100A Digital Micro-Ohmmeter MPK102e
The MPK102e high current micro-ohmmeter is a portable, microprocessor-controlled instrument. It is used to accurately measure very low contact resistances of breakers and switches, busbars, transformers winding and engines, etc, with test currents from 1 mA to 100 A.
- Microprocessor controlled
- Alphanumerical display
- Resolution down to: 0.1
- Resistance reading up to: 200
- Up to 100 A test current
- Kelvin-type (4 - wires) measurement
- Powered by internal battery (up to 10A) or mains supply
- Direct reading (up to 4 digits)
- Overheating protection
- Serial data output (USB)
It employs the 4 terminals-method to avoid measurement errors caused by test leads and their contact resistances. Using its internal rechargeable battery, measurements with up to 10 A test current may be carried out without connecting the equipment to mains supply. It measure with any test current up to 100 A by mains supply. Measurement accuracy is guaranteed by an state-of-the-art signals amplification system, offset-free and of high long-term stability. Test current may be adjusted by the operator and their values are measured using an analog indicator (bargraph). It makes it easy to measure resistances with a significant inductive component, as in the case of big transformers windings. Internal thermal sensors in all sensitive components avoid any damaged caused to the instrument due to overheating.
