GE K400 user manual Important Note, Calibration of the standard Reference Probe Input

5 CALIBRATION

The DBC series of temperature calibrators must be considered as reference standard: these instruments must be periodically tested and calibrated with a recommended recalibration period of 12 months. The Service Centres of GE provide a global calibration service to National and International standards.

Calibration must be carried out by the suitably qualified calibration technicians. The calibration procedure requires a high-accuracy reference standard (at least 5 times better than the DBC accuracy) with direct traceability to National or International Standard (SIT, UKAS etc.).

Press the # and the menu keys to select the set-up display.
