where X represents the input module (1-3), on the 2638A

and 1586A.

is used.

Unit Label

The value to apply to the label. For example, the

calculated value can be shown as Watts.

Function

• Take the average reading from one channel.

• Subtract the measurement of one channel from the

measurement of another channel.

• Generate an equation based on measurements.

Alarm Type

Use Normal alarm if the measurement goes above or

below the Alarm 1 or Alarm 2 level. Use Band to alarm if

the signal falls between two levels (2680A and NetDAQ).

Alarm 1 or Alarm 2

Each channel has two alarms. The alarms can be set 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). The Software records all

alarm conditions in a data file.

Digital Output

is detected.

Use Channel as Alarm Trig.

Select if channel reading will be used to trigger an alarm.
