5.0 COMMON REASONS FOR INCORRECT MEASUREMENTS
• Wrong calibration curve
Double check the correct selection of the calibration curve before measuring. The
calibration curve “reference” must NOT be used.
• Inadequate thickness of the leather pile
A single leather hide must NOT be measured. Pile the leather to ensure a thickness
of at least 10 mm.
• Metal below the material
During the measurement there must NOT be any metal for at least 100 mm under
the measured material.
• Product temperature out of application range
The application range is between 0 °C and +40 °C
• Discrepancy in temperature between device and material
Please ensure that the device and the material under test are being stored at nearly
the same temperature before measuring. A high temperature difference has a
negative effect on the stability of the measurement results.
6.0 LOOKING AFTER THE INSTRUMENT
Do not drop the instrument or expose it to excessive temperatures. Only clean it with a
lint-free, dry cloth. The instrument is not waterproof.
How often you need to check the instrument depends on the use and the required level
of accuracy in your field of operation. For a fee, Messtechnik Schaller GmbH can also
carry out a calibration at their factory. In this case you will also receive a calibration
certificate.
6.1 Exemption from liability
For miss-readings and wrong measurements and of this resulting damages we refuse
any liability. As this rapid measurement procedure is influenced by product-specific and
application-specific conditions, we recommend to carry out a plausibility check on the
measurement results. Each instrument has a serial number and a warranty seal. If this is
broken we cannot provide warranty. If the instrument is defective, contact Messtechnik
Schaller GmbH or your supplier.
