Maintenance

Provided it is used in accordance with the users manual, the instrument needs no
special maintenance.

Cleaning

If the instrument is dirty after daily usage, it is advised to clean it by using a humid cloth
and a mild household detergent.
Prior to cleaning, ensure that instrument is switched off and disconnected from
external voltage supply and any other instruments connected (such as UUT,
control instruments, etc.). Never use acid detergents or dissolvants for cleaning.

Calibration Interval

We suggest a calibration interval of one year. If the instrument is used very often or if
it is used under rough conditions we recommend shorter intervals. If the instrument is
used only a few times a year, the calibration interval can be extended to 3 years.
