1-13 Performance Verification Models 2510 and 2510-AT
NOTE The reading limits in Table 1-3 are based on nominal resistance values. Recalculate
new limits based on characterized resistance values and Model 2510 one-year ther-
mistor sensor accuracy specifications (see Appendix A).
7. Repeat steps 1 through 5 for the remaining resistance values in Table 1-3. Be sure to
select the correct resistance range from the THERMISTOR RANGE menu.

culate reading limits using actual characterized resistance values and Model 2510 1-year accuracy specifi-
cations. See “Verification limits” earlier in this section for details.
