CAUTION:
Avoid writing <=>
continuously, such
as ramping set
points or repetitive
loops, to the
Series 986-989
EEPROM memory.
Continuous writes
may result in
premature control
failure, system
downtime and
damage to
processes and
equipment.
NOTE:
The number of
decimal places
returned by many
of these
commands is
determined by the
DEC1, DEC2, IN1
or IN2 setting.
NOTE:
(RTD setting)
For JIS curve, go
to rtd1 prompt
after selecting In1.
