Chapter 10: Calibration procedures
10.1 Introduction
Note: GE can provide a calibration service that is traceable to
international standards.
Return of the instrument to the manufacturer (recommended)
or an approved service agent for calibration.
When using an alternative calibration facility, make sure that it
uses these standards.
10.2 Before starting
To do an accurate calibration:
•
use the calibration equipment specified in Table 10-1 .
•
calibrate in a stable temperature environment: 21 ± 1°C (70
± 2°F).
Note: Before starting a calibration procedure, leave the
instrument in the calibration environment for a minimum
period of two hours.
