Series 2600A System SourceMeter® Instruments Reference Manual Section 22: Performance Verification
Line power
The Series 2600A requires a line voltage of 100V to 240V and a line frequency of 50Hz or 60Hz.
Verification tests should be performed within this range.
Recommended test equipment
Table 22-1 summarizes recommended verification equipment. You can use alternate equipment as
long as that equipment has specifications equal to or greater than those listed in Table 22-1. Keep
in mind, however, that test equipment uncertainty will add to the uncertainty of each measurement.
Generally, test equipment uncertainty should be at least four times better than corresponding
Series 2600A specifications.
Table 22-1 lists the uncertainties of the recommended test
equipment.
Verification limits
The verification limits stated in this section have been calculated using only the Series 2600A
one-year accuracy specifications, and they do not include test equipment uncertainty. If a
