Failure to observe warnings can result in severe injury or death. ■ Avoid working alone so assistance can be rendered. ■ Do not use the clamp meter if the instrument looks damaged ■ Do not use the clamp meter if the tester is not operating properly or if it is wet. ■ Use the clamp meter only as specified in the instruction card or the protection provided by the clamp meter may be impaired. ■ Ensure hands are kept behind the barrier / hand guard when making measurements. ■ Special precautions are necessary when operating in situations where exposed live parts at dangerous voltages may be encountered. Personal protective equipment (not supplied with the instrument) should be used. ■ Use caution with voltages above 30 V AC RMS, or 60 V DC. These voltages pose a shock hazard.3 megger.com CAT IV Measurement category IV: Equipment connected between the origin of the low-voltage mains supply outside the building and the consumer unit. CAT III Measurement category III: Equipment connected between the consumer unit and the electrical outlets. CAT II Measurement category II: Equipment connected between the electrical outlets and the user’s equipment. Symbols as marked on the instrument and instruction card

Equipment protected by double or reinforced insulation Low battery

Conforms to EU directives Application around hazardous exposed live conductors is permitted Do not discard or throw away this product G Caution Take sufficient care not to apply shock, excessive vibration or force to the jaw If the meter is used in the vicinity of equipment that generates large electromagnetic fields, the display may become unstable or the measurements may be subject to large errors.4 megger.com Power Off / On ■ The instrument displays battery capacity when powering up. Replace batteries when 0% is displayed. Auto Power Off Enable / Disable5 megger.com Auto Hold Enable / Disable

In the AUTOHOLD mode, if the measured value remains within ±10 counts over 10 measuring cycles the instrument will beep 3 times; the measured value will be held on the display and “AUTOHOLD” will be displayed. Subsequently if the measured value changes by ±10 counts, the instrument will beep; “AUTOHOLD” will disappear and the instrument will revert to displaying the new readings until the next AUTOHOLD conditions are met. Note: When the AUTOHOLD activates, the displayed reading will be held for 3 seconds if the clamp jaws are removed from the conductor/s. During this time the HOLD key may be pressed to hold the reading indefinitely. Auto Backlight The Auto backlight on the display activates automatically when the instrument is used in very poor light locations6 megger.com AC Current Leakage Current Measurement Recommended applications of instrument with respect to conductors. Note: Measurements made on the earth conductor only will indicate current in the earth conductor but not the entire installation. G CAT III 300 V with respect to earth for the jaw. Barrier for hand guard. G Do not hold the instrument above the barrier.7 megger.com Single / 1 phase 3 wire / 3 phase Single / 1 phase 3 wire / 3 phase8 megger.com 4 wire / 3 phase + neutral

Data Hold Note: Data Hold beep guard The internal sounder will beep continuously with the LCD display flashing in the Data Hold mode when the measured signal is 50 counts larger than the LCD reading. 4 wire / 3 phase + neutral9 megger.com Peak Hold (forcing into the manual range mode) Low Pass Filter (forcing into the manual range mode) ■ The cut-off frequency of the low pass filter is about 100 Hz with an attenuation characteristic of approximately -24 dB / octave.10 megger.com Auto Range / Manual Range11 megger.com Comparator Select a limit level Confirm the limit level Comparing ■ The instrument offers 3 limit values (0.25 mA, 0.5 mA and 3.5 mA) ■ The internal sounder will beep continuously with the LCD display flashing when measured value exceeds the confirmed limit level.12 megger.com Auto Hold13 megger.com Auto Power Off Battery Replacement Maintenance Do not attempt to repair this meter. It contains no user-serviceable parts. Repair or serving should only be performed by qualified personnel. Cleaning Periodically wipe the case with a dry cloth and detergent, do not use abrasives or solvents.
