1.0 IN GENERAL The MPA 386 model (alternating current input ) and the MPV 376 model (alternating voltage input ) are instruments with a 16 bit analogue to digital converter; they are made in 48x96 standard body. The MPA and MPV models have interesting features as: • 4 ½ digit display ( ± 19999 digits ); • set-up of any reading value with any input value in the requested range; • maximum or minimum peak-hold; • programmable digital filter; • display reset function. The MPA and MPV instruments can be requested with the following options: • mono-directional or bi-directional (RS232 or RS485) standard...

LEDS DESCRIPTION TERMINAL BOARD DESCRIPTION - analogue reference - signal input - power supply for transducer ( V5-=-V24 option) - analogue outputs (if requested) - Hold : short-circuiting terminals 10/12 stores observed - Display reset. Terminals 11/12 open: the reading are the same as the programming values. Terminals 11/12 closed: at the moment the terminals are short-circuited the display becomes zeroed (display -instrument power supply
