1.0 GENERAL POINTS The instruments of the MPA and MPV series in the P6 type container (75mm depth) can be ordered with the ammeter type scale (MPA) or the voltmeter scale (MPV) for D.C. or A.C. input. The main characteristics are as follows: • two alarms with exchange relay output • 14V not regulated for 2 wire transducer power supply • alarm programming and 6 key calibration on instrument front panel for ease of use • 9999 point display • the 'hold' function operates directly from the terminal board ( with memory of value displayed ) and ' tara recovery ' (automatic zeroing). • possibility of...

Touch the zero key. The display will visualize the value which it keeps in memory with the first left hand digit Touch the " ^ " key to move the flashing flashing value. Confirm the programmed number by To program the decimal point observe the following indications. Touch the ^ key with the instrument in measuring mode. A decimal point will light up. In order to move this point touch the indicated key until the desired 2.3 RECOVERY TARA FUNCTION For "Recovery Tara" we mean a function that when in use zeroes the instrument readings. The Recovery Tara function with terminals 25 and 27 open is not...

MPA MPV SW P5.00 mect s.r.l. parameters ISL, FSL and OFFS. At the moment when the terminals 25 and 27 are short circuited zero is displayed and the reading zeroed. This operation is indicated when the led 'Reset' lights up on the instrument front. Let us assume that the instrument, linked to a transducer, indicates a 100kg number. Shutting down the connection between terminals 25 and 27 will zero the instrument reading , thus rendering the indications negative for weight values that are less than 100 Kg and positive for values that are greater than 100 Kg. N.B. The “reset display” function clears...
