PCE INSTRUMENTS PCE-CM 6 Digital Clamp Meter
INTRODUCTION
This meter is a double impedance high performance true RMS digital clamp meter, which integrates multip-le functions, makes your work easier, more efficient and safer.
It can measure AC/DC voltage, AC/DC current, frequency, duty, resistance, capacitance, temperature, diode, NCV, VFD, inrush current, etc.
High Input Impedance Voltage Measurement:
When measuring in a circuit, it has little effect on circuit performance. This is the desired effect for most voltage measurement applications and is especially important for sensitive electronic or control circuits. Low Input Impedance Voltage Measurement(LoZ V ):
It can safely troubleshoot sensitive electronic or control circuits and circuits that may contain false vol-tages, and can more reliably determine whether there is a voltage on the circuit.

DISPOSAL
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose. In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devi-ces in line with law. For countries outside the EU, batteries and devices should be disposed of in accordan-ce with your local waste regulations. If you have any questions, please contact PCE Instruments.
