Front Panel Operation: View > READINGS

Remote Interface Operation: The following command retrieves stored readings from memory (the readings are not erased).

FETCh?

Use the following commands to query the statistics on the readings stored in memory for a specific channel or from the internal DMM. These commands do not remove the data from memory.

CALC:AVER:MIN? (@3005)	Minimum reading on channel
CALC:AVER:MIN:TIME? (@3005)	Time minimum was logged
CALC:AVER:MAX? (@3005)	Maximum reading on channel
CALC:AVER:MAX:TIME? (@3005)	Time maximum was logged
CALC:AVER:AVER? (@3005)	Average of all readings on channel
CALC:AVER:COUNT? (@3005)	Number of readings taken on channel
CALC:AVER:PTPEAK? (@3005)	Peak- to- peak (maximum–minimum)

The following command retrieves the last reading taken on channel 1 on the module in slot 3 during a scan.

DATA:LAST? (@3001)

The following command clears the contents of statistics memory for the selected channel.

CALC:AVER:CLEAR (@3001)

Use the following command to determine the total number of readings stored in memory (all channels) from the most recent scan.

DATA:POINTS?

The following command reads and clears the specified number of readings from memory. This allows you to continue a scan without losing data stored in memory (if memory becomes full, new readings will overwrite the first readings stored). The specified number of readings are cleared from memory, starting with the oldest reading.
