16 Miscellaneous
16.1 Instrument Storage
During day to day use the instrument can be switched off at the mains switch located above the mains socket on
the front panel of the instrument.
If the instrument is to remain unused for any length of time, it is recommended to unplug the mains lead. In
addition, it is advisable to protect this high precision instrument from moisture. It is recommended to close the lid
for storage in order to protect the device from dust and dirt.
16.2 Care and Maintenance
The Midas micro 2883 is basically service free, as long as the specified environmental conditions are adhered to.
As a result, service and maintenance is restricted to cleaning of the equipment and calibration at intervals
stipulated by the application for which the instrument is used.
The insulation of all cables should be periodically checked for damage. If any damage to the insulation is detected
then a new measuring or HV cable should be ordered from Haefely Hipotronics.
16.2.1 Cleaning the Instrument
The instrument should be cleaned with a lint free cloth, slightly moistened using mild household cleanser, alcohol
or spirits. Caustic cleansers and solvents (Trio, Chlorethene, etc.) should definitely be avoided.
In particular, the protective glass of the display should be cleaned from time to time with a soft, moist cloth such as
used by opticians.
16.2.2 Instrument Calibration
When delivered new from the factory, the instrument is calibrated in accordance with the calibration report
provided. A periodical calibration of the instrument every two years is recommended.
As the calibration process is fairly extensive, a full calibration can only be performed at Haefely Hipotronics factory.
It is however possible to perform a standard check and calibration at the local service point. An updated calibration
report will be issued. Please contact support@tettex.com
for more information about calibration services.
16.2.3 Changing Fuses
Before changing the main fuse, remove the mains power cord. Fuses should only be replaced with the same type
and value (Non resettable fuses with 10A / 250VAC / 5x20mm)
