Performance Verification
1-2
1.4
Line power
The Model 2001 should be tested while operating from a line
voltage in the range of 90-134V or 180-250V at a frequency
of 50, 60, or 400Hz.
1.5
Recommended test equipment
Table 1-1 lists all test equipment required for verification.
Alternate equipment may be used as long as that equipment
has specifications at least as good as those listed in the table.
See Appendix D for a list of alternate calibration sources.
1.6
Verification limits
The verification limits stated in this section have been calcu-
lated using only Model 2001 one year specifications, and
they do not include test equipment tolerance. If a particular
measurement falls slightly outside the allowed range, recal-
culate new limits based both on Model 2001 specifications
and pertinent calibration equipment specifications.
