The PosiTest OTL Barrier Box is constructed of stainless steel
and contains NO silicone components. No maintenance should be
required to maintain optimum performance. As a result of use, the
fiberglass insulation cloth may become discolored. This is normal
and will not affect performance.
The PosiTest OTL Holder XT (included with PosiTest OTL XT
Kit) contains a phase change material. This material has a melting
temperature of 58°C (136°F). When exposed to higher
temperatures, the heatsink material will absorb thermal energy
until fully melted. The phase change material is specifically
engineered to melt and become a liquid during normal use.
IMPORTANT:
Do not reuse the Heatsink until the phase
change material has returned to a solid state. To accelerate
solidifying of the phase change material, the Heatsink can be
placed in a refrigerator or freezer.
Care must be exercised to not puncture the Heatsink. If the
Heatsink enclosure is damaged, DO NOT USE. Replacement
Holders are available.
Calibration
The PosiTest OTL and each thermocouple sensor are shipped with
a Certificate of Calibration showing traceability to a national
standard. For organizations with re-certification requirements, the
PosiTest OTL may be returned at regular intervals for calibration.
DeFelsko recommends that customers establish their instrument
calibration intervals based upon their own experience and work
environment. Based on our product knowledge, data, and customer
feedback; a one-year calibration interval from the date the
instrument is put into service is a typical starting point.
