Greenlee CM-660 General Purpose AC Clamp Skaitiklio naudojimo instrukcija

1. Įvadas

The Greenlee CM-660 is a general-purpose AC True RMS clamp meter designed for accurate electrical measurements. This instrument is capable of measuring AC currents, DC voltages, resistance, and frequency. It incorporates a digital low-pass filter for precise readings on variable frequency drives (VFDs) and features AmpTip™ technology for enhanced accuracy on small wires carrying low currents (60 amps arba mažiau).

Key features include non-contact AC voltage detection, continuity testing, and diode testing. The meter can record average, maximum, and minimum readings, and offers two voltage detection modes: non-contact or single test lead. It is powered by two 1.5V AAA batteries and comes with test leads and a carrying case for convenience. The CM-660 has a 6000-count LCD display and a 1.18-inch jaw opening. It is UL listed, ensuring compliance with safety standards.
