Model 2750 Multimeter/Switch System User’s Manual Scanning 7-13
Scan reset
From the scan configuration menu, you can reset the scan configuration to the default
setup for a simple scan.
For the Model 7700 switching module, channels 21 and 22 are turned off (not used), and
channels 1 through 20 are configured as follows:
Function - DCV
Range - Auto
Rate - Slow
All other multimeter features and functions are disabled.
When the scan is run by pressing STEP or SCAN, channels 1 through 20 will be scanned
and the 20 DCV readings will be stored in the buffer.
Perform the following steps to reset the scan configuration:
1. Press SHIFT and then CONFIG to enter the scan configuration menu.
2. Press the
Δ
or
∇
key to display INT: RESET and press ENTER.
After briefly displaying “LIST RESET,” the instrument returns to the normal measure-
ment state.
Simple scan
For a simple scan, you specify a starting channel (MIN CHAN) and an ending channel
(MAX CHAN) for the scan. These settings determine the number of channels in the scan.
For example, if you set MIN CHAN to 101 and MAX CHAN to 110, there will be 10
channels in the scan list.
The starting channel number must be lower than the ending channel number. If you enter
an invalid value, the message “TOO SMALL” or “TOO LARGE” will be displayed
briefly. The displayed channel number will default to the lowest available channel (i.e.,
101) or the highest available channel (i.e., 220).
Perform the following steps to configure a simple scan:
1. While in the normal measurement mode, set up the instrument for your test. This
setup will be used for all selected channels in the scan.
2. Press SHIFT and then CONFIG to access the scan setup menu.
3. Press the
Δ
or
∇
key to display “INT: SIMPLE” and press ENTER.
4. Set the minimum channel (MIN CHAN) for the scan and press ENTER.
5. Set the maximum channel (MAX CHAN) for the scan and press ENTER.
6. Enable (Yes) or disable (No) the timer and press ENTER.
