Chapter 4 Features and Functions

Totalizer Operations

∙The maximum count is 67,108,863 (226-1). The count rolls over to “0” after reaching the maximum allowed value.

∙You can configure the totalizer to reset its count after it is read without losing any counts (TOTalize:TYPE RRESet command). Then, if the totalizer is included in a scan list, the count will be reset

on every scan sweep. The count is also reset whenever it is read

directly by pressing from the front panel or when sending the

SENSe:TOTalize:DATA? command.

∙You can configure the instrument to generate an alarm when a specific count is reached on a totalizer channel. These channels do not have to be part of the scan list to generate an alarm. Alarms are evaluated continuously as soon as you enable them. For more information, see “Using Alarms With the Multifunction Module”

on page 130.

∙You can monitor a totalizer channel even if the channel is not part of the scan list (the internal DMM is not required either). The count on a totalizer channel is not reset when it is being monitored (the Monitor ignores the totalizer reset mode).

∙A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet command), and Card Reset (SYSTem:CPON command) reset the count to “0”.

∙Front-Panel Operation: After selecting the totalizer, press to read the count. If you have selected the READ + RESET mode, the count is reset each time it is read. The count is displayed until you press another key, turn the knob, or until the display times out.
