1.0 GENERAL POINTS The instruments of the MPP series in the P6 type container (75mm depth) use the potentiometer tranducer. The main characteristics are as follows: • two alarms with exchange relay output • 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 programming delay time and hysteresis alarms using hidden menu which is password protected. • possibility of fixed zero setup •...

See the paragraph "Instrument Setup". There now follow examples of zero calibration which are also true for end scale and alarms using the personalized keys F.S., SET1 and SET2. 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...

MPP P6 mect s.r.l. 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 in use and in these circumstances the instrument reading is linked to the programming 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 100mm number. Shutting...
