Managing Your Network Using Fluke DAQ

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.

Open Thermocouple Detection

Provides for notification if an open thermocouple is detected.

Factors (Mx+B)

Used to scale measurements. Mx + B scaling multiplies a measurement by a multiplier (M) and then applies an offset (B). For example, Mx+B scaling of 100x+50 applied to a measured value of 1.15 would result in a reading of 100(1.15)+50=165.

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.

Configuring a Computed Channel

Computed channels provide a means to calculate values based on measurements. For example, if Channel 1 measures dc V and Channel 2 measures dc I, you could use a computed channel to calculate instantaneous power (Channel 1 x Channel 2).

For a computed channel to execute, it must be associated with the scanning of a module. You need to choose a module in the Scan with Module area for this association. The default is module 1.

To configure a computed channel

1.Highlight the Computed Channels icon in the TreeView panel and click the Insert button.
