example, you could set up thermocouple operating parame-
ters for the TMP function and RTD setup parameters as the
ALT function. This arrangement allows you to specify
changes in virtually any measurement parameter from chan-
nel to channel even if the measurement functions are the
same.
SAVE-ALT-FCN: Stores the presently selected function
and all its configured settings as the ALT function.
RESTORE-ALT-FCN: Restores the function that was
saved as the ALT function and all associated settings as if a
normal function change were taking place.

Scan configuration (CONFIG-SCAN)
CONFIG-SCAN allows you to select the internal or external
channel list for scanning.
Pressing CONFIG-SCAN will display the following menu:
SCAN OPERATION
INTERNAL EXTERNAL RATIO DELTA
These choices select the action the instrument will take when
it is triggered.
INTERNAL
This selection enables scanning with the internal Model
2001- TCSCAN scanner card.
EXTERNAL
This menu selection enables scanning with an external scan-
ner card located in a switching mainframe. This selection op-
erates in a manner similar to INTERNAL except that the
internal scanner card is not used.
RATIO/DELTA
RATIO and DELTA should not be used with the Model
2001-TCSCAN. These selections are intended for use with a
different scanner card.

Using SCAN to configure scan parameters
and start scanning
Once the internal or external scan list is enabled, use the
SCAN key to configure scan count, scan interval, and enable
buffer storage. The steps below outline the basic procedure
for using the SCAN key to configure internal scanner opera-
tion.
1. From normal display, press CONFIG-SCAN. The in-
strument will display the following:
SCAN OPERATION
INTERNAL EXTERNAL RATIO DELTA
2. Select INTERNAL, then press ENTER.
3. Press SCAN. The unit will display the following mes-
sage:
SCAN COUNT = 00010
4. Using the range and cursor keys, select the number of
scan sequences, then press ENTER. The instrument will
display the following:
USE SCAN TIMER?
YES NO
5. If you do not wish to use the scan timer (interval be-
tween scans), select NO, then press ENTER, and go on
to step 7. If you wish to use and program the interval be-
tween scans, select YES, then press ENTER. The instru-
ment will display the following:
INTRVL = 000002.500
6. Using the range and cursor keys, select the desired inter-
val (in seconds) between scan sequences, then press EN-
TER.
7. The instrument will then prompt you as to whether or
not you wish to store data in the buffer as follows:
DATA TO MEMORY?
YES NO
8. To store scanned data in the buffer, select YES; other-
wise choose NO, then press ENTER.
