Chapter 1 Test Overview
Test Type
The performance verification test is used to test the measurement performance of the
instrument. You can select from two levels of verification tests (quick test and routine
test).
Quick Test
The quick test is an easy way to inspect the functions and specifications of the
multimeter with higher confidence level. It contains only a few test points and can
evaluate the accuracy drift of the multimeter in normal use; however, it cannot detect
abnormal element failures.
For the quick test, you only need to test the items marked with "Q" in "Chapter 2
Performance Verification Test".
Tip
The quick test is not applicable to instruments with abnormalities in some certain
functions. The multimeter that fails to pass the quick test must be calibrated or
repaired before it is put back into use.
Routine Test
It is recommended that you perform routine test when you obtain the multimeter for
the first time and please compare the routine test results with the values of the
"1-year Test Limit" in Table 2-1 to Table 2-6 in “Chapter 2 Performance
Verification Test”. After that, you can verify the performance of the instrument at
the end of each calibration interval. It is recommended that you calibrate the
instrument at the end of each calibration interval.
Tip
The multimeter that passes the test must be tested again when the test time
interval expires. The multimeter that fails to pass the test must be calibrated or
repaired before it is put back into use.
