Alarm 1 or Alarm 2
Each channel has two alarms. You can set the alarms to Off, Low, or High. An
alarm condition occurs when a measurement falls below a low alarm value
(Low) or rises above a high alarm value (High). Fluke DAQ records all alarm
conditions in a data file.
Digital Output
Used to output a digital signal or close a relay if an alarm is detected.
Use Channel as Alarm Trigger
Select if channel reading will be used to trigger an alarm.
Trigger Scan With Module
Calculate the computed channel any time a module is scanned.
Channel A or Channel B
Select from the configured channels in the device.
Equation
See Appendix E for detailed information on computed channel equations.
Average Channels
Select which channels you want to average.
Factors (Mx + B)
Used to enter a linear equation in two ways. You can either enter the slope (M)
and offset (B) or enter input range. Scale range, slope, and offset are entered
automatically when you press the Calculate button. "X" will be replaced with
the computed channel number.
Input or Scaled Range
Use the M and B values to calculate the Input and Scaled range or you can
enter the Input and Scaled range and Fluke DAQ will calculate the M and B
values for you.
