Reference ------ ------
To verify the calibration curve only the standardized drying method is permissible
because many other methods used are doubtful and can lead to incorrect
comparison values. If no existing curve fit, then a calibration by the company
Schaller is required.

DETERMINATION OF THE MATERIAL REFERENCE MOISTURE
The principle is a comparison measurement with the dehydration method according
to CEN/TS 14961:2005. Take the measured sample and weigh it. Dry it out in an
oven and weigh it again.

10.0 DEVICE MAINTENANCE INSTRUCTIONS
To provide a long life of your device please does not expose it to strong mechanical
loads or heat e.g. dropping it or direct sunlight exposure. Clean your device using a
dry cloth. Any kind of wet cleaning damages the device.
It is not allowed to load the measuring head incorrect (stress, bending), otherwise it
can be broken. Plug and remove the insertion probe of your BLH straight into the
wood chips.
The instrument is not rainproof. Keep it in dry areas. When the device isn’t used for
a longer period (2 months) or when the batteries are empty, they should be removed
to prevent a leakage of the battery acid.
11.0 EXEMPTION FROM LIABILITY
For miss readings and wrong measurements and of this resulting damage we refuse
any liability. This is a device for quick determination of moisture. The moisture
depends on multiple conditions and multiple materials. Therefore we recommend a
plausibility check of the measuring results. Each device includes a serial number
and the guarantee stamp. If those are broken, no claims for guarantee can be
made. In case of a faulty device, please contact Checkline Europe (www.checkline-
europe.eu) or our dealer.
