The query form returns 1 if Ratio Self-Calibration is in progress, 0 otherwise.
8.7.3.134 TEST:LIN:REP?
Example response: 0.00000002,0.00000001,0.00000002,0.02,0.003
Reads a report from Ratio Self-Calibration (see Section 9, Calibration, on page 103).
Suffix specifies the test number of which a report is requested:
Linearity self-test type
1 zero check
2 compliment check
3 equal ratio sum, 100% scale
4 equal ratio sum, 90% scale
5 equal ratio sum, 75% scale
6 equal ratio sum, 60% scale
7 equal ratio sum, 50% scale
8 unequal ratio sum
The normal response contains the following:
,,,,
is the mean measurement from the first part of the test.
is the mean measurement from the second part of the test.
is the combined result of the two parts.
is the difference between and the expected value, in units of 1×10-6.
is the standard error of , in units of 1×10-6. The standard errors of and
B> are calculated by dividing their standard deviations by the square root of the sample size, and then the two
values are combined using a root-sum-square calculation.
A report is available only if the Ratio Self-Calibration runs to completion. If no report is available, error
-230,“Data corrupt or stale” is generated in the error queue. If the power is switched off and then on again, the
values , , and will no longer be available and will be missing in the com-
mand response.
8.7.3.135 TEST:LIN:REP:TIME?
Example response: 2009-06-24 14:30:48
Reads the date and time of the most recent Ratio Self-Calibration report (see Section 9, Calibration, on page
103). The date is in the format YYYY-MM-DD. The time is in 24-hour format. If Ratio Self-Calibration has
not yet compled, error -230,“Data corrupt or stale” is generated in the error queue.
8.7.3.136 TEST:LIN[:STAT]?
Example response: 5
Reads the state of the Ratio Self-Calibration (see Section 9, Calibration, on page 103).
A non-zero response indicates calibration is in progress, and the value designates which test number is in prog-
ress. The response is 0 calibration is not running.
8.7.3.137 TEST:LIN:TIME?
Example response: 205
Reads the time remaining of the Ratio Self-Calibration. The time remaining is a number of seconds.
