Pollin ELECTRONIC D830632D Programmable Digital Voltmeter Instructions

Programmable Digital Voltmeter
Please read through the manual
before installment and operation

Chapter 1. General Introduction

This series digital display meters are a new generation of programmable intelligent voltage meters, which are mainly used in the real-time measurement and indication on AC or DC current in an electric circuit .With features of high  precision, good stability, calibration-free long-termoperation and onsite parameter setting on a panel, it is an idea substitute of traditional dial instrument or ordinary digital instrument.
This series of meter features a modular design by utilizing large-scale integrated circuit, high-performance single microprocessor, digital signal processing technology and SMT techniques. The calibrating potentiometer inside the meter is  cancelled and soft calibration is adopted instead. The modular and uniform design mode substantially reduces the production costs of the meter , which makes it highly cost-effective.

Chapter 4. Installment and connection

1. Shape and cutout hole dimension (unit: mm)
   Shape| Panel dimension| Case dimension| Cutout hole dimension
   ---|---|---|---
   W| H| W| H| D| W| H
   120x120square| 120| 120| 110| 110| 80| 112| 112
   96x96square| 96| 96| 90| 90| 80| 92| 92
   80x80square| 80| 80| 74| 74| 80| 76| 76
   72x72square| 72| 72| 66| 66| 80| 68| 68
   48x48square| 48| 48| 44| 44| 70| 45| 45

2. Method of installation
   Choose the corresponding hole cutout dimension from the table above , make a hole in the installation screen, insert the instruments into the hole, place the two clamping pieces into the clamping holder and push and tighten them by hand.

3. Terminal arrangement and function declaration of instrument(please accord to the one of instrument case) 3. 1Auxiliary power supply (POWER): The voltage range of operation is AC 220V,50/60Hz. It is suggested to install a fuse of 1A beside of the live wire when using the AC power supply to prevent damaging the instrument. In the areas with poor power quality, the surge suppressor and quick pulse group suppressor should be installed in the power supply circuit.
   Electrical quantity signal input (I input ):HI represents “+”port of DC input signal, live wire terminal of AC voltage input signal and inlet wire terminal of AC current input signal. Input voltage should not be higher than the maximum value (AC 600V, or you should consider of using PT and installing fuse of 1A on voltage input port. While the current is higher than AC10A, you should consider of using CT)
   3.2 Typical connection
   

Chapter 5.Cautions

1. Please confirm if the power supply, input signal and each terminal wiring of the meter are correct and reliable before applying the power.
2. The instrument must be preheated for 15 minutes to guarantee the precision of measurement.
3. The instrument should not be rapped, knocked and vibrate excessively and its using environment should meet the technical requirements.
4. The meter has been calibrated according to the measuring range required by the customer upon order. The user should check once again if the measuring range of the meter is fit with the specifications of the transformer and set the measuring range again if not.

Chapter 6. Packing and Storage

The instrument and accessories with packing should keep storage conditions cool and dry and free of wet and corrosive gas with temperature not more than 70°Cand not less than -40°C,and relative humidity85%RH.

Appendix 1 : Example of programming
Example 1: The factory default parameter is AC 0-600V(PT=1); If the voltage transformer is5KV/100V should modify the PT multiplying power as 50(5000/100)
Example 2: The factory default parameter is AC 0-600V(PT=1); If the voltage transformer is8KV/100V should modify the PT multiplying power as 80(8000/100)
Example 3: The factory default programmable password is 0000 modify the password as 1234,
Return upon error password
