7-12 Scanning Model 2700 Multimeter/Switch System User’s Manual
Hold — Reading hold cannot be used with scanning. Do not set up a scan channel to use
hold and do not run a scan with hold enabled.
NOTE When in the scan setup menu, use the edit keys (, , Δ, and ∇) to make
selections and set values. Displayed selections and settings are entered by
pressing the ENTER key.
Saving the configured scan
The configured scan can be saved in a user-saved setup (SAV0, SAV1, SAV2, or SAV3).
For a front panel configured scan, the reading count and timer values are also saved (B04
and later software). However, if the settings for a user setup or power-on setup do not
match the switching module type presently installed, error +520 (Saved setup scancard
mismatch) occurs when the setup is recalled. The scan resets to the factor default settings,
and all channels will open. The saved setup is still retained in memory and can be restored
when the matching switching module is later installed.
The displayed front panel CONFIG menu operates differently from other menus when a
saved front panel scan is recalled. The reading count value in the menu may not reflect the
actual reading count of the scan. For example:
Assume a Model 7700 module configured for a10-channel scan and a reading count of 30.
For this configuration, the instrument will scan through the scan list three times. Now
assume the scan setup is saved in SAV1, and SAV1 is the power-on default. After cycling
power, press SCAN or STEP to run the scan. The scan will run properly. That is, the 10
channels will be scanned three times. However, if you check the reading count in the front
panel CONFIG menu, the reading count will be 10 (instead of 30). This is because the
scan list length “suggests” the reading count value during the setup precess.
NOTE Saving and recalling user-setups is covered in Section 1 (see “Defaults and user
setups” on page 1-20).
