6.2.- Care of cables
The UM2B unit is capable of producing high voltages, as a result of
which THE CABLES SHOULD BE IN PERFECT ORDER, TO
AVOID THE DANGER OF ELECTRICAL SHOCK OR ERRORS
AND INACCURACIES IN MEASUREMENT.
The cables and their condition should be periodically checked in order to detect
beforehand any deterioration or breakage that might cause situations of danger for the
operators and/or malfunctioning of the equipment. If the cables are damaged, they should be
sent for repair to an authorized technical service or new cables should be acquired (see
chapter 8). This is applicable also to the cable and unit connectors.
Special care should be taken with the serial cable for connection of the PC, since it is
in charge of controlling the unit.
It is very important not to tread on or move the cables during testing,
since this might alter the measurements, especially at low current values
(very high measured resistances).
For properly measuring, the cables must be completely stretched until the
measurement point without creases, or anyway, that these have a radius
not inferior than 200 mm.
