ENTER
tion pressure.
Apply the low range value to the input of transmitter
as specified earlier.
Apply the high range value to the input of transmitter
as specified earlier.
Apply the middle range value. This value is calcu-
lated by STT04 terminal using low and high values.
If configured digitally this adjust selection does not
appear. Adjust transmitter output using up and down
arrow keys.
NOTE: When increasing or decreasing the mA sig-
nal, the increments of change increase with succes-
sive depressions until the maximum level of change
is reached. By changing direction the smallest incre-
ment of change returns. This technique speeds up
the process without affecting fine adjustment.
Adjust the transmitter output using up and down
arrow keys.
