Scanning
Adding Channels to a Scan List
Before you can initiate a scan, you must configure the channels to be
scanned and set up a
scan list (these two operations occur
simultaneously from the front panel). The instrument automatically
scans the configured channels in ascending order from slot 100 through
slot 300.
To Build a Scan List From the Front Panel:
To add the active channel to the scan list, press . Select the
function, range, resolution, and other measurement parameters for this
channel. You can also press
to sequentially step through the scan
list and take a measurement on each channel (readings are not stored in
memory). This is an easy way to verify your wiring connections and
channel configuration (also valid during a scan).
• When you reconfigure a channel and add it to the scan list, it is
important to note that the previous configuration on that channel is
lost. For example, assume that a channel is configured for DC voltage
measurements. When you reconfigure that channel for thermocouple
measurements, the previous range, resolution, and channel delay are
set to their Factory Reset (
*RST
command) state.
• To remove the active channel from the scan list, press and select
CHANNEL OFF . If you decide to add that channel back to the scan list
with the same function, the original channel configuration (including
scaling and alarm values) is still present.
• To initiate a scan and store all readings in memory, press (the
SCAN
annunciator will turn on). Each time you initiate a new scan,
the instrument clears all previously stored readings.
• To stop a scan, press and hold .
