System Verification Tests These tests apply mainly to system-level, error-corrected
verification and troubleshooting. Tests 27 to 31 are associated with the system verification
procedure, documented in Chapter 2 , “System Verification and Performance Tests.” Tests
32 to 43 facilitate examining the calibration coefficient arrays (error terms) resulting from
a measurement calibration; refer to Chapter 11 , “Error Terms,” for details.

Number
Test Name Description
27 Sys Ver Init Recalls the initialization state for system verification from an 8753ET/ES
verification disk, in preparation for a measurement calibration. It must be done
before service internal tests 28, 29, 30, or 31 are performed.
28 Ver Dev 1 Recalls verification limits from disk for verification device #1 in all applicable
measurements. It performs pass/fail limit testing of the current measurement.
29 Ver Dev 2 Same as 28 above for device #2.
30 Ver Dev 3 Same as 28 above for device #3.
31 Ver Dev 4 Same as 28 above for device #4.
32–43 Cal Coef 1–12 Copies error term data from a measurement calibration array to display
memory. A measurement calibration must be complete and active. The
definition of calibration arrays depends on the current calibration type. After
execution, the memory is automatically displayed. Refer to
Chapter 11 ,
“Error Terms,”
for details.
