Parameters for ES413 A/D 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.

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).

Enables or disables the internal hardware anti-aliasing filter.

Enables or disables the digital low-pass filter.

If enabled, a filter with 8th order Butterworth characteristic is applied for optimal signal conditioning. The -3dB 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. Which settings are possible depends on the current acquisition rate.

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

You have the following choices:

• FIR Auto sets the cut-off frequency to a factor of 0.4x of the sampling rate,
• FIR Std sets the cut-off frequency to a factor of approx. 0.2x of the sampling rate,

Enter the lower physical value according to the sensor used.

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

Enter the upper physical value according to the sensor used.

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

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

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

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

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.

Defines the output voltage that supplies connected sensors.
