2. Turvallisuustiedot

Always adhere to safety precautions when using electrical testing equipment. The IRT803 is designed with safety in mind, featuring a CATIV rating up to 600V and CATII up to 1000V, ensuring protection in various jobsite environments. Failure to follow safety instructions can result in electric shock, fire, or damage to the instrument.

• Älä käytä testeriä, jos se näyttää vaurioituneelta tai jos mittausjohdot ovat vaurioituneet.
• Varmista, että oikea toiminto ja mittausalue on valittu ennen mittausten tekemistä.
• Always disconnect power to the circuit under test before connecting or disconnecting test leads for resistance measurements.
• Käytä asianmukaisia ​​henkilönsuojaimia, kuten eristettyjä käsineitä ja suojalaseja.
• Do not operate the tester in wet conditions or in the presence of explosive gases or dust.
• Vaihda paristot viipymättä, kun heikon pariston varoitusvalo tulee näkyviin, jotta mittaustulokset ovat tarkkoja.

5. Asennus

5.1. Akun asennus

The IRT803 requires four (4) AA batteries for operation. To install or replace batteries:

1. Varmista, että testeri on sammutettu.
2. Paikanna paristolokero laitteen takaosasta.
3. Avaa paristolokeron kansi ruuvimeisselillä.
4. Aseta neljä AA-paristoa paikoilleen ja huomioi oikea napaisuus (+/-) lokeron sisällä olevien merkkien mukaisesti.
5. Sulje paristolokeron kansi kunnolla.

5.2. Testijohtojen liittäminen

Connect the test leads to the appropriate input jacks on the tester. For most measurements, the red lead connects to the 'V Ω INSULATION' jack and the black lead connects to the 'COM' (common) jack. Ensure connections are firm and secure.

6. Käyttöohjeet

6.1. Powering On/Off and Display Backlight

• To power on the unit, rotate the selector dial from 'OFF' to any desired measurement function.
• To power off, rotate the selector dial back to 'OFF'. The unit also features auto power-off to save battery life after a period of inactivity.
• Paina VALITSE button (often indicated by a light bulb icon) to toggle the display backlight on or off.

6.2. Eristyskestävyystestaus

The IRT803 can perform insulation resistance tests at various voltages.

1. Valitse testimäärätage: Rotate the selector dial to the desired insulation test voltage (50V, 100V, 250V, 500V tai 1000V).
2. Kytke mittausjohdot: Connect the red test lead to the circuit under test and the black test lead to the ground or common point. Ensure the circuit is de-energized.
3. Aloita testi: Press and hold the large red TESTATA button to begin the insulation test. The test voltage will be applied, and the resistance reading will be displayed.
4. Lukitustoiminto: For continuous testing, press the LUKKO button after initiating the test. This will maintain the test voltage without needing to hold the TESTATA -painiketta. Lehdistö TESTATA uudelleen lukituksen avaamiseksi.
5. Compare Function: Käytä VERRATA button to set a reference value and compare subsequent readings against it.
6. PI/DAR-testi: Select the PI/DAR function on the dial. The meter will automatically perform the Polarization Index and Dielectric Absorption Ratio tests, displaying the calculated values.
7. Read and Record: Observe the reading on the LCD. Use the PIDÄ button to freeze the display for easier recording.
8. Purkaus: After completing an insulation test, the circuit under test should be discharged. The IRT803 typically handles this automatically, but always exercise caution.
