YCRT-D510 Digital Insulation Resistance Meter

Features and Functions

• Large 4-bit LCD display with gray backlight, adjustable for dim environments.
• Data storage: 500 groups of data with "FULL" prompt; supports USB data upload to PC.
• Multiple voltage outputs: 100V, 250V, 500V, 1000V, 2500V, 5000V, 10KV, 15KV (±10% accuracy).
• Safety compliance: IEC61010-1, IEC61557-1/5, IP54 (dust/water-resistant), CAT Ⅲ 300V.
• Built-in rechargeable 12.6V lithium battery with low-battery indicator and overload protection.
• Shockproof, dustproof, and moisture-proof structure for harsh environments.
• High-resolution measurements: Insulation resistance (0.01MΩ–10TΩ), DC voltage (0–1000V), AC voltage (0–750V), DC current (0.1nA–6mA), capacitance (10nF–50μF).
• Automatic shutdown: Powers off after 15 minutes of inactivity.

• Insulation resistance test: With step-adjustable voltage and high-voltage protection (≥6mA short-circuit current at 15KV).
• Polarization Index (PI) and Absorption Ratio (DAR) measurement: Automatically calculates PI (R10min/R1min) and DAR (R60s/R15s or R60s/R30s) for insulation performance assessment.
• DC/AC voltage test: DC 0–1000V, AC 0–750V with ±5% accuracy.
• DC current test: Range from 100pA to 6mA with multiple resolution levels.
• Capacitance test: Measures 10nF–50μF, requiring manual range adjustment.
• Ramp test (RAMP): Step-wise voltage increase (10% increments) to target voltage.
• Filter test (FR): Selectable filter times (10S–50S) to stabilize measurements.
• Data management: Lock, store, review, and delete measurements; "MR" symbol for data review.
• Alarm settings: Customizable thresholds for insulation resistance, DC/AC voltage (flashing symbol and audible alert).
• Guard terminal function: Reduces surface leakage errors in high-resistance measurements (e.g., cables).
