Yokogawa 202 Field Mounting Rate Totalizer - Manual (Page 12)

3. PROGRAMMING
The Model 202A is fully programmable, with all parameters being stored in
non-volatile memory.
The Program Mode can be entered in the following way:
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.
The PROGRAM switch is used to step through the program (CAL sequences)
and the and keys on the front panel are used to change and increment the
flashing digits.
The CAL number is displayed on the lower display and the parameter is
displayed on the upper display.
