Page 5: Description
It employs the 4 terminals-method (U/I measuring principle) to avoid errors caused by test leads and their contact resistances. The MRM-200-V2 has a cooling system that allows making a large number of consecutive tests without activation of thermal protection. Under normal ambient conditions (25 ºC) it can perform up to 30 consecutive tests with duration of 1 minute... -
Page 6: Operating Principle
Operating principle This device uses the Kelvin Bridge architecture, with four terminals, avoiding testing leads resistance to cause error during measurement. The operator may choose test current and the reading is obtained by comparison through internal high-stability standards. The result appears in the alphanumeric display that is very easy to read. „... -

Page 18: Protections
Protections The MRM-200-V2 continuous using time is limited by thermal considerations. Some internal sensors measures the temperature of the sensitive parts and trigger the protection that will stop the current generation if any of them exceeds the limit temperature, thus avoiding any damage. The OVERHEATING message will appear in the display. -
