6.- EQUIPMENT MAINTENANCE
In view of the special characteristics of the equipment, this MAY ONLY BE
REPAIRED BY AUTHORIZED TECHNICAL PERSONNEL . As
mentioned in other sections, because of the special danger involved in
handling high voltages with the equipment, the maintenance personnel
repairing, adjusting and calibrating the equipment should be duly qualified
and trained.
Opening of the equipment by non-authorized personnel implies cancellation of the
warranty period.
The equipment does not contain any internal elements to be handled by
the operator, and
SHOULD IN NO CASE BE OPENED, DUE TO
THE SERIOUS DANGER OF ELECTRICAL SHOCK .
The maintenance of the equipment is very straightforward and consists simply of
keeping it in good condition externally and making sure the cables supplied are also in good
condition. If the fuse blows, it should be replaced with one of identical characteristics, as
described in section 6.4 (Replacement of fuses). If a fuse should blow continuously, the
equipment should be sent for repair (see section 8.1: Return for calibration/repair).
In order to maintain its values of accuracy, the equipment should be calibrated at
least once a year.
Special care should be taken to prevent the unit from getting wet, and it should be
protected against rain if necessary. In the event of extreme levels of humidity or
temperatures outside the margins, the measures provided by the equipment will not be valid,
and it will be necessary to wait for the equipment to regain its operability. For example,
leave it to dry if it has got wet. Likewise, changes in the situation of the equipment,
especially if stored, may cause rapid variations in temperature causing humidity to appear as
a result of condensation.
