Wiring modum et test gradus de voltage sustinere testem

The so-called withstand voltage tester, according to its function, can be called electrical insulation strength tester, dielectric strength tester, etc. Its working principle is: apply a voltage higher than the normal working voltage to the insulator of the tested equipment for a Certa tempus, et voltage applicantur in ea non solum producere parva leakage current, ita et Nulla est melius. In test ratio est composito ex tribus modules: Program imperium potentia moduli, signum acquisition et condiciones moduli et computatrum imperium ratio. Select Duo Indicatores de voltage Tester: Magna output intentione valorem et magnam metum current valorem.

Wiring modum sustinere voltage tester;

I. Reprehendo et confirmare pelagus potentia switch resistere voltage testter in "off" positus

II. Praeter specialem consilio instrumenti, omnes uncharged metallum partes debent esse firmissime

III. Coniungere fila et terminals omnium virtutis initus terminals de probata apparatu

IV. Close omnis potentia virgas, relationes, etc. ex probata apparatu

V. Adjust in test intentione resistere voltage tester ad nullus

VI. Iungo altum voltage output linea (plerumque rubrum) de voltage tester ad virtutem initus in probata apparatu

VII. Coniungere circulum grounding filum (plerumque nigrum) de resistere voltage tester aditus invitus imminhirged metallum parte apparatu sub test

VIII. Propinquus pelagus virtus switch de resistere voltage testter et tardius auget secundarium intentione de testes ad requiritur valorem. Plerumque, in boosting celeritate non excedat D v / sec

IX. Ponere in test intentione ad certum tempus

X. Tardus in test intentione

XI. Averte pelagus virtus switch de resistere voltage tester. Disconnect altus voltage output linea voltage problems primum et circuitus terra filum voltage tester

In his conditionibus indicant quod probata apparatu non transiet in test:

* Cum in test intentione non oriri ad certum intentione valorem vel voltage guttae pro

* Cum voltage tester habet monitionem signum

Notandum quod ex periculo altum intentione in resistere voltage test, speciale cura debet esse in test.

In his puncta opus speciale:

* Non debet esse certa, quod solum exercitati et auctoritate personas potest intrare in test aream ut agunt instrumentum

* Fixum et obvious monitionem signa debet poni circa test aream ne aliis personas ab intrantes periculosa aream

* Cum temptationis, omnes personas, comprehendo in operator, oportet manere a temptando instrumentum et apparatu sub test

* Noli tangere output lineam test instrumentum, cum est started

Test gradibus resistere voltage tester:

I. Reprehendo utrum per "voltage ordinacione" nodum de resistere voltage tester est rotentur ad finem anticlockwise. Si non, gyrari ad finem.

II. Plug in virtute funis instrumenti et conversus in potestatem switch instrumenti.

III. Select convenientem voltage range: set in voltage range switch ad "5kv" situ.

IV. Select convenientem ac / DC voltage mensura calces: Set in "AC / DC" switch ad "AC" situ.

V. Select convenientem Leakage Current Range: Set in Leakage Current Range Switch ad "2ma" situ.

VI, Preset Leakage Current Value: Press "Leakage Current Preset SWITCH PB", posuit in "Pellentesque" positum, et adjust in "Leakage Current in Leakage Current Meter est" 1.500 "Meter. Ad adjust et switch in switch ad "test" situ.

VII. Leo Tempus occasum: set in "leo / manual" switch ad "leo" positus, adjust in leo switch et posuit eam ad "XXX" seconds.

VIII. Inserere in altum voltage test virgam in ac voltage output terminum instrumenti et coniungere ad hamo alterius nigrum filum cum nigrum terminum (terra terminatio) de instrumenti.

IX. Iungo in altum voltage test virga, terra filum et probata apparatu (si test est instrumentum, in generali nexum modum est: Nigrum in Fibulne finis finis virtutis funem obturaculum de fine finis virtutis funiculus Part, et alia finem summus intentione terminum obturaculum (l seu n). Ad mensuras partes posita insulatable in insulatable.

X. Satus in test post reprehendo instrumentum occasum et nexum.

XI. Torcular "Satus" Switch instrumenti, tardius adjust in "voltage ordinacione" Knob ut satus boosting, observe in voltmeter ad "3.00" in voltmeter. In hoc tempore, in current valorem in leakage ammeter est etiam orientem. If the leakage current value exceeds the set value (1.5mA) during the voltage rise, the instrument will automatically alarm and cut off the output voltage, indicating that the tested part is unqualified, Press the “reset” switch to return the instrument to its Originale statu. Si autem leakage current non excedat paro valorem, instrumentum mos reset statim post leo tempore, significans quod mensuras est qualified.

12use "remote control test" modum: inserere quinque core aviation obturaculum in remotis imperium test virgam in "remote potestate" test imperium in instrumento, et torcular switch (ut pressed) in temptare virgam initium. Aviation obturaculum, etiam notum ut plug tabernaculi, late in variis electrica circuits et plays partes connectens vel disconnecting circuits.
