Adding Totalizer to scan list (via front panel)
Toggle the state of the Totalizer channel in the scan list using the SHIFT->CH-OFF key. The TYPE and EDGE controls are set
globally through the SHIFT->CARD menu key.
NOTE
Changing Totalizer settings (“READ” or “RRES”) must be done outside of the scanlist configuration.
Adding to scan list via GPIB
The ROUT:SCAN command is used to add Totalizer to the scan list. When a card that supports Totalizer is in the unit, the To-
talizer channel can only be used as a Totalizer. Whenever it is added to the list it will read the current count value. The TYPE
and EDGE controls are set globally through the SENSe:TOTalize:EDGE and SENSe:TOTalize:TYPE commands.
