1.0 IN GENERAL The MPA model (current input ) and the MPV model (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 or opto-isolated serial...

Press + I • keys to enter menu. To reach a menu item, use the and the key as shown in the menu flow for base instrument and base + option instrument. To change a digit, use the Wl'p' key to increment the blinking digit and the key to shift the blinking digit and confirm by ^W key. To select an item use the key and confirm by the key To go to an upper level, use the Prmt key. To exit menu, use the WW key: the modified parameters are stored.
