Extension Cable
The complex nature of Hall-effect measurements makes it necessary to match extension cables to the probe when longer
cables are needed. Keeping probes and their extensions from getting mixed up can become a problem when more than
one probe is in use. The Model 475 alleviates some of the difficulty by allowing users to match probes to extensions in
the field. Stored information can be viewed on the front panel and read over computer interface to ensure proper mating.
NOTE: Calibrated probe and extension cable pairs may be purchased from Lake Shore and are recommended for the
best accuracy. Extension cables with no calibration may also be used. The Model 475 can then be used to match a probe
to the un-calibrated extension cable.
To match a probe with an extension cable, verify that the probe is connected to the instrument. To begin the matching
process, press and hold the Probe key for approximately 4 seconds. The following screen appears as a prompt for
selecting the programming method.
