Setting Up and Using vLog—Overview

Ensuring Loggers are Calibrated
Vaisala Veriteq loggers are calibrated at Vaisala Canada Inc
and should be calibrated on a suitable frequency as
determined by the accuracy requirements of the application
in which the product is used.
If you use vLog VL, the Calibration frequency should be
specified when the loggers are purchased, and the next
calibration date pre-set in the logger. Vaisala Canada Inc
recommends a 90-day interval for the most critical
applications, while a one-year interval may be adequate for
less demanding situations.
To calibrate your loggers, contact Vaisala Canada Inc for
pricing, lead times, and delivery arrangements.
Note: Treat the calibration process very carefully. The
consequences of poor calibration can be very
expensive. Vaisala Veriteq loggers are high-
accuracy instruments. In order to maintain the
specified accuracy, it is essential to have trained
calibration personnel, strict calibration proce-
dures and proper test and calibration facilities. If
you have questions about the calibration pro-
cess, contact [email protected].
Validating Loggers (vLog VL)
For companies that are required to validate the vLog system
(including VL-Series Validatable Data Loggers and vLog VL
software) prior to use, Vaisala Canada Inc provides a
comprehensive protocol document.
Each package includes installation qualification (IQ) and
operational qualification (OQ) procedures, and forms. The
information and forms are provided as hard copies in a 3-ring
binder and in electronic form (Microsoft Word documents) on
a CD-ROM. The electronic files provide an easy way for you
to customize the forms for the application.
