50/60 Hz Mains Frequency Rejection
SW1 6
60 Hz
50 Hz
(4)
The filter increases rejection at mains frequency disturbance, and stabilises reading,
reducing measurement noise. It is preferable to always keep the filter ON, except in cases
where maximum response speed is required.
SHUNT DETECTION
SW1 8
YES
No
(5)
It entails an injection of current of less than 3 A, which can degrade the instrument's
precision, and applies to the inputs leading to terminals M2 and M3.

They are inversed output scales, for which the fault is represented by the lower extreme.
OVER-RANGE (*)
SW2 4
YES: a 2.5% over-range value is acceptable;
a 5% over-range value is considered a malfunction.
NO: the malfunction alone causes a 2.5% over-range value.
(*) See the table below for the corresponding values
