6243/44 DC Voltage Current Source/Monitor Operation Manual
4.2 Operation in the DC Source Mode
4-11
(a) Free-run during Operate status
• Measurement is repeated with the specified Period time intervals.
• The measurement time includes both the AC conversion time and data processing time and depends
on the Memory Store mode.
For details, refer to Section 4.9.3, “Integration Time and Measurement Time.”
• Measurement is performed asynchronously and unrelated to changes in source value.
(b) Hold during Operate status
• When trigger is input, measurement waits for the Measure Delay time and then starts.
• Triggers input during measurement are ignored.
(c) Change from Operate status to Standby status in the free run mode, and source value changes including
range changes
• Measurement is not performed during Standby.
• When Operate is specified, the 6243/44 waits for the completion of Operate processing and then
source value is output and after the settling time, the 6243/44 starts measurement.
• In order to minimize noise source, for Operate processing, lower the current value to 1 A or
smaller, set the voltage value to 0 V and then turn ON the Operate relay. (For Standby processing,
turn OFF the Operate relay in the same manner.)
• For a source value change including a range change during operation, the source value waits for the
range change processing time and then changes. Measurement is performed asynchronously and
unrelated to changes in source value.
(d) Change from the Operate status to the Standby status in the hold mode, and source value changes
including range changes
• When a trigger is input during range change processing, the 6243/44 waits for the processing com-
pletion and the Measure Delay time and then the measurement starts.
• Triggers input during the Operate processing and measurement are ignored.
