RECOMMENDED CALIBRATION EQUIPMENT
The recommended calibration equipment is listed in Table 5-14. Equivalent
substitutes are acceptable provided that their accuracy is at least four times
better than the accuracy of the parameter specification that is being calibrated. If
less accurate equipment is utilized, measurement uncertainty may be introduced
that would compromise the validity of the calibration.

6.6.3 CALIBRATION SETUP
Calibration must be performed under controlled environmental conditions. The
ambient temperature must be between 20 to 30 °C. Also, the humidity must be
less than 80%. Allow the unit to warm up for 30 minutes at no load prior to
performing the calibration. Refer to Figure 6-23 for a diagram of the test
instrumentation setup.
