The dialog box entries include:
CH #
XX-YYY. The first two digits identify the chassis (01-99).
The next digit identifies the module (1-6), and the last two
digits identify the channel (1-20).
Label
Use the label field to identify where the channel is used in
the application.
Unit Label
Used to identify the unit of measurement (°C or °F).
Function
Identifies the type of measurement.
Note
For 2638A and 1586A, on Current ranges, all current
measurements are made with a user-installed shunt
resistor (except Ch X21 and X22 of the 2638A and
1586A which are direct current inputs). To set up a
current channel, the shunt value and Mx+B value
must be entered.
Range
Amplitude range for the measurement. Use auto when
unsure of the range.
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. They 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.
Open Thermocouple detection
Provides for notification if an open thermocouple is
detected.
