Temperature Calibration
When selecting the CALIBR button the unit will prompt
the use of a password. The password is 'EVOCAL' and
only will be accepted if the user logged into the system
has Manager priveleges. Because calibration of the unit
can cause serious performance issues, this added level
of security was implemented.

Accurate calibration of the temperature probes is essential for proper operation of
the Distek Evolution Dissolution System. Factory calibration provides accuracy
within ±0.1ºC. Care must be taken when re-calibrating in the field, in order to
realize the full accuracy and range of the temperature sensing system.
All installed temperature probes are factory-calibrated using an NIST-traceable
digital reference thermometer, the Distek TempChek. Distek recommends a 6-
month calibration cycle, during which each probe is checked and adjusted by this
