CAUTION:
Avoid writing <=>
continuously, such
as ramping set
points or repetitive
loops, to the
Series 996-999
EEPROM memory.
Continuous writes
may result in
premature control
failure, system
downtime and
damage to pro-
cesses and
equipment.

NOTE:
The number of
decimal places
returned by many
of these com-
mands is deter-
mined by the
DEC1, DEC2, IN1
or IN2 setting.
