Resetting
Stop the GETAB command as described in the preceding chapter.
Reset the values for CONV_PAR, FILTER_P and DEADB.
Connect the process input or the jumper in the same way as the reference resistor is connected.
5.5.12 Channel Adjustment on AO Board
All analog output boards are adjusted during manufacture for current output, which means that
units in which the voltage output is used may be readjusted to obtain the full accuracy. The same
applies to spares. The following channel setting can be of interest:
•
Adjustment of the zero point Z
•
Adjustment of gain G
•
Adjustment of the variable gain V
•
Setting of the limits L1, L2.
It is not certain that all circuit boards encountered in this connection have all of these adjustment
possibilities. Before the adjustment, jumper the circuit board for the mode (voltage, current) in
which it is to be used. The connection required is shown in
and
Execute the adjustments in the order in which they are described (Z, G, V, L1, L2).
The output signal is measured on the connection unit after the load is replaced with the
instrument in accordance with
and
