adverse environmental. the system has been exposed to heavy shipment strain. 

Warranty void if damages caused by disregarding this manual. For consequential damages, NO

 

   

 

 

 

 

 

 

 

 

 

 

liability will be assumed! 

Warranty void if damage to property or persons caused by improper use or disregarding the

 

   

 

 

 

 

 

 

 

 

   

 

 

safety instructions. 

Unauthorized changing or rebuilding the system is prohibited due to safety and permission

 

 

 

 

 

   

 

 

 

 

 

 

reasons (CE). 

Be careful with voltages >25 VAC or >35 VDC! These voltages are already high enough in order to

 

 

 

 

 

   

 

 

 

 

 

 

 

   

   

get a perilous electric shock by touching the wiring. 

The product heats during operation. Make sure there is adequate ventilation. Ventilation slots

 

 

 

 

 

 

 

   

 

 

 

 

must not be covered! 

Only fuses of the specified type and nominal current may be used. The use of patched fuses is

 

   

 

 

 

 

 

 

 

 

 

 

   

 

   

prohibited. 

Prevent using metal bare wires! Risk of short circuit and fire hazard! 

DO NOT use the system before, during or shortly after a thunderstorm (risk of lightning and high

 

 

 

 

 

 

   

 

   

 

   

 

 

 

energy over-voltage). An advanced range of application under certain conditions is allowed with

 

 

 

 

   

 

 

 

   

 

 

therefore designed products only. For details, please refer to the specifications. 

Make sure that your hands, shoes, clothes, the floor, the system or measuring leads, integrated

 

 

 

 

 

 

 

 

 

 

   

 

 

 

circuits and so on, are dry. 

DO NOT use the system in rooms with flammable gases, fumes or dust or in adverse

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

environmental conditions. 

Avoid operation in the immediate vicinity of high magnetic or electromagnetic fields,

 

 

 

 

 

 

 

 

 

 

 

 

transmitting antennas or high-frequency generators, for exact values please refer to the enclosed

 

   

 

 

 

 

 

 

   

 

 

specifications. 

Use measurement leads or measurement accessories aligned with the specification of the

 

 

 

 

 

 

 

 

 

 

 

 

system only. Fire hazard in case of overload! 

Do not switch on the system after transporting it from a cold into a warm room and vice versa.

 

 

 

 

 

 

 

   

   

 

   

 

 

 

 

 

The thereby created condensation may damage your system. Acclimatise the system unpowered

 

 

 

 

 

 

 

 

 

 

 

 

to room temperature. 

Do not disassemble the system! There is a high risk of getting a perilous electric shock.

 

 

 

 

 

     

 

 

 

   

 

 

 

Capacitors still might be charged, even if the system has been removed from the power supply. 

The electrical installations and equipment in industrial facilities must be observed by the security

 

 

 

 

   

 

 

 

 

   

 

 

regulations and insurance institutions. 

The use of the measuring system in schools and other training facilities must be observed by

 

   

 

 

   

 

 

 

 

 

 

 

 

 

skilled personnel. 

The measuring systems are not designed for use in humans and animals. 

Please contact a professional if you have doubts about the method of operation, safety or the

 

   

   

 

 

 

 

 

   

 

   

 

connection of the system. 

Please be careful with the product. Shocks, hits and dropping it from already- lower level may

 

 

 

 

 

 

 

 

 

   

 

 

 

 

 

damage your system. 

Please also consider the detailed technical reference manual as well as the security advice of the

 

 

 

 

 

 

 

   

   

 

 

   

 

connected systems. 

This product has left the factory in safety-related flawless and in proper condition. In order to

 

 

 

 

 

   

 

 

   

 

   

   

maintain this condition and guarantee safety use, the user has to consider the security advice
