3.6. 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 11 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 12 6. Press the Start button. The LOW CURRENT message will turn up: 7. 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 13 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. If you need to make any changes in the test leads connections it must be done after pressing the Stop button.

3.7. Display messages When turning the equipment on using the SOURCETRONIC MPK102e 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... -
Page 15: Some Notes About Accuracy
MPK-102e 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 16: Protections
5.2. Temperature protection The time of MPK-102e 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. -
