User Manual User Manual TrackSense LyoPro – MAN 7
• A weak battery will typically show less than 3.1V when inserted
into the activator, at the end of its lifespan, it can also show 3.5-
3.7V. In both cases, the initial voltage will begin to drop after a few
minutes in the activator.
Note: Leaving the battery in the activator for more than 1 hour will cause
the battery to drain at a rate of 2.0 mAh an hour.
8. Calibration
8.1. Ellab Factory Calibration
It is recommended that TrackSense LyoPro data loggers are returned to Ellab at
least once a year for factory calibration. Ellab performs the factory calibration,
which adjusts and notes a new calibration date in the data logger. A certificate
is generated, and the as found / as left data are included by default.
All calibrations performed by Ellab are NIST and NPL traceable. If received, the
ETS firmware will also be updated. The software will (by default) automatically
warn users 12 months after the last calibration date, which should be
considered a recommendation for temperature sensors built on Ellab’s
experience.
The factory calibration date can only be changed by Ellab, this means that the
factory calibration cannot be affected by any of the possible user calibration
procedures performed in the ValSuite software. Please note that the
calibration certificates express an instant view of the performance, this is why
the Ellab factory calibration certificates does not include a recalibration due
date.
Note: When shipping equipment back to Ellab for calibration/inspection,
please ensure that the equipment is packaged well. Ellab is not responsible for
any equipment damaged in shipments sent from customers.
