based gain control functions are provided through three sub-menus –
‘AUTOSET GAIN’, ‘CHECK/SET GAIN’, and ‘TEST GAIN’. Gain
adjustments should be made to the system when the process is
operating “normally”.
- ‘AUTOSET GAIN’ – performs an automatic test and adjustment of the
pre-amplifier gain setting. It automatically cycles through the pre-
determined gain settings in order to find the optimal gain setting based
on the flow conditions at that time. AUTOSET GAIN should be run
while the process is operating at normal conditions to avoid making an
incorrect gain setting.
- ‘CHECK/SET GAIN’ – enables the user to check the current gain
setting in the pre-amplifier and to manually set it to one of four user
settings 1, 4.65, 21.55, and 98.65.
- ‘TEST GAIN’ – performs a test of the system electronics to determine
if the gain setting is optimal.
