Using SCAN to configure scan parameters
Once the internal or external scan list is enabled, you 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 operation.
1. From normal display, press CONFIG-SCAN. The instrument will display the following:
SCAN OPERATION

2. Select INTERNAL, then press ENTER.
3. Press SCAN. The unit will display the following message:
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 between scans), select NO, then press
ENTER, and go on to step 7. If you wish to use and program the interval between scans,
select YES, then press EN-TER. The instrument will display the following:
INTRVL = 000002.500
6. Using the range and cursor keys, select the desired interval between scan sequences, then
press ENTER.
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?

8. To store scanned data in the buffer, select YES; otherwise choose NO, then press
ENTER.
9. If you elected to store data in memory, the instrument will prompt you as follows:

12. The instrument will then scan using selected scanning parameters. If you elected to store
data in memory, the instrument will display the reading number on the bottom line of the
display as readings are stored.
13. After readings are stored, the following will be displayed:
