Product Details
The micro-ohmmeters VG-CS SLxx0 are used for high ohmic measurements of train loop resistances. The instruments can maintain the maximal measuring current up to 24V. All instruments are identical, except the maximal measuring current. The strengths of the instruments are the easy handling, rugged design, low weight and long measurement cables.
The 4.3″ LCD graphic display, enables measurements in darkness, coldness and full sunlight.
Designed for continuous measurements, the instruments have no limitation for the numbers of measurement cycles.
An internal thermal printer is standard to enable logging of test results.
With the option “remote logging” all stored measuring values can be downloaded to a personal computer, laptop or Android device.
Measurement data is saved directly to a USB stick. A cable remote control or a remote control dongle is available on request.
The VG-CS SL70, with a weight of 7.5kg only, is very handy and easy transportable. The rugged transport case contains all test cables and accessories.
Typical applications are ohmic tests of:
- Train loop resistances
- Lightning protection circuits
- High current busbar joints
- Cable splices
- Welding joints
- Ground connections
- Railway parts
Micro-Ohmmeter Remote Control
The remote control unit is used to control and monitor the VG-CS SLxx0-II. Integrated sense inputs enables remote controlled tests directly on the device under test. A 2-line back lighted LCD-display shows test parameters and results which can be sent to the printer. Three light emitting diodes indicates the status of the test in progress. The housing is waterproof and is specified to DIN40050/IP67.
