1. For RS2533, the maximum measurable resistance of insulation test by the instrument is 20GΩat 500V, 40GΩ at 1000V and 100GΩ at 2500V; For RS2550, the maximum measurable resistance is 100GΩ at 2500V, and 200GΩ at 5000V; For RS2565, the maximum measurable resistance is 200GΩ at 5000V, and 400GΩ at 10000V;
2. RS2533 load resistance under rated output voltage can be as low as 4MΩ/8MΩ/20MΩ; 20MΩ/40MΩ for RS2550; 40MΩ/80MΩ for RS2503, which enables the instrument to precisely measure lower insulation impedance.
3. Automatic-switching high-low dual-scale indication, colorful scale easy to read, with colors corresponding to LED display.
4. The complete machine adopts ABS plastic machine case of portable design, with strong interference resistance, compact structure and beautiful appearance.
5. The instrument adopts ultra-thin tensile silk header, with strong shock resistance.
6. AC/DC, built-in rechargeable battery and intelligent charging modules, larger complete machine output power (Model C).
7. An ideal instrument to measure the insulation resistance of power transformer, instrument transformer, generator, high-voltage motor, power capacitor, power cable, surge arrestor, etc.
