Description

Type DDSY666 Single phase electronic prepayment watt-hour mete(hereafter is the meter) is the most advanced type instrument developed byus adopted the newest technique of personal computer and electronic andcurrency IC card for purchasing electric energy media. lt is assisted byof computer automation management fosoftware and hardware techniguegetting electric energy feefor measuring active energy irelectric net with Single Phase AC 50 Hz/60Hz. The meter must be mountedin the place which temperature is in -10C~+50C and the relativehumidity shall not exceed 85% And the air should not include corrosivegas, keep away from dust and sand, mildew and insect, etc.

In the column of Rated Current , the value before the bracketis basic current value lb, and the value in the bracket is the maximumcurrent Imax.

All circuits to the meter case can endure impulse voltage of 1.2/50uswaveform and 6KV peak value. In different electrode to be tested 10 timesthe meter shall not discharge or breakdown.

All the circuits to the insulation to the earth can endure alternating current

voltage 2KV of 50Hz factual sine wave in a minute.

The meter can be installed and used after being test and sealed withletterpress printing. Without letterpress printing or storage time is too long.the meter must be reset

The meter must be installed ventilate and arid place. The meter baseboard must be on the wall of fire resistance and uneasily shaken. Themeter must be installed vertically and the gradient shall not exceed 1degree. The installation height is about 1.8 m.

The meter must be installed in the protective box in the dusty place or

against possible mechanical injury.

Connection must accord with the above drawings or the drawings inthe extended cover to use brass conductor to input to avoid that the meter

shall be burnt due to loose contact.

In the too much thunderstorm place to take measures to avoid lighting injury.

The load capacity of the meter is between 0.05lb~lmax(Direciconnection) or 0.02lb ~lmax(connection through transformer). If thecapacity exceeds above the register shall not be accurate or the currentcoil shall be heated and burnt.

The meter start to work by open account Card. You must take your card toPower Management Dept. for buying credit. The Power Management Deptwill record your bought credit to your card after encrypting through MIS.

Make arrow direction of the card surface with gilded contact toward the

meter plug, insert the card into the meter.

As the card inserted into the bottom completely, after 3 seconds, the meter

display screen will show the following information

The meter is disturbed casually. Take the card out and insert it, try it

again and again.

The card is not used for this meter, or not IC card

As the meter works normally, the remain credit will be decreased, thecumulative energy will increase, and the show precision is 0.01kWh

The meter do not need standby battery, adopting all solid state IC technica

protection data so that it can keep well for more than 100 years.
