5.5. FETCh

Fetch commands return measurement data that has been previously acquired. FETCh queries do not generate new measurements, but allow additional measurement calculations from the same acquired data.

 

SCPI command

Description

FETCh

:AHOur? {<channel>}

 Returns the delivered energy in amp-hours

WHOur? {<channel>}

 Returns the delivered energy in watt-hours

5.5.1. FETCh:AHOur?

Syntax

FETCh:AHOur? {<channel>}
Description

Not implemented yet

 

Use this command to query delivered energy on the specified channel in amp-hours accumulated after last power-on or SENSe:AHOur:RESet command.

This value is measured independently of channel’s total delivered energy in amp-hours stored in non-volatile memory that can be queried using the SYSTem:CHANnel:INFOrmation:AHOur:TOTal? Command.

 

If channels are coupled (in series or parallel) or in tracking mode, this command will return a sum of delivered energy on both channels.
