Description |
The Micro-Jr. is a fully automatic microprocessor controlled
10 Amp Micro-ohm meter. This system has the highest measuring
range (0.1 m 
to 400 k
) and the highest accuracy available. It is lightweight, portable
and battery operated.
- The system has an enhanced software program that can
measure and determine a valid reading, which then is placed
in memory. The system will then continue to measure for
the next reading without any operator intervention. This
feature becomes very valuable when trying to make measurements
and not having a free hand to press the test button.
- The Lithium Ion battery allows for continuous operation
for over 5 hours at 10 amps.
- The Micro-Jr. is designed to give highly accurate readings
in the field with laboratory precision.
