Using SHIFT-CONFIG to conﬁgure stepping and scanning

From the SHIFT-CONFIG key combination, you can select internal or external scanning, the

minimum and maximum channels in the scan list, the time between scans, and the reading count.

1. To conﬁgure stepping or scanning, perform the following:

2. Select the desired measurement function.

3. Press the SHIFT-CONFIG keys to access the step/scan conﬁguration.

4. Select the type of scan (INTernal or EXTernal) by using the ▲ and ▼ keys and pressing

ENTER.

5. Select the ﬁrst channel in the scan list (MINimum CHANnel) by using the , , ▲,

and ▼ keys and pressing ENTER.

6. Select the last channel in the scan list (MAXimum CHANnel) and press ENTER to con-

ﬁrm.

7. The next selection is for timed scans. (This is the Timer control source in the trigger

model.) It sets a user-speciﬁed interval for starting scans. If you choose timed scans, the

Model 2000 prompts for a time interval:

00H:00M:00.000S

Use the , , ▲, and ▼ keys to select a time interval and press ENTER to conﬁrm.

8. Next, you are prompted for a reading count (RDG CNT). This can be less than, equal to,

or greater than the scan list length (up to 1024). It is the number of readings that will be

stored in the buffer. The effects of these choices are further described in the scanning ex-

amples.

9. Press ENTER when done to return to the normal display. Note that scanned readings are

always stored in the buffer, up to the setting for RDG CNT.
