Page 4: Description
1. Description The SOURCETRONIC MPK-204e 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 200 A. • Kelvin architecture (four-terminal method). -

Page 7: Measurement
3.4. Measurement Warning • Before to use this instrument the User guide and Safety warnings must be read and understood. • Safety procedures and rules for working near high voltage energized systems must be observed during the use of this equipment. The generated voltages and currents may be dangerous. - Page 8 2. Switch the equipment On using the On/Off switch. 3. Using the Range selector, choose the range and the current to use 4. Be sure that the Test current control is at the start position (counter-clockwise completely rotated). Otherwise, Start button will be inhibited and the display will show the message: 5.
- Page 9 6. Press the Start button. The LOW CURRENT message will turn up: Turning the Test current control clockwise, increase current until obtaining the desired value or until the current bargraph reads 100 divisions. The bargraph will show the test current value as the percentage of the nominal value selected by using the Range selector.
- Page 10 12. Press the red button Stop in order to finish the measurement. 13. Finally, when finishing measurements, turn the equipment off using the On/Off switch. Precaution: Do not connect or disconnect the test leads during the measurement.

Page 11: Display Messages
3.5. Display messages When turning the equipment on using the On/Off switch, this introduction message appears for a while. This message appears each time the equipment needs to adjust any parameter in order to optimize the readings. Warns the operator that to be able to start a test, the Test current control must be at the zero position (fully counter- clockwise). -
Page 12: Some Notes About Accuracy
MPK-204e has an auto-compensation system that automatically eliminates the error produced by internal offset. Thus, it is not necessary to carry out measurements by reversing the polarity in order to compute the average value. -
Page 13: Protections
5.2. Temperature protection The time of MPK-204e continuous use is limited by thermal considerations. Some internal sensors measure the temperature of the sensitive parts and trigger the protection that will cut the current circulation, if any of them exceeds the limit temperature, thus avoiding any damage. -
Page 14: Battery Condition
6.1. Battery and charger Battery description The SOURCETRONIC MPK-204e micro-ohmmeter uses a rechargeable 12 V battery. Charging procedure: • Check that the On/Off key is OFF. -
Page 15: Rs232 Output
At the end of battery useful life, the battery must be recycled or disposed of properly, in order to protect the environment. The rechargeable battery does not show the “memory effect” and there are no restrictions to start charging it as many times as is needed. However the battery could be damaged if remains in deep discharge for a while. -

8. Replacement fuse To check the instrument fuse, remove it with a screwdriver. If the fuse is ruptured replace it by another with the following specifications: Fuse Schurter, model SPT 5 x 20 (Time-lag) 8A/250V. High breaking capacity. 9. Cleaning Cleaning of this instrument should be carried out using a soft cleaning liquid, after verifying that it doesn’t affect the plastic parts used in the case and in the Control Panel of this equipment. -
