2680A/2686A

Getting Started Guide

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.

Note

You cannot select channels in another 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.
