DATAlogger:STEP
Forces a single measurement only, which is stored in the next datalog location. The microhmmeter
then returns to single trigger mode.
If the log has reached the COUNt value, any further STEP commands will generate an ‘execution
error’. The command will be ignored, and the microhmmeter will remain in the single trigger
mode.
DATAlogger:VALue? <value number|ALL>
Transfers a datalog reading from the memory to the output buffer. A value number of between 1
and POINts will output one reading from that location. If ALL is used, all readings are sent
sequentially to the output buffer from location 1 to POINts. Sending ABORt will cancel the
operation. The output format is:
<record no.>,<“range”>,<resistance>,<“date”>,<“time”>
The “range” will include the letter ‘z’ if the Zero function was used on a measurement, and the
letter ‘T’ if Temperature Compensation was used.
DATAlogger:POINts?
Returns the number of readings actually stored in the datalog memory. The response will be
between 0 and COUNt.
CALCulate:DATA Group
These commands perform statistical calculations on the current contents of the data log. A minimum of
2 readings must be stored otherwise an ‘execution error’ is generated, i.e. bit (4) of the Standard Event
Register is set. This error is also generated if the log contains inconsistent entries, e.g. readings taken
on different ranges.
CALCulate:DATA:MINimum?
Returns the minimum resistance value stored in the data log.
CALCulate: DATA:MAXimum?
Returns the maximum resistance value stored in the data log.
CALCulate: DATA:AVERage?
Returns the average of all resistance values stored in the data log.
CALCulate: DATA:PTPeak?
Returns the peak-to-peak value of the resistance values stored in the data log, i.e. max to min.
CALCulate: DATA:SDEViation?
Returns the standard deviation of the resistance values stored in the data log. This is effectively a
measure of rms noise.
