Linear Resistance Measurement Unit ResTest 55

New

Product ID: 3799

ResTest 55 is specially designed to measure both multicore cables and smaller sections.

Description:

Compacting jaws:
- Drastically reduce contact resistances between wires.
- Ensure good distribution of the current.
- Key factor for precise and reproducible measurements.
Self-cutting knives:
- Equipped with an LED-based contact monitoring system.
- Enable safe and efficient use with insulated cables.
Integrated system:
- Includes a ruler with calibrated length.
- Temperature sensor for accurate linear resistance value (Ω/km @ 20ºC).
- Offers operating comfort and mastery of measurement uncertainties.
AESA specification:
- Specifies the overall accuracy of the measurement, not just the micro-ohmmeter.

Key Features:

Compatibility:
- For both small conductors and multicore cables.
- Suitable for very fine wires up to 50 mm² (1/0 AWG) conductors.
Conductor Types:
- Class 1 (rods & wires).
- Class 2 (stranded conductors).
- Class 5/6 (flexible conductors).
- Sector-shaped conductors.
- Insulated conductors.
- Multicore cables.
Enhanced Comfort:
- Self-cutting knives for both voltage and current contacts.
- LED monitoring system.
- Interchangeable jaws.
Ease of Use:
- Direct readings in Ω/km @ 20ºC.
- Button or touchscreen interface.
- Embedded PC.
Overall Accuracy:
- Specifications related to the entire measurement system, not just the instrument.
