2. For your safety
The device complies with the following European directives:
• Restriction of Hazardous Substances in Electrical and Electronic Equipment
(RoHS)
• Electromagnetic compatibility (EMC)
The device corresponds to state-of-the-art technology. However, it is still associated
with a number of residual hazards.
These hazards can be avoided through strict observance of our safety information.
2.1 Proper use
• Easy to use device with external sensors for quickly measuring the moisture con-
tent of floor screed, concrete and other building materials.
• The device must only be used for taking measurements on the products defined
in the following sections of this manual (see "7. Product types").
2.2 Improper use
• The device must not be used in ATEX.
• The device is not waterproof and must be protected from water and fine dust.
2.3 User qualifications
The device must only be operated by people who can be expected to reliably take the
measurements. The device must not be operated by people whose reaction times may
be slowed due to, e.g. the use of drugs, alcohol or medication.
All persons using this device must have read, understood and follow the instructions
provided in the operating manual.
2.4 General safety information
The following safety information has to be observed at all times to avoid damage to
objects and injury to people:
• Remove the batteries if the device is not used for a prolonged period of time
(4 weeks).
• Keep the measuring tips of the hand electrode or ram electrode away from your
body throughout all activities.

humimeter GF2 Operating Manual
Page 20
• Keep the measuring tip of the hand electrode or ram electrode away from other
people throughout all activities.
• In case of damages or loose parts on the device, remove the batteries and con-
tact Schaller Messtechnik GmbH or your dealer.
All of the device’s technical features have been inspected and tested before delivery.
