Serinus 40 User Manual 2.2
3.5.25 Analog Output Menu
The analog outputs can be set to be either current or
voltage. Only some of the fields below will be displayed
depending on which analog output type is selected. All three
outputs must be the same output type.
Set the upper range limit (in concentration units) to the
desired concentration. This value cannot exceed the Over
Range value. This is the value at which the analog output
should be at its maximum (e.g. 20mA for a current output).
Set to Enabled or Disabled to turn the over-ranging feature on
or off.
This field is only visible when Over-Range is set to Enabled.
Set to the desired over range value. This value cannot be set
below the RANGE value. This is the alternate scale used for
the analog output when over-ranging is active and enabled.
(When 90% of the standard range is reached, this over range
is automatically entered. When 80% of the original range is
reached, it returns to the original range).
Choices are 0V, 0.25V, and 0.5V. This sets the voltage for a
reading of 0. Since the output cannot go negative, this offset
can be used to record negative readings.
Enables the user to calibrate the analog output to be exactly
5V. Increase/decrease the value until the connected
equipment reads 5V.
Enables the user to calibrate the analog output at a low point.
Increase/decrease the value until the connected equipment
reads 0.5V.
Enables the user to set desired current ranges. Choices are 0-
20mA, 2-20mA or 4-20mA.
Enables the user to calibrate the current output at a full scale
point of 20mA. Increase/decrease the value until the
connected equipment reads 20mA.
Enables the user to calibrate the current output at a low point.
Increase/decrease the value until the connected equipment
reads 4mA.
