5 Good Practice Guidelines
5.1 Looking After Your microK
Your microK is a precision electronic instrument intended for indoor use in a
laboratory or office environment. Nonetheless, it has been designed to be as
robust as practical and will provide many years of service, provided it is properly
maintained.
We recommend that you return your microK to Isothermal Technology or one of
our approved service centres on an annual basis for calibration. Isothermal
Technology has developed a calibration kit for the microK. Contact Isothermal
Technology or one of our appointed distributors if you wish to purchase a kit to
calibrate the microK yourself. The microK should require little maintenance
between calibrations other than routine cleaning.
Under no circumstances should you use sharp or unsuitable objects (such as ball-
point pens) on the touch screen as this will lead to premature failure. It is also a
good idea to ensure that you have clean hands when using the touch screen. You
should ensure that you do not have contaminants such as adhesives or solvents
on you fingers when touching the screen as these will be difficult to remove
without damaging the screen.
The touch screen can be cleaned with a damp (not wet) cloth. Use either a
proprietary screen cleaner (suitable for PC flat panel displays) or water and a
little mild liquid soap on a lint-free cloth to wipe the touch screen. Dry the screen
immediately after cleaning with a lint-free cloth. The rest of the microK should
not require cleaning as often as the display, and can be cleaned in the same way
as the screen. Never use abrasive cleaners (such as ‘cream’ cleaners) on your
microK.
5.2 Making a Good Electrical Measurement
Although the microK is intended for use in temperature metrology, its base
measurements are electrical (resistance or voltage). The limited sensitivity of
