This product is KT65DL electrical test instrument from Kewtech company. It can test electrical connection, electrical insulation, loop impedance etc.
This manual covers safe operation and features of the KT65DL, including continuity, insulation resistance, loop impedance, and RCD testing. It includes safety warnings, instrument layout, and detailed measurement specifications for each function. The device incorporates Anti Trip Technology (ATT) to bypass RCDs during loop impedance tests. Accessories and memory functions are also described.
| Continuity Accuracy | 0~0.19Ω ±0.1Ω, 0.2~2000Ω ±(2%rdg+8dgt) |
|---|---|
| Insulation Resistance Accuracy | 0~19.99MΩ ±(2%rdg+6dgt), 20~200MΩ ±(5%rdg+6dgt) |
| Loop Impedance Accuracy | 20Ω ±(3%rdg+4dgt), 200Ω ±(5%rdg+15dgt), 2000Ω ±(3%rdg+8dgt) |
| Earth Resistance | Measures Zs tables for fuses and circuit protection |
It supports eight functions: continuity, insulation resistance, loop impedance, prospective short circuit current, RCD, voltage, phase rotation, and earth resistance.
The instrument is designed for a maximum line-to-earth voltage of 300V 50/60Hz.
The rated voltage for L-PE (ATT) is 100~260V 50/60Hz.
The accuracy is ±(5%rdg+6dgt).
