Max (mA):
• If the 20ma output has an unacceptable amount of
error. The operator can use the “+” & “-” buttons to
adjust the output
Offset (mA):
• By entering the value of the error from the calibrated
value and the actual value into the offset entry box,
that error will be added/subtracted from the mA val-
ue. The offset is applied to the mA value which should
correct the error. Resolution of error should not be
less than 0.01.
Apply Changes:
• Min (mA) and Max (mA) values are stored to data-
base on press of this button. Offset (mA) value which
is used to correct 4mA or 20mA output is hence not
saved until this button is pressed.
