Do not connect the instrument while the voltage supply source is turned on. Please observe international safety regulations at all times. ► Switch to neutral and verify absence of voltage ►...
Operating instructions 8 Shielding and Grounding 8.1 Equipotential bonding The pyrometer housing is connected to the shielding via the cable connector! Differences in ground potentials might cause an equalising current to flow between devices through a cable shielded at both ends. In this case, be sure to install an additional equipotential bonding line.

Operating instructions 12 Setup 12.1 Two-colour mode When measuring with a two-colour pyrometer, the field of view does not have to be filled entirely by the target object. There might even be particles like dust, steam and smoke in the viewing path that weaken the infrared radiation. LED 3 signals when a measurement is critical.

Operating instructions 13 Aligning and focusing the fiber optic head The fiber optic head has to be aligned on the target. It is important to ensure that the beam path is not obstructed. If the pyrometer has a fiber optic, it could be necessary to focus the measuring head additionally.
Operating instructions 13.1 Safety instructions and precautions Laser Radiation Hazard: Laser radiation can be harmful to eye! The laser pointer operates with a class 2 red light laser. Direct prolonged viewing of a laser beam can injure the retina. There-fore, the following safety precautions must be strictly observed, otherwise the laser may not be operated! •...

Operating instructions OUT2 [mA] 1: Output signal without smoothing function 2: Output signal with smoothing function 14.3 Peak hold function It might often be desirable to determine the peak temperature during a defined time period, for example when the objects to be measured move past the pyrom- eter, resulting in temperature readings which would appear to be cyclical.
Operating instructions OUT2 [mA] 1: Measuring object in front of pyrometer 2: Hold time 3: Measurement time of the second internal peak value memory 4: Measuring readings with peak hold function 5: Measuring readings without peak hold function 14.4 DTD function (Discontinuous Temperature Detection) This function serves to automatically detect the temperature during manufacturing processes with discontinuous or intermittent material flow.

Operating instructions 15.2 Error indications The corresponding LED OUT 1 will flash at Overload output 4 Hz. The display shows "SC1" at 2 Hz. Display ot alternately shows overtempera- ture and measurement reading at = 0.5 Hz. Overtemperature The corresponding LED flashes at 4 Hz when the output is switched off.
Operating instructions • Small objects with medium and high temperatures can also be easily and accurately measured. • When measuring materials with low specific heat, a non-contact method does not induce heat loss which would distort the temperature reading (as is the case with contact temperature probes).
Operating instructions furnace - which applies to all other self-contained targets - always show a reading which is too low. Considerable errors can occur at targets with reflecting, polished or bright surfaces, e.g. molten steel and metal without oxide layer and ceramic materials.

Operating instructions Using a reference emissivity coefficient Apply matte black colour to a part of the surface to be measured. This part has an emissivity of 94 %. At first, measure the temperature of the coloured part. Then make a comparative measurement right next to the coloured part and adjust the emissivity on the pyrometer until it displays the previous measurement reading again.
Operating instructions 18 Maintenance 18.1 Cleaning the pyrometer lens A false temperature reading will be given when the lens is dirty. Therefore, check the lens periodically and clean it, if necessary. Dust can be removed by simply blowing it away or by using a soft brush. A special lens cleaning cloth is ideal, but any soft, clean, lint-free cloth will be suitable.
