1. Resistant to high-density neoprene material, the megohmmeter has a built-in digital insulation system to ensure that you can get a good air resistance test.
2. The megohmmeter has a digital LCD meter, which can read all the data clearly
3. Adopt low-loss high-rate inductive energy storage DC voltage converter, which can convert 12V voltage into 250V/500V/1000V DC voltage. It uses a digital lcr bridge for resistance measurement and insulation resistance testing.
4. Accurate and reliable, large LCD display, strong anti-magnetic and anti-interference function.Wide measurement range, backlight display, test lock, automatic shutdown (only applicable to the maximum dc1000v output function) and other functions.
5. It is used in the field of insulation resistance testing of motors, cables, electromechanical equipment, telecommunication equipment, and electric facilities.

Parameter:
1. Output voltage: 250V/500V/1000V basic accuracy +/-10%
2. Short circuit current: less than 1.6mA
3. Test current: 250V(R=250kΩ) 1mA/500V(R=500kΩ) 1mA/1000V(R=1Ω) 1mA ±10%
4. Measuring range Insulation resistance:
-250V: 0.1MΩ-20MΩ/500V: 0.1MΩ-50MΩ/1000V: 0.1MΩ-100MΩ +/- (4% of reading +/- 2 units)
-250V: 20MΩ-500MΩ 500V: 50MΩ-1000MΩ/1000V: 100MΩ-2000MΩ +/- (4% of reading +/- 2 units)
5. Median resistance: 250V/500V: 2MΩ 1000V: 5MΩ
6. Voltage measurement: AC750V +/- (1% reading + 6 units)
7. Plug position: Insulation resistance: L.E AC750V: ACV G
8. AC750V input resistance: 1MΩ, AC750V frequency response: (50~200) Hz
9. Note: Median resistance—the lower limit of resistance measurement to ensure that the voltage across the measured terminals is not lower than 90% of the nominal value of the test voltage.
