric shock. ・If a current to measure can not be estimated, first measure it with the meter in the 150A or 600A range, then change it to a suitable range.
Page 26
General Cautions on Measuring Current ・Close the ends of the iron core (CT) completely. Otherwise, an error may occur. ・AC current measurement does not apply to the frequencies other than sinusoidal 50Hz〜60Hz. ・Clamp only one conductor for measurement. Clamping 2 or more conductors leads to erroneous measurement.

6-5 Measuring Voltage WARNING ・Never apply an input signals exceeding the maximum rating input value. ・Be sure to disconnect the test pins from the circuit when changing the range. ・Always keep your fingers behind the finger guards on the test leads when making measurements.

6-6 Measuring Ω (max. 100kΩ) WARNING Never apply voltage to the "Ω" terminal. 1) Application Resistance of resistors and circuits are measured. 2) Measurement Procedure ①Set the range select knob to the proper Ω range according to the magnitude of the current to be measured. ②Put in the black pin plug to the "COM"...
Page 30
General Caution on Measuring Resistance ・TheΩ range terminals release voltage is about 1.5V. ・The polarity of + and − turns reverse to that of the test leads when measurement is done inΩ range. ・Be sure to use the same rated fuse. In case a fuse other than the same rated one is used, error in indication occurs and/or circuit protection is made unable.
