Protections; Start With I = O; Temperature Protection - TENTECH MPK 102e Manual De Uso

5. Protections

5.1. Start with I = O

Very quick variations of the current may cause damages to sensible
items. In order to avoid them, the equipment has a protection that
imposes to start the test with zero current. You can only start the
measurement if the current adjust control is at the start of its course. If
this were not the case, the Start would be inhibited and the message
would say START WITH I=O. If the operator sharply increases the test
current by quickly rotating the Test current control clockwise, the
equipment will impose a slow current growth, in order the current to softly
come to the selected value.

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. The Thermal protection led will light on and the
OVERHEATING message will appear in the display. Under these
conditions, measurements will be inhibited in the 100 A range.
Measurements in other scales may be carried out normally, though the
LED indicator keeps on being displayed up to the temperature decreases
sufficiently.
