IN GND Vpot REC.t. HOLD DGND Gnd/220/110/24 TERMINAL BOARD DESCRIPTION - instrument power supply (Vcc, Vpt, 24Vac, 110Vac, 220Vac); if power supply “Vcc” the terminal 7 = GND Terminals 1, 2 - input measure (terminal 2 = gnd) Terminal 3 - potentiometer power supply (2,0V) Terminal 5 - Hold: shortcircuiting terminals 5 and 6 will memorize the reading Terminal 4 - Recovery tara: 1) Terminals 4 - 6 open: the reading is the same as the programmed values 2) Terminals 4 - 6 closed: at the moment the terminals become shortcircuited the display is zeroed (rec.tara) 2) Connection for 2 wire transducer...

Connection for potentiometer input 2.0 INSTALLATION NOTES 2.1 INSTALLATION PROCEDURE 1- Individuate the type of instrument reading on the label the item “prodotto” and use the relative wiring diagram 2- Switch on the instrument 3- Use the zero key to set up the value that must coincide with the minimum input value (beginning scale of the instrument). 4- Use the “FS ↵“ key to set up the value that must coincide with the maximum input value (full scale of the instrument). 5- Use the d.p. key to set up the decimal point as required 6- to execute the set up with the dedicate keys see paragraph “How...

mect s.r.l. 1st OPERATION Touch the zero key. The display will visualize the value which it keeps in memory with the first left hand digit flashing. 2nd OPERATION Touch the “4zero” key to move the flashing number to the right. 3rd OPERATION Touch the “5d.p.” key to increase the flashing value. 4th OPERATION Confirm the programmed number by touching the ' FS ↵' key. To program the decimal point observe the following indications. ME2063_05 12/11

mect s.r.l. Touch the “5d.p.” 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 point is reached and than confirm with “FS ↵“ 2.3 RECOVERY TARA FUNCTION For “Recovery Tara” we mean a function that when in use zeroes the instrument readings. The Recovery Tara function can be enable from “Reset / Exit” key or shortcircuiting terminals 4 and 5. At the moment when the terminals 4 and 5 are short circuited or “Reset / Exit” key is pressed, zero is displayed and the reading zeroed. This operation is indicated...
