Pre-positioning and system prerequisite(s)
This 300K digital thermometer with PC connection is equipped with
special features which enhance some measurements.
By using the 'MAX MIN AVG function for example, it is possible to
ascertain and retain either the largest or smallest measured value
which occurs, or the average value (so-called mean,however not
the arithmetical mean). The 'HOLD' function allows you to retain
rapidly changing measured values (for the measurement records).
By pressing the'TIMER' key, you can start a time-counter (count-
up). By pressing the '°C/°F' key, you can choose between two
measuring units: the 'British Imperial' in degrees fahrenheit and the
'Continental' in degrees celsius. If you finally press the REL key
(with triangular symbol), the current temperature display will be set
to '0.0' and only the difference (delta) will be displayed.
The measuring range stretches from -200°C bis +1,370°C or from -
328°F to +2,498°F. However, the supplied sensor's temperature
range is limited to -50°C bis +200°C. The 300K digital thermometer
is just as universally useful for hobbies as it is for the professional
or educational sectors, etc.
