1.0 IN GENERAL The MPPV340 model (strain gauge input) is an instrument with a 16 bit analogue to digital converter; it is made in 48x96 standard body. The MPPV model can be requested specifying the sensibility range: 1 mV/V (0.5 ÷1.5 mV/V) 1.5 mV/V (1 ÷ 1.5 mV/V) 2 mV/V (1.5 ÷ 2.5 mV/V) 3 mV/V (2.5 ÷ 3.5 mV/V) 10 mV/V (9 ÷ 11 mV/V) The MPPV340 model 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. •...

LEDS DESCRIPTION TERMINAL BOARD DESCRIPTION - analogue reference - signal input - power supply for transducer - 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 reset) -instrument power supply

2.0 INSTALLATION NOTES 2.1 SIMPLIFIED INSTALLATION PROCEDURE 1- Connect the instrument as follows: pag 6 – base instrument wiring diagram pag 7, 8 – alarm wiring diagram (if requested). 2- Use sensibility or sample weight calibrating in according with the following paragraphs. 2.2 CALIBRATING THE INSTRUMENT WITH CELL SENSIBILITY To follow this procedure you must know the cell sensibility (see it in the calibrating certificate). Suppose to have a load cell with a sensibility of 1.9856 mV/V with a full scale of 150 Kg. To calibrate the instrument do the following: 1. Power on 2. 3. 4. 5. 6....

MPPV340 M6 2.3 CALIBRATING THE INSTRUMENT WITH SAMPLE WEIGHT OR 5° WIRE If you don’t know the sensitivity of the cell, you can calibrate the instrument with a sample weight or the cell’s 5° wire. If you have a cell with about 2mV/V sensitivity and use a 1.5678Kg (or 5° wire) weight to calibrate the instrument. To calibrate the instrument do the following: 1. Power on 2. Setup the decimal point position to 0.0000 by d.p. 3. Set SEL.C = PESO 4. Exit the program menu and perform a reset display...
