EPROM and memory
The instrument program is contained in an EPROM on the lower circuit board. Version on the
setup menu shows instrument type plus EPROM version and date.
To exchange the EPROM (in case of an update), the instrument casing is opened by removing two
screws at the input connector end, rear side, and lifting off the lower part of the casing. The
connector (A) is pulled off and the upper circuit board unscrewed (B). The EPROM (C) is carefully
levered out of its socket with a small, flat screwdriver and carefully replaced with the new version.
The memory capacity is 128 kbyte. How this translates into the number of measuring points and
measuring results that can be stored in a data logger depends mainly on two factors:
• length of measuring point number and name
• number and kind of measuring techniques used per point.
The upper limit is 999 measuring points, because the running number of the point in the round is 3
digits long. Using 6 measuring techniques per point, the typical number is 500 measuring points. At
a measuring time of one minute per point, that is more than enough for a working day. In practice,
measuring rounds are normally much smaller.
