Running with no-load<\/strong>
\nAs no current in the circuit and the voltage value is 115% of the rated voltage,the testing output no more than one impulse.<\/p>\n

 <\/p>\n

Insulation performance<\/strong>
\nAll circuit interval of the meter can withstand impulse voltage with waveform 1.2\/50\u03bcs,leak value 6KV,and it can not occur electric arc or rout as it is tested at the same pole.
\nAll circuit insulating earthing of the meter can withstand AC voltage 4 KV with actual sine wave 50Hz or 60Hz and it can withstand 1 minute.<\/p>\n

Working voltage limit:80\uff5e120% Ub<\/strong><\/p>\n

Installing and using:<\/strong>
\n1\u3001 The meter can be installed and used after being test and sealed with letterpress printing.Without letterpress printing or storage time is too long the meter must be reset.
\n2\u3001The meter must be installed ventilate and arid place.The meter base board must be on the wall of fire resistance and uneasily shaking. The meter must be installed vertically and the gradient shall not exceed 1.The installation height is about 1.8m.
\n3\u3001 The meter must be installed in the protective box in the dusty place or against possible mechanical injury.
\n4\u3001Connecting must accord with the above drawing or the drawing in the extended cover.Use brass conductor to input to avoid that the meter shall be burnt due to loose contact.
\n5\u3001 In the too much thundersrorm place to adopt measures to avoid lighting injury.
\n6\u3001 The load capacity of the meter is between 0.05Ib\uff5eImax(Direct) or 0.02Ib\uff5eImax(with transformer).If the capacity exceeds above the register shall not be accurate or the current coil shall be heated and burnt.<\/p>\n

 <\/p>\n

 <\/p>\n

Transport and storage:<\/strong>
\n1\u3001 Transport and storage of the meter must not be shaken and must accord with IEC62053-21 IEC62052-11.
\n2\u3001 The meter must be stored in the original packing box and the environmental temperature is in-40\u2103~+70\u2103.Relative humidity shall not exceed 95%.And There isn’t any corrosive gas.The environmental temperature shall not vary violently.
\n3\u3001 The meters should be in the original packing box and the boxes should be piled up no more than five on the rack.The separate meter is not suitable for storage.<\/p>\n

Deadline of guarantee:<\/strong>
\nWithin 24 months from the date of manufacture the user complies with all of above rules.If the meter still being sealed or does not conform to any technical requirements of IEC62053-21 IEC62052-11 or of any certification of power department or measuring department.
\nThe manufacture guarantees to repair freely or to change.<\/p>","protected":false},"excerpt":{"rendered":"
