OUTPUTS MENU (ANALOGUE OUTPUT)

The instrument is equipped with two galvanically-separated and independent current analogue
outputs. The first output is associated with the primary measurement and is therefore proportional
to the measured Turbidity / suspended solids value. The second, on the other hand, can be
programmed as either Temperature or Cond.
G1) Measurement
This programming step allows for 4 functions to be configured:
OUTPUT RANGE:
Can be set to either 0-20mA or 4-20mA. By default this range is set to 0-20mA.
LOWER LIMIT:
A Turbidity / suspended solids value of 0 or 4mA can be attributed to the current output. By
default, this value is set to 0NTU.
UPPER LIMIT:
A Turbidity / suspended solids value of 20mA can be attributed to the current output. By default,
this value is set to 20.0NTU.
The adjustment of the Upper and Lower Limit functions allows for the scale of the analogue
output to be increased or decreased. They also allow for the output to be inverted to 20-0mA or
20-4mA
NAMUR OUTPUT:
This function is only enabled if the Output Range is set to 4-20mA. If this function is enabled, the
value of the current output will be brought to 2.4mA according to the NAMUR standard in the
event of an alarm. By default, this function is disabled.
