Description
The ACTIVATION options change based on the SET FUNCTION setting.
Refer to the tables that follow to configure the analog output.
NONE (default)—Sets the analog output to disabled. [analyzer name]—
Sets the analog output to enabled.
Sets the channel represented at the analog output.
Note: Do not select a channel that contains the symbol "~" (e.g., 4-~SAMPLE4).
Channels that contain the symbol "~" are not measured.
Sets the function of the analog output. Refer to the tables that follow for
more information. LINEAR CONTROL (default)—The analog output is
linearly dependent on the measurement value. PID CONTROL—The
analog output operates as a PID (Proportional, Integral, Derivative)
controller. LOGARITHMIC—The analog output is represented
logarithmically within the measurement range. BILINEAR—The analog
output is represented as two linear segments within the measurement
range.
Sets the value of the analog output when an error occurs if the ERROR
HOLD MODE setting is set to TRANSFER OUTPUTS (0 to 25 mA, default:
4 mA). Refer to Set the error hold mode
Sets the amount of time for analog output averaging (0 to 999 seconds,
default: 0 seconds). For example, if the value is set to 30 seconds, the
value of the analog outputs is updated every 30 seconds and the value is
the average of the analog output values during the previous 30 seconds.

analog output.
Description
AUTO—The analog value (mA) is automatically controlled by the algorithm
when the analyzer uses proportional, integral and derivative inputs. MANUAL
—The analog value (mA) is controlled by the user. To change the value
manually, change the % value in MANUAL OUTPUT.
DIRECT—The analog value increases as the measurement value increases.
REVERSE—The analog value increases as the measurement value
decreases.
Sets a value for the difference between the measured value and the setpoint
value.
