1.0 IN GENERAL The MPO model (ohm input ) is an instrument with a 16 bit analogue to digital converter; it is made in 48x96 standard body. The MPO instrument can be requested with fixed scale, with five selectable scales (MPO347 100) or 20 with µ26 option (temperature compensation). The MPO 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. The MPO instrument can be requested with the following options: • mono-directional...

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...

2.0 INSTALLATION NOTES 2.1 SIMPLIFIED INSTALLATION PROCEDURE 1- Connect the instrument as follows: pag 7 – base instrument wiring diagram pag 8 – input signal wiring diagram pag 9, 10 – alarm wiring diagram (if requested). 2- Power up the instrument 3- Front panel keys allow the following set up: • With the d.p. key is possible to change the decimal point position. To set up the decimal point position, press the relevant key (it appears “000000”) and use the key to shift the decimal point in the desired F . .S position. When the decimal point is correct, confirm by the • With the key it is possible...

• To lock the front keys or to use other configuration, see the “ Front key enabling” paragraph • The instrument is ready to be used • To use the instrument with the “display reset” function, see "display clear function" paragraph 2.2 COMPLETE INSTALLATION PROCEDURE Follow this procedure to completely set up the instrument. 1. Look at the following table to change the input and peak hold values 2. To set the alarm set-point parameters see “ALARMS” paragraph ( for window alarms, delay and hysteresis ) 3. For analogue output set up see “ANALOGUE OUTPUTS” paragraph 4. For serial output set up see...
