HP-306
For example, if the present total is 123.45 and the HIT-2A receives
CL<CR>, the present total is cleared (set to 0.0000), the total in
EEPROM is cleared, and the old total value is 123.45. If the HIT-2A
receives ST<CR>, the HIT-2A echoes with the total 123.45, the old
total value. If the HIT-2A receives pulses to cause the present total to
increment to 0.01 and then receives a ST<CR>, the HIT-2A will echo
0.01, or the present total.
The unit mimics this behavior on the display with the Clear Total Menu
and the Set total menu. The reset total input (magnet or terminal input)
acts the same as the receipt of a CL<CR> from the communications
link.
