For example, if the prese nt total is 123.45 and the HIT2a receives
CL<CR>, the present total is cleared (set to 0.0000), the total in
EEPROM is cleared , and the old total value is 1 23.45. If th e
HIT2a receives ST<CR>, the HIT2a echoes with the total 123.45,
the old total value. If t he HIT2a receives pulses to c ause the
present total to increment to 0.01 and then receives a ST<CR>, the
HIT2a will echo 0.01, or the present total.
The unit mimics this behavior on the display with the Clear Total
Menu and the Set to tal menu. The reset total input (magnet or
terminal input) acts the sam e as the receipt of a CL<CR> from the
communications link.
