WM12 DIN and WM12 96 are general purpose multi func-

tion meters that allow to monitor all the mains parameters

of an electrical line or load. The compact housings com-

bined with a complete selection of measurements allow the

instruments to be mounted in all the switch and control

gears as local indicators, instead of the classical single

function analogue or digital panel meters.

The unit is provided with some unique installation visual

status functions like:

• the window control of the mains 3-phase voltage

notifying the user at a glance if the mains is supplied

out of the requested power supply tolerance,

• the neutral current control showing immediately anyload

or installation anomaly due to high harmonic distortion

or load insulation loss (high earth leakage current).
