Capabilities
- Contactless measurement arrangement with direct resistance indication
- A generator around the rail supplies the measuring signal
- A separate C-sensor measures joint current instead of using an internal shunt
- A V-sensor on the rail head measures voltage across the joint
- Separates joint current from parallel paths through impedance bonds, connecting lines, and bedding
- Store test results with joint identification in the display unit
- Backlit display and six-key touch pad
- Tester, generator, V-sensor, and C-sensor form the measurement system
- Accessories include two lithium-ion rechargeable batteries, charger, 33 Ω test resistor with probes, tester protector, transport case, and manual
