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 nineteen 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.
