1-4 Performance Verification
Recommended test equipment
Table 1-1 summarizes recommended v
erification equipment. You can use alternate
equipment if that equipment has specifications at least as good as those listed in Table 1-1. Be
aware, 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 Model 2410 specifications. Table 1-1 lists the uncertainties of the
recommended test equipment including the maximum allowable uncertainty of alternate test
equipment shown in parentheses.
