Product Detail

Model No.: YH 511

0.4A Current Protective Digital Insula

0.4A Current Protective Digital Insulation Tester Max AC 250V Overload Protective

Quick Detail:

Complies with IEC/EN 61010-1 1000V CAT III , 600 V CAT IV.

1000V DC Voltage, 750V AC Voltage(TRMS).

6600 Count(except for capacitance, temperature, insulation).

When the input terminals is V and COM, The overload protective voltage is up toAC 250 V (TRMS) ;When the input terminals is mA and

COM, protective Current is 0.4A; when the input terminals is Hi and Lo , The overload protective voltage is 600V.

Batteries:Four AA batteries (NEDA 15A or IEC LR6) Meter use 1000 hours; Insulation test use: Meter can

perform at least 1000 insulation tests with fresh alkaline batteries at room temperature.

These are standard tests of 1000 V into 1 MΩ with a duty cycle of 5 seconds on and 25 seconds off.
