3.2 Calibration Overview

The LDT-5525 Temperature Controller should be calibrated every 12 months or whenever performance verification
indicates that calibration is necessary.
All calibrations can be done with the case closed. The instrument is calibrated by changing the internally stored
digital calibration constants.

3.2.1 Recommended Equipment

Recommended test equipment for calibrating the LDT-5525 Temperature Controller is listed in Table 6.1. Equipment
other than that shown in the table may be used if the specifications meet or exceed those listed.
