Operating Manual MPA Miscellaneous Information about this manual The Operating Manual shall enable the user to properly install the pyrometer and those accessories which are necessary. Before starting installation, be sure to read and understand this entire manual, in particular the chapter on safety! The instructions contained in this manual, especially those concerning safety, as well as site-specific regulations governing UV radiation must be complied with at all times! Explanation of symbols...
Operating Manual MPA Copyright This Operating Manual should be treated as confidential. It is solely in- tended for use by persons involved with the instrument. This manual may not be made available to a third party without prior Manufacturer’s consent. Please contact the Manufacturer if the need should arise. ...
Operating Manual MPA User’s responsibility The pyrometer may only be used when it is in perfect working condition. Safety requirements The instrument works with an operating voltage of 24 VDC. The voltage re- quired for operation must be supplied by a separate power supply. This power supply unit must conform to directive DIN IEC 61010.

Operating Manual MPA thus measuring the temperature from the near surface area of the glass. Changes in thickness, different types of glass, or varying moisture con- tents in the atmosphere do not affect the measurement reading owing to the wavelength used. The ARDOMETER MPA 29 was designed with a special band-stop filter and sensor which ignore interfering IR radiation from sources such as daylight or laser beams.
Operating Manual MPA correction for reflected ambient temperature can be controlled using this voltage input. Two serial interfaces (USB and RS485) are available. They enable the user to change all operating parameters such as emissivity setting, tem- perature range, smoothing function or output current range during run- ning operations.

Operating Manual MPA For all pyrometers of the MPA Series the current outputs are short- circuit-proof and share one ground connection via pin 8 of the connector. Each current output can be individually scaled and can be set either at the display or via interface.
Operating Manual MPA Getting Started General installation tips Install the pyrometer in a location where it will not be unnecessarily ex- posed to smoke, ambient heat or water vapour. A false reading (too low) will be displayed when the pyrometer lens is dirty.

Operating Manual MPA Note: Key lock may have been activated at the terminal. When selecting the configuration layer you will be prompted to enter an access code with P000 . To obtain full access to parameter settings, enter P100 otherwise you will only be able to view parameters but not change them.
Operating Manual MPA Output current range For the pyrometer’s two analogue current outputs, select the current loop scale – (0 - 20 or 4 – 20 mA)—which matches that of the downstream signal processing equipment (PLC, display device, controller, etc.). At the pyrometer and at the controller, set the upper and lower limits of the temperature range and the current loop output signal.
Operating Manual MPA Configuration and Setup Signal Conditioning Emissivity and Transmittance Besides the emissivity correction (mentioned in Chapter 6.4), a pyrome- ter must be adjusted for the transmission properties of any supplemen- tary lens and/or protective window screwed onto the pyrometer. Set the pyrometer for the specific transmission factor (a percentage value) which is indicated either in the products’s data sheet or on the lens itself.

Operating Manual MPA Temperature before offset Signal Smoothing Filter When the target object’s temperature is erratic, it makes sense to smooth these temperature fluctuations in order to stabilize the signal. The greater the time constant t (user definable), the lower the effect of these fluctuations on the yielded temperature reading.

Operating Manual MPA Installation of the USB driver The ARDOMETER MPA pyrometer can be addressed via a special driv- er. On systems with Windows 7, 8 or 10 the driver installs a virtual COM interface which allows access to the serial port of the pyrometer. Use the link below to download the driver www.prolific.com.tw (PL2303 Prolific Driverinstaller.zip v1.x.x)
Operating Manual MPA Ports (COM and LPT). You will see a listing of ports and should now be able to see which COM Port the PA USB connection assigned to. The ARDOMETER MPA USB connection will be indicated as a USB-to-Serial Comm Port.

Operating Manual MPA If you make a mistake while making the adjustments, simply enter off- set=0.0 und factor=1.0, or set User Cal. to „off“. Command "A" redefines the pyrometer’s entire measuring range. This new temperature span may be smaller or larger than the range originally programmed by the manufacturer.
Operating Manual MPA body emits at any wavelength the maximum energy possible for the spe- cific temperature. Real bodies do not have this ability. In other words, a black body completely absorbs the radiation without reflection or trans- mission losses. The spectral emissivity coefficient e() of a black body is equal to 1 or 100 %.
Operating Manual MPA Maintenance 16.1 Cleaning the pyrometer lens A false temperature reading will be given when the lens is dirty. There- fore 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.
