Measurement Ranges
Full Scale Resolution Volts (full scale) Max Test Current*
999.9 µΩ 0.1 µΩ 0.6 V 600 A
9.999 mΩ 1 µΩ 3 V 300 A

* Subject to supply voltage conditions (see below).
Accuracy is better than ±1% from 100µΩ to 100µΩ if the maximum
possible current is used. If lower currents are used, the following table
applies:
Current Error
2 A* 5.6% + 100 µΩ
5 A* 2.6% + 40 µΩ
10 A 1.6% + 20 µΩ
20 A 1.2% + 10 µΩ
50 A 0.8% + 4 µΩ
100 A 0.7% + 2 µΩ
200 A 0.7% + 1 µΩ
400 A 0.6% + 0.5 µΩ
600 A 0.6% + 0.3 µΩ
*It is not possible to select a current less than 10 A but since the open
circuit terminal voltage is somewhere between 2 V and 5 V (if input power
is 100 V to 250 V), actual test current can be as low as 2 A when loop
resistance is 1 Ω. If actual current is less than 2 A a ‘Current loop fail’ will
be reported.
