In DC mA function, neither in AC nor DC+AC selection, loop-current percentage (
%4-
20mA
) reading is displayed simultaneously. It is set at 4mA = 0% (zero) and 20mA =
100% (span) with 0.01% high resolution for testing and monitoring externally powered loop
current in industrial process control applications.
*Note: When measuring a 3-phase system, special attention should be taken to the phase-
to-phase voltage which is significantly higher than the phase-to-earth voltage. To avoid
exceeding the voltage rating of the protection fuse(s) accidentally, always consider the
phase-to-phase voltage as the working voltage for the protection fuse(s).
