Product Features
- AC/DC Voltage Measurement Capability: Allows verification of both alternating and direct voltage levels during insulation testing.
- USB Data Transfer Interface: Enables seamless offloading of stored test results to a PC or compatible device for further analysis and record-keeping.
- Low-Battery Indication: Built-in warning alerts the user when battery levels are insufficient to guarantee accurate readings, preventing misleading measurements.
- On-Board Data Storage: Capable of storing up to 999 individual test records internally, facilitating trend analysis and periodic maintenance tracking without needing paper logs.
- Polarization Index (PI) Measurement: Automatically computes and displays the polarization index, aiding in the assessment of insulation aging and moisture content over time.
- Dielectric Absorption Ratio (DAR) Functionality: Calculates DAR values to help distinguish between surface leakage and bulk insulation deterioration.
- Over-Range Alarm: Provides audible/visual notification if the measured resistance exceeds the instrument’s measurement range, ensuring the user is immediately aware of out-of-range conditions.
- Maximum (MAX) Display Hold: Captures and holds the peak reading during a test, allowing the user to review the highest insulation resistance value without needing to watch the display continuously.
- LCD Backlight: Illuminates the display for easy reading in low-light or dimly lit environments, improving usability on field sites.
- Comparative Measurement Mode: Lets users compare successive readings against a reference value, simplifying the detection of insulation degradation trends.
- Adjustable Measurement Time Selection: Offers configurable test durations (e.g., 1 s, 10 s, 60 s) so users can tailor the measurement period according to different insulation diagnostic standards or workflows.
