1. Description

The  

SOURCETRONIC

 

MPK-102e

  high-current   micro-ohmmeter   is   a

portable,   microprocessor-controlled   instrument,   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

.

• Kelvin architecture (four-terminal method).
• Digital reading, alphanumeric display.
• Up to 4½ digits readings. 
• Powered by rechargeable battery or mains supply.
• 0.1 µΩ resolution.
• 200 Ω maximum reading. 
• Overheating protection.

2. Operating principle

This   device   uses   the   Kelvin   Bridge   architecture,   with   four   terminals,
avoiding   testing   leads   resistance   to   cause   error   during   measurement.
Test current may be chosen by the operator and the reading is obtained
by   comparison   through   internal   high-stability   standards.   The   result
appears in the alphanumeric display which is very easy to read.

3. Operating instructions

3.1. Use of test probes

Select the suitable test probes for the measurement you intend to perform
taking into account the current chosen for the test (Cables for up to 10 A
or 100 A). If you use the cables corresponding to 100 A, please verify that
the test probes are tightly fit in their corresponding connectors.
