Safety

Intended use
The cable tester Schlüter®-DITRA-HEAT-E-CT is exclusively designed to measure the resistance of the heating cables Schlüter®-DITRA-HEAT-E-HK in floor and wall installations. Any other use is not permitted.

Foreseeable misuse

• Any use exceeding or differing from the intended purpose is considered misuse.
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

It must be consulted in all cases where symbol is marked!

CAUTION! RISK OF MISUSE!
Misuse of the resistance measuring device can lead to hazardous situations.

• Never use the device to measure mains voltage
• Never use a damaged device
• Measure known resistance with the meter to verify that the meter is working properly. If the meter is working abnormally, stop using it immediately.

Batteries

WARNING: Risk of injury in case of improper battery handling!
Improper handling of batteries may cause batteries to explode or harmful fluids to leak from the batteries. This fluid may cause severe skin burns in the event of skin contact, severe poisoning in the event of ingestion, and blindness in the event of eye contact.

• Always use a suitable charging device in case of rechargeable batteries.
• Always insert the battery into the resistance measuring device or the battery charger with proper polarity (+/-). Never attempt to force the batteries into such devices.
• Never attempt to solder or repair batteries or to change, modify, or disassemble them in any way.
• Always keep batteries out of the reach of unauthorized persons (children).

Safe handling of batteries

• Avoid skin contact with spilled battery fluid. In the event of inadvertent skin contact, rinse the skin with plenty of water and soap.
• In case of eye contact with battery fluid, immediately rinse the eye with clear water, including under the eyelid, for at least 15 minutes. Point a gentle stream of water directly at the eye and do not rub. Seek medical assistance immediately.

CAUTION! Risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.

User qualification

CAUTION: Risk of measuring errors if used by inexperienced tradesmen!
Erroneous measurements or device damage may result from unqualified use of the resistance measuring device.

• All activities involving the device should be performed by experienced tradesmen only.

These operating instructions list the following user qualifications for handling the device:

Tradesmen
Tradesmen are skilled in their craft and possess sufficient technical understanding to measure the resistance of the heating cable and the remote sensor with the heating cable and remote sensor tester. Measurements may only be performed by those who can be expected to perform their work reliably and safely. Children and adolescents are not approved for handling this device.

Disposal

ENVIRONMENTAL PROTECTION!
Improper disposal may pose an environmental risk!

Improper disposal can create hazards for the environment.

• Electrical waste, electronic components, and batteries should be disposed of by approved specialist companies.
• In case of doubt, contact the local municipal authorities or specialist disposal companies for information on environmentally sound disposal.

Never dispose of batteries and electronic components in household waste! Batteries and electronic components must be disposed of separately!
