Description
The CM-02 Clamp Meter is designed for electricians, automotive technicians, and maintenance staff. Its 3 3/4 digit LCD display with a 40-segment bargraph provides clear readings. The meter supports both auto and manual range selection for versatile measurements.
It measures AC/DC current, voltage, resistance, frequency, capacitance, and temperature. The K-type thermocouple allows accurate temperature readings in Celsius or Fahrenheit. The 23 mm jaw fits easily into tight switch boxes or cable areas. Fast bargraph sampling at 30 times per second captures transient signals reliably. The meter also features one-touch zero for DC current, Max/Min recording, Data Hold, and auto power-off for battery saving.
