Test probe, VK701
[-> Main menu -> F5: System administration -> F5: Setup -> F5: More -> F2: Test probe, VK701]
The Unimet test probe or connected test adapter (e.g. VK701 for testing extension cables)
must be zero-balanced. As with an ohmmeter, this ensures that the ohmic resistance of the
test adapter and test probe will not affect the PE conductor test result. The test adapter cables
need to be as short as possible.
UNIMET® 1100ST saves the calibration values. You should repeat this calibration procedure
every time you connect a different test probe or a different test adapter to the test system.
Note: For information about general device calibration, see “Calibration” on page 81.
