Preparing for first-time use
Delete all
This menu item deletes the complete measurement memory of the device.
By performing this function, all records on the device will be irrevo-
cable deleted!
New firmware
This menu item is needed for future firmware updates, if there are changes
in the standards or device software enhancements.
Information and updates are made available on our internet site
www.testboy.de.
Visual inspection
When the visual inspection function is activated, a query is made that has to
be confirmed with a key press before the device test is carried out. The test
is terminated if "No" is selected.
Test lead compensation (LtgKompensat)
This function allows the test leads to be compensated for. This prevents the
resistance of the test leads influencing the measurement results.
In order to carry out the compensation, connect one test lead to the socket R
and measure to the grounded contact of the DUT (device under test) socket.
Press the "Save" key to store the value in the device.
When the test leads are changed, the test lead compensation should be re-
peated.
