Product Features
◆The Portable Resistance Tester offers multiple voltage outputs: DME2305 (250V/500V/2500V/5000V) and DME2306 (5000V/10000V), with a resistance measurement range up to 0~400GΩ.
◆Dual-mode insulation resistance display. The analog pointer allows easy observation of insulation resistance variation range, while the digital display provides precise measurement results.
◆Equipped with embedded industrial MCU and real-time operating software system. High automation and strong anti-interference capability. The instrument automatically calculates absorption ratio and polarization index without manual intervention.
◆User-friendly interface with power-loss protection for measurement results. Can continuously store up to 19 measurement records. ◆When the instrument generates high voltage, an audible alert sounds with corresponding display indication.
◆Built-in residual high-voltage discharge circuit automatically discharges residual high voltage from the tested equipment after measurement. ◆Dual AC/DC power supply, equipped with rechargeable batteries and AC adapter.
◆Portable design for convenient field operation. ◆High-voltage short-circuit current ≥3.5mA, making it an ideal instrument for measuring insulation resistance of large transformers, instrument transformers, generators, HV motors, power capacitors, power cables, and lightning arresters.
