DataTrace Technical Notes
Technical Notes - General
Heat Treatment for Preserving Calibration of Humidity Data Loggers
- Data loggers that measure relative humidity (RH) and temperature are routinely used in Ethylene Oxide (EO) sterilization processes for validation and routine monitoring. Unfortunately, EO is a very reactive compound and when RH sensors are exposed to EO, changes can occur in the RH calibration of the data logger.
Segmented Fo Calculation For Phase Changes
- Companies who are interested in the segmented Fo option can download and install this version of DTW over DTW 4.02, 4.04 or older version of V4.05 (see note below). To create a report utilizing the Profile Phases under Report Options, check the box "Reset Lethality On Phase Change" and the printed reports will calculate the Fo for each new phase based on each period ending.
How To Restore Deleted Profiles
- This document describes how users can restore deleted profiles from DataTrace for Windows.
DataTrace Response To Change
- The speed at which a sensor responds to a change in temperature can be critical to monitoring a process accurately. Every temperature sensor requires a certain time for the temperature reported to react to, and equilibrate with, a change in ambient temperature. Two terms are frequently used to describe this analysis: Thermal Time Constant and Response Time.
Overtemp Damage to Data Loggers
- Temperature parameters are described for the maximum temperature a data logger can experience without causing internal/external damage.
Pre & Post Calibration of Measurement Devices
- The requirement for “Pre” and “Post” calibration of measurement devices used in validation of steam sterilizers is based in the widespread use of thermocouple devices for temperature measurements.
Procedures For Verifying Temperature Calibration
- DataTrace users frequently need a procedure to verify that the Logger calibration is in specification. While the following procedures can verify the calibration, in most cases (MPIII Loggers being the exception) Loggers need to be returned to the factory if they are found to be out of calibration.
Technical Notes - DTW Software
DataTrace for Windows (DTW) software is no longer supported or available for download.
