BTMETER BT-6688B Megohmmeter 200 Gig Ohm Digital Insulation Resistance Tester, 500V/1kV/2.5kV/5kV Test Voltage, Auto Ranging, Backlight Display

BTMETER BT-6688B Megohmmeter 200 Gig Ohm Digital Insulation Resistance Tester, 500V/1kV/2.5kV/5kV Test Voltage, Auto Ranging, Backlight Display

Q: What's the accuracy of this insulation resistance tester?

Base on their manual, it says 1m～200m ohm: +/- 3.0%+5, 200m～10g ohm: +/- 5.0%+5, 10g～200g ohm:+/- 10.0%+5

Q: For the BT6688B insulation resistance tester, what is the test current for resistance measurements at rated voltages?

Do you mean what is the maximum current it can push if the resistance is very low? If not, the answer to this question will vary depending on which voltage setting you use and the resistance of the system you are testing. If for example, you test using the 1000v setting on a cable that has 2G-OHM resistance, the current is 1000 / 2,000,000,000 = .5 uA.

Q: Can it measure polarization index measurement (pi) and dielectric absorption ratio measurement (dar)?

Yes, Both require a megaohmmeter, You just have to follow the correct sequence /procedure
