Calibration
A calibration check can be done by any user/distributor by comparing the values measured by
MetPak with a reference value or in an environmental chamber. Users should understand that
these checks are not the same as the calibration checks or calibration done at Gill but they can
provide users with some degree of confidence to the validity of their measurements. If a
user/distributor notices a significant difference between the MetPak and their test
environment/reference they should contact Gill to discuss this and see if a calibration is required.
See individual parts above for any recommended calibration periods.
8.2.9.
Returning the MetPak
If the unit has to be returned, it should be carefully packed in the original packaging and returned
to your authorised Gill distributor, with a full description of the fault condition. An RMA number
should be obtained from Gill Instruments first if returning directly to Gill Instruments.
