Calibration
Note: GE can provide a calibration service that is traceable
to international standards.
We recommend that you return the instrument to the
manufacturer or an approved service agent for
calibration.
If you use an alternative calibration facility, make sure that
it uses these standards.
Calibration - Before you start
To do an accurate calibration, you must have:
• the
calibration equipment specified in Table 8.
• a stable temperature environment: 70 ± 2°F (21 ± 1°C)
Table 8: Calibration equipment
Before you start the calibration, make sure that the time
and date on the instrument are correct (Table 1).
Selection sequence:
➤ Task selection menu ➤ Set Up (Table 1) ➤ Calibration ➤
Table 9: Calibration options
When you select a channel/function, the display shows the
applicable instructions to complete the calibration.
When the calibration is complete, select Calibration Due
and set the new calibration date for the instrument.
