Chapter 1 Test Overview RIGOL
DM3068 Performance Verification Guide
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 1 year "Allowable Error Range" in Table
2-1 to Table 2-6 in “Chapter 2 Performance Verification Tests”. 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.
NOTE
The multimeter that passes the routine test must be tested again when the test time interval
expires. The multimeter that fails to pass the routine test must be calibrated or repaired before it is
put back into use.
Test Equipments
Table 1-2 lists the equipments recommended for the test. If you do not have such equipments, use
other equipments that fulfill the "Precision Requirements" in the table.
