Parameters for ES415 A/D Measurement Module

The following list shows the module parameters for the ES415 measurement module:

Enter a number to change the channel sequence.

For example, if you enter 1 for channel 3, this channel comes first. The original channel 1 is then moved to position 3.

Use this checkbox to enable or disable this signal for further configuration steps.

Disabled signals will not be available in the Experiment Environment.

You can also use the context menu commands Enable All Channels and Disable All Channels to enable or disable all channels at once that are displayed on the selected tab.

If a TEDS cable is connected and it contains incorrect values (e.g. sensor supply = 20 V), the channel is automatically disabled and not available for configuration.

Shows the name of the channel.

Enter the unit according to the sensor connected and the signal to be measured.

The selected unit appears in the corresponding measure windows.

Defines the default acquisition rate necessary for your measurement task.

The acquisition rate can be selected separately for each channel of a device. It is used as default rate within the measuring environment (e.g. INCA Experiment Environment), but you can overwrite it (e.g. in INCA's Configure Variables dialog).

Note

A large number of channels with high acquisition rate can push your system to its performance limits.

If the device has only one acquisition rate, this value cannot be edited.

Enables or disables the internal hardware anti-aliasing filter.

Note

For this module, the AA Filter parameter is always set to On..

Enables or disables the digital low-pass filter.

If enabled, a filter with 2nd order CIC (moving average) characteristic is applied for optimal signal conditioning. The cut-off frequency is set in the Filter Frequency column.

When the digital filter is turned off, the field turns red to indicate that aliasing effects might occur, i.e. that signals can be distorted. In the Filter Frequency column the string --- is displayed to indicate that no filter frequency is selected.

Defines the -3 dB cutoff frequency of the digital filter for the signal conditioning of the channel.

This setting is enabled only if the parameter Digital Filter is set to On.

You have the following choice:

  • CIC auto sets the averaging time to a factor of 1x sampling rate.

Enter the lower physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

Enter the upper physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

Enter the value of the lower sensor signal according to the lower physical value.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

Enter the value of the upper sensor signal according to the upper physical value.

Note

You can only enter a value if the formula used has the type "Identity" (Sensor = phys) or "Linear", i.e. the sensor connected to this channel is subject to linear calibration. However, if you use a special conversion formula, this field is empty.

When you click into this field, an editor opens where you can create special conversion formulae.

Note

If you use a special conversion formula, the fields of the Phys bottom, Phys top, Sensor bottom and Sensor top parameters are empty.
If you modify the values in the fields Phys bottom, Phys top, Sensor bottom or Sensor to the formula is automatically adapted.

Enter the lower limit of the expected physical measurement range.

This value is used together with the values of the Phys bottom, Sensor bottom and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Enter the upper limit of the expected physical measurement range.

This value is used together with the values of the Phys top, Sensor top and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Shows the lower physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys bottom, Sensor bottom and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.

Shows the upper physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys top, Sensor top and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.

Enter any comment for that signal.

Enter a number to change the channel sequence.

For example, if you enter 1 for channel 3, this channel comes first. The original channel 1 is then moved to position 3.

Shows the name of the channel.

Defines how the output voltages can be selected:

  • predefined

    You can choose between different preset supply voltages provided to the sensor connected to this channel.

  • user defined

    The output voltages you define are used. If you enter output voltages which are below or above the minimum or maximum value respectively, the software automatically replaces your entry by the closest possible value.

Defines the output voltage that supplies connected sensors.
