4. PROGRAMMING
The Model 202D is fully programmable with all parameters being stored in
non-volatile memory.
The Program Mode can be entered in one of two ways:
1. By removing the lower cover strip (ie. the dark grey strip along the
bottom of the enclosure) and replacing it the wrong side up. This brings
a small magnet on the inside of the cover strip in contact with a reed
switch inside the instrument.
2. By removing the front section of the enclosure which contains the main
processor board and batteries.
The PROGRAM switch is used to step through the program (CAL sequences)
and the ∆ (ACCUM TOTAL) and > (RESET) keys on the front panel are used to
change and increment the flashing digits. Note that only flashing digits can
be changed.
Up to eighteen CAL steps are accessible depending on which options are
installed.
The CAL number is displayed on the lower display and the parameter is
displayed above it.
Parameters in Program Mode that consist of the two parts, whole numbers
and digits after the decimal point, are restricted to having a maximum of 6
significant digits. Therefore the number of significant digits entered in the
whole numbers determines the number of digits that are able to be entered
in the digits after the decimal point.
For Example
000001 in the whole numbers makes 00000 available after the decimal place.
000100 in the whole numbers makes 000 available after the decimal place.
010000 in the whole numbers makes 0 available after the decimal place.
