2.7 Calibration, software validation
WHALETEQ SEEG 100E has undergone a detailed system validation including software. A
report for this can be provided on request.
Prior to shipping, each unit is tested for component values and output voltages, using a
calibrated precision multi-meter. As WhaleTeq cannot provide ISO 17025 accredited
calibration, laboratories which are required to follow ISO 17025 should perform calibration
either periodically or on a before use basis, following normal procedures and practice. The
extent of calibration may be limited depending on the needs of the laboratory.
As the calibration procedure is complicated, a software assisted calibration mode is
provided. The software sets up the SEEG as required for the particular tests, and instructs
the user on what measurement to make (e.g. measure resistance between ch1 and ch2).
The user then enters the results into the form provided, and the software checks if the
results are within allowable limits. When complete, the results of calibration are
automatically copied to the notepad and stored in a text file at:
C:\WhaleTeq\SEEG_Cal_yyyymmdd.txt
Where
“yyyymmdd” is the date based on the PC’s system. If a fixed width font such as
“Courier New” is used, the data appears aligned.
The following manual procedure is retained here for reference and explanation.
