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 .
