Note: The 4MA can be set higher than the 20 MA level to invert the output current if required.
This may be required to control a dosing pump

The next, prompt will be the turbidity level assigned to the 20 mA output level (20MA) on the
lower row of the LCD display). Select the turbidity level to assign to the 20MA using the and

7.3. Configuring the Error Level

In case of an error in the AM-TBR, the 4-20 mA reading can be used to indicate a problem by
sending the current to either 4.00 mA, 2.00 mA or 0 mA or OFF. In the case of OFF, the 4-20mA
is unaffected by any error condition. The factory default setting is OFF. Select the desired ERLV
by using the  and  buttons then press the  button to accept the desired error response.

7.4. Configuring the RS–485 Port
