Configuration Parameter Settings
Channel The input channel’s name (not editable)
AN1D = analog channel 1, differential input
AN1H = analog channel 1, single-ended high input
AN1L = analog channel 1, single-ended low input
Etc.
Nickname You can specify the Nickname (e.g., Oven 1, Monitor
Room)
Units You can specify the Engineering Unit. When switching
between voltage and thermocouple ranges, this will
automatically switch to the default units for that range.
However, any units label may be typed in here.
On/Off To turn on or turn off the selected input channel
Single/Diff You can select input channel as Single-ended or
Differential input.
Range You can select the voltage input range or thermocouple
type for each input channel. Thermocouples must
always be used with Differential input.
Scale and You can rescale the input signal. This scaled/offset
Offset value will appear in all data displays, and in any saved
data files.
Sampling can be set in terms of “Scan Rate” or “Scan Time”.
Scan Rate = 1/(Scan Time).
For example, if you are acquiring 4 voltage inputs at 250 Hz, you will receive 250
complete scans per second. Meaning each channel will send 250 pieces of data
every second, for a total of (4 x 250) = 1000 pieces of data.
The maximum scan rate is affected by the number of channels turned on.
Selecting thermocouple input also lowers the maximum scan rate.
