Martindale CM82 1000A AC Clamp Meter
Martindale CM82 1000A AC Clamp Meter is designed for the installation, testing and maintenance of domestic and industrial electrical systems. It measures AC current from 0.01A to 1000A across three ranges. Its jaws accept conductors up to 50mm in diameter or bus bars measuring up to 70 x 18mm.
Alongside AC current measurement, the meter measures AC voltage up to 750V and DC voltage up to 1000V. It also supports resistance, capacitance, frequency and continuity checks, giving users several test functions in one compact instrument. Auto-ranging helps the meter select the appropriate measurement range, while the display hold function allows a reading to remain visible for reference.
The Martindale CM82 1000A AC Clamp Meter has a CAT IV 600V safety rating and includes an automatic power-off function. It operates from a 9V PP3 carbon-zinc battery and is supplied with test leads, a carrying case, a battery and a manual. A two-year warranty is also provided.
Key Benefits
- Measures AC current up to 1000A without requiring direct current measurement through test leads.
- Supports domestic and industrial installation, testing and maintenance work.
- Combines AC voltage, DC voltage, resistance, capacitance, frequency and continuity functions.
- Auto-ranging reduces the need to select voltage and resistance ranges manually.
- Display hold keeps a measured value on screen when the display is difficult to view during testing.
- Continuity testing provides an audible buzzer response below 25Ω to assist with circuit checks.
- The 50mm jaw capacity accommodates larger conductors and 70 x 18mm bus bars.
- Automatic power-off helps limit unnecessary battery use after testing.
- CAT IV 600V classification provides a clearly stated safety category for the instrument.
Common Applications
Martindale CM82 1000A AC Clamp Meter is suitable for a range of testing, maintenance and inspection tasks, including:
- Domestic electrical installation testing
- Industrial electrical installation testing
- Routine electrical system maintenance
- AC current measurement on conductors
- AC and DC voltage measurement
- Resistance and continuity checks
- Capacitance and frequency measurement
- Testing conductors and compatible bus bars
Why Choose This Model?
The CM82 provides capacitance measurement, unlike the CM84, while retaining the core AC current, voltage, resistance and frequency functions. It suits buyers who need up to 1000A AC measurement but do not require the CM87 functions shown, such as True RMS, minimum and maximum recording, backlighting, inrush or temperature.
