When the transmitter is in the Programme Menu
the 4/20mA output current will remain locked at the
value prior to starting programming, and it will
therefore not respond to any input change.
However, calibration of the 4/20mA output via the
'CAL' function, or re-calibration of the 4/20mA
reference via the 'Cond' function will change the
output current.
Once within the Programme Menu the required
parameter can be reached by scrolling through the
functions using the
Up
and
Down
push-buttons as
shown in Figs 5A and 5B. When returning to the
display mode following changes to any
parameters, the transmitter will display four
decimal points for a few seconds while the new
information is stored in permanent memory.
All new BA374NC indicators are supplied
calibrated as requested at the time of ordering. If
calibration is not requested, the transmitter will
have default calibration i.e. 3 wire RTD input; high
resolution display in °C; 4 to 20mA output corre-
sponding to an input and display of 0.0 to 100.0°C.
