specifications. You can perform these verification procedures:
• Upon receiving the instrument, make sure it was not damaged during shipment and the
unit meets factory specifications.
• If the instrument’s accuracy is questionable.
• Following calibration.
WARNING The information in this section is intended only for qualified service per-

NOTE If the instrument is still under warranty and its performance is outside specified

course of action. If the unit is not under warranty and it fails to meet specified limits,
refer to the calibration procedures in
Section 2 .
There are two general verification procedures in this section:
