4.4.2 Analog Tab
The following are the parameters on the Analog tab on the Sensor Settings pane. This tab is available for analog models.
Analog Span
Define the outer limits of the analog range. This can be used to create a positive or negative slope.
Analog output options:
Current: 4 mA to 20 mA
Voltage: 0 V to 10 V or 0.5 V to 4.5 V

Output
Loss–of–Signal: Sets the Analog Output value used by the sensor during a loss of signal. When a signal is
restored, measurement resumes.
Hold Last Value—The Analog Output holds the last value indefinitely during a loss of signal.
3.5 mA (0 V)—The Analog Output switches to this value 2 seconds after a loss of signal. For Voltage models,
this is 0 V. (Default)
20.5 mA (10.5 V/5 V)—The Analog Output switches to this value 2 seconds after a loss of signal. For Voltage
models, this is 10.5 V.
Averaging: Use this menu to set the number of measurements that are averaged together for the analog output.
Increasing the averaging improves repeatability but increases the total response speed. The default is 1. The filter
can be set to 1, 2, 4, 8, 16, 32, 64, or 128. The total response time is show under Response Time.
Response Time
Calculates the total response time, taking into account the general response speed and averaging.

4.4.3 Discrete 1 Tab
The following are the parameters on the Discrete 1 tab on the
Sensor Settings pane.
Output Mode
Select Switch Point or Window.
Switch Point: The distance at which the switch point threshold is placed.
Window: Define two set points to create window limits.
