KD305Y Insulation Resistance Tester is a portable tester controlled by a single-chip microcomputer. It offers multiple output voltages, large charging current (＞5mA), automatic discharge and data storage, with high anti-interference ability and accurate measurement for large-capacity capacitive loads.

1. Multiple DC output voltages (500V/1000V/2500V/5000V/10000V) to meet diverse testing needs.
2. Automatically calculates and displays R15S, R60S, R600S, absorption ratio and polarization index.
3. Short-circuit current ＞5mA for accurate testing of large-capacity capacitive loads.
4. Automatic range switching, fast discharge after testing and residual voltage display for safety.
5. Measures AC/DC voltage up to 600V with IP65 (lid closed) and IP40 (lid open) protection.
6. Built-in large-capacity lithium battery, AC/DC dual-use with overcharge and undervoltage protection.
7. Automatic timing (max 600S) with buzzer prompts and stores historical test data with time stamps.
8. Strong anti-interference ability, stable readings and complete protection functions for safe operation.
