MOM2 and CT in loop
For most of the breakers the MOM/DLRO is as accurate as other types of micro-ohmmeters but if there is a current transformer (CT) in series with the breaker contact to be tested then it is advisable to make some basic checks

TORKEL and Grounded Battery
To test a battery system with a higher voltage than the specified max voltage the system can be divided into segments, each with lower voltage and within the specified range. In these cases, it is critical to consider the grounding of the battery system. This application note explain those cases and describe a correct procedure.

Temperature Compensation, TORKEL 900
A battery’s capacity is dependent on the ambient temperature. If the ambient temperature is high the capacity increase, but it will at the same time shorten the battery life. In the opposite direction, when ambient temperature is low, the capacity of the battery is reduced. This must be considered when performing a capacity test.
