7.16. 4mA Adjustment

If the 4-20 mA setting is turned ON (see section 7.2), the following two menus will appear. The
first menu outputs a constant 4 mA while allowing for a small amount of adjustment. The
adjustment can be made using the  and  buttons. This adjustment will allow the operator to
make the AM-TBR agree with a PLC or SCADA system. The adjustment limits are ± 200 counts
or about ± 0.2 mA.

This setting will be slightly different on each instrument as each AM-TBR will be factory set to
4.00mA. Press the ↵ button when adjustments are complete to save this setting and move on to
the 20mA adjustment.

7.17. 20mA Adjustment

This menu operates similar to the previous menu. This menu outputs a constant 20 mA while
allowing for a small amount of adjustment. The adjustment can be made using the  and 
buttons. The adjustment limits are ± 1000 counts or about ± 1 mA.

This setting will be slightly different on each instrument as each AM-TBR will be factory set to
20.00mA.

7.18. Saving Configuration Settings

If extended settings are set to OFF, pressing the

↵

button will save all settings and the AM-TBR

will automatically return to the normal AUTO mode of the instrument.

If extended settings are set to On, after the last menu of the extended settings, pressing the

↵

button will save all settings and the AM-TBR will automatically return to the normal AUTO mode
of the instrument.

The CONFIG menu may be used at any time to reset or change any of the parameters. The
CONFIG menu may be exited at any point in the menu by using the MODE/EXIT key. Any
features that have been modified will be saved.
