Conductor resistance jig
A. The instrument
This fixture with bridge, it can greatly reduce the error between the measured and clamp with two sets of change chuck and a pair of miniature terminal,
Current end shape is rectangular shape tiger mouth, can make the current client contact with good sample, made the current uniform distribution in the tested wire core, reduced
Influence on measuring contact resistance; Suitable for measuring the round wire, wire, the fan line dc resistance of a conductor, can also be attached to the terminal measurement
All kinds of enameled wire under 0.1 mm.
2. Standard
In line with the GB3048.2, 5013, GB5023 GB3048.4, GB, IEC 60245-2, IEC 60227, IEC 60468 and other requirements.
3. The main parameters
Measure the wire length: 1 m
The maximum measured section: 120 was (0.5 ~ 12 mm) diameter:
Current terminal and voltage side span: 60 mm
