Safety 3 Safety 3.1 Symbols and Signal Words Used The following symbols and key words are used in the user manual to indicate hazards and instructions. Safety precautions always appear before an action. DANGER Indicates a potentially dangerous situation. Failure to abide may result in light or minor injury and damage. CAUTION Indicates a potentially damaging situation. Failure to abide may result in damage to the product or to anything near the product.
Safety 3.2 General Safety Notes The KLEIBER 740 pyrometer has been built in accordance with the currently valid standards of the technology and the recognized safety regulations and ensures the highest safety level. The fundamental safety and occupational safety requirements of applicable laws, standards, and guidelines have been taken into account in the pyrometer design. The safety of the pyrometer is confirmed by the declaration of conformity and the CE mark.
Technical Description 4 Technical Description 4.1 System Design/Principle of Operation Fig. 1 shows the basic structure of the pyrometer. The basic parts of a pyrometer are the lens, aperture, filter detector, and the signal processing unit. The infrared radiation coming in from the object to be measured is gathered by the lens. The aperture blocks unwanted rays at the edges. The filter permits only the desired spectral range to enter.

Technical Description 4.1.2 Operating and display elements The controls and indicators are located on the rear side of the device. For the meaning of individual elements refer to legend Fig. 5, for operation of the pyrometer see section 7. Fig. 5 4.1.3 Operating and display elements Operating and display element Meaning 1 Push button for pilot light (optional through lens sighting) switch on/ off the pilot light 2 Potentiometer [emissivity] adjustment of emissivity from 0.
Technical Description 3 4 Fig. 6 Connecting plug for 5-pin connecting cable Operating and display element Meaning 3 BNC Output BNC output 0 … 10 V for connection to storage oscilloscope 4 5-pin plug connection Power supply connection and output [0(4) … 20] mA Cooling water connection At ambient temperatures of more than 40°C the pyrometer must be operated with the associated cooling! The two connections for the connection of a cooling circuit are located under the instrument (see Fig. 77).
Technical Description Mounting There is a retaining pin (scope of delivery) through which the pyrometer can be fixed using various brackets. We recommend fixing the pyrometer using the retaining pin and optional available ball and socket mounting support with clamp or thread. This mounting plate ensures secure assembly of the pyrometer as well as optimal adjustment with respect to the object being measured (for order data see page 22).
Transport and Storage 5 Transport and Storage 5.1 Transport of the pyrometer CAUTION Environmental factors, impacts and the formation of water condensation may damage some components! When transporting the pyrometer, take suitable measures to protect all components from environmental factors, impacts and the formation of water condensation! Temporary storage of the pyrometer in the open air is not permitted! Prepare the pyrometer for transport as follows: 1.

Operation of the pyrometer 7 Operation of the pyrometer 7.1 Setting the Vario optic Adjust the necessary measuring distance with the help of the vario optic as follows: 1. If necessary switch on the pilot light by pressing the push button at the rear side. 2. Loosen the ring nut (item 1, Fig. 10) by turning it in a counter-clockwise direction. 3. Move the vario optic (item 2, Fig. 10) forwards and/or backwards, in order to adjust the pyrometer to the required measuring distance.
Operation of the pyrometer 7.2 Adjusting the Parameters Emissivity The emissivity is the relationship between infrared energy radiated from an object and the radiation energy of a perfect emitter (black emitter) at the same temperature and the same spectral range. The emissivity is material-dependent and of a considerable size in order to be able to determine the temperature of an object accurately without contact.
Troubleshooting 8 Troubleshooting DANGER There is a danger of injury and possible equipment damage through incorrect power supply! Let problems relating to an incorrect power supply be eliminated by an electrical specialist! Do not carry out arbitrary work on the electrical components of the pyrometer! Only eliminate such problems yourself when their causes obviously relate to incorrect power supply, under-cooling or contamination of the lens. Do not undertake any interventions into the pyrometer.
Maintenance and Care 9 Maintenance and Care 9.1 General information CAUTION Humidity can lead to the destruction of the electrical and electronic components! Do not use any liquids for cleaning the pyrometer or cleaning the immediate environment of the pyrometer! IMPORTANT The servicing period depends particularly on the operating and environmental conditions and is therefore to be specified by the operator! The pyrometer is largely maintenance-free.
Accessories 10 Accessories Electrical accessory Connecting cable for power supply, length 1.
Taking out of service, Disposal 11 Taking out of service, Disposal 11.1 Taking out of service DANGER Removing electrically live cables risks injury and damage to equipment. Never remove electrically live connecting cables. Before removing a cable, ensure that the power supply has been switched off. Take the pyrometer out of operation as follows: 1. Switch off the power supply to the pyrometer. 2. Remove the cables at the rear side of the pyrometer. 3. If applicable switch off the cooling water supply.
