Warranty
The warranty is for 12 months. Damages caused by incorrect use
by untrained people or start-up by unauthorised people are
excluded from the warranty.
The device complies with the fundamental health and safety
requirements of the applicable EU regulations and was tested at
the factory for perfect functionality multiple times. However, if
faults in the functionality occur and cannot be remedied with the
measures in the chapter Errors and faults, please get in touch
with your dealer or distributor. When making a warranty claim,
supply the device number (see the rear of the device). The invoice
acts as warranty certificate. When manufacturer's instructions or
legal regulations have not been followed, or after unauthorised
changes to the device are made, the manufacturer is not responsible for the resulting damages. Changes to the device or unauthorised replacement of individual parts can drastically impact
the electrical safety of this product and leads to the forfeit of the
warranty. Liability does not extend to damages to people or property caused by the device being used other than as described in
the instructions in this operating manual. Subject to changes to
technical design and model changes as part of constant development and product improvement without prior notice.
No liability is accepted for damages resulting from improper use.
In such cases, entitlements to a warranty are then also forfeited.

Description of the device
The material moisture measuring device T660 is a dielectric
humidity sensor, which can be used for the quick and
non-destructive localization of humidity or moisture distributions.
The device enables the detection of near-surface moisture in
walls or flooring. The measured values will be displayed in real
time.
A minimum, maximum and average function is available for the
direct analysis of the measured data. Besides, the currently
measured value can be recorded via the hold function.
The device further features an alarm function. Once the preset
limit value is exceeded, the device alerts the user through emitting an acoustic signal!
The device is suited for the preliminary check of the building
materials' readiness for covering for subsequent measurements
according to the calcium carbide method (CM measurement). The
moisture indication allows the localization of the most significant
measuring spots to extract material for the CM measurement.
You can connect the device to a computer by using the USB cable
included in the scope of delivery. Then you can extract and analyse your measured results with the optional MultiMeasure Studio
software.
