TAU.1 12.1.2, parameter Only use the wavelength-neutral lens protection glass supplied by KELLER. Do not use any commonly available camera lens accessory! Doing so will result in measurement errors. Charging the batteries Connect the battery charging socket of the CellaCast PT to the provided power supply.
Operating Manual PT 18x The charger is only for charging the battery. The rechargeable battery is only charged when the pyrom- eter is switched off. Diopter compensation The pyrometer offers diopter compensa- tion to adjust the sighting device to the user’s vision.
Operating Manual PT 18x Brightness control to protect the eye The CellaCast PT pyromter is equipped with an adjustable polarising filter to con- trol brightness and protect the user’s eye. Aiming at the target Direct the CellaPort to the object to be measured. The target marker in the through-the-lens sighting device indicates the size of the target.
Operating Manual PT 18x Measurement Performing a measurement 1) Traffic light status indicator 2) Measurement area 3) Target object (molten stream) Press the ON-button to switch on the device. The pyrometer starts measuring as soon as you point it at the hot target. The target (metal stream) must remain within the rectangular measurement area as long as the display is blinking.
Operating Manual PT 18x 7 Setting parameters at the pyrometer (basic configura- tion) Use the buttons ▲▼ and the „MODE" button on the rear panel to access and configure parameters. With these buttons you can view and adjust all settings required for operating the pyrometer. Hierarchy of manual configuration: Select Select...
Operating Manual PT 18x In the default configuration, certain parameter settings will be hidden. If required, you can have them shown. Configuration layer C011 Configuration layer C020 How to determine and set material constants In pyrometry, the specific radiation characteristics of the measured object will influence the generated temperature data.

Operating Manual PT 18x Based on our experience, we recommend the following emissivity ratio settings: Grey cast iron: 101 (default) Spheroidal graphite iron: 103 -104 To determine the emissivity ratio of the material surface, you must conduct a comparison measurement using a thermocou- ple probe.
Operating Manual PT 18x Ratio correction emissivity ratio Initialising material constants The CellaCast PT pyrometer lets you store up to 10 material constants. Before you perform a new measurement, simply use the ▲▼ control keys to select your preconfigured material constant for that specific ap- plication.

Operating Manual PT 18x 11.1.1 Threshold limits The start of a measuring cycle is determined automatically and is de- pendent on the following variables: Parameter Function Limit 1 Before beginning the measurement, the tem- LI. 1 perature reading must have been lower than Limit 1 at least once.
Operating Manual PT 18x Parameter Function Sampling time During the sampling time the temperature is T.ACT detected and stored as a temperature value. T.ACT Applies to parameter Sampling time = shortest pour time - time delay - 1 sec. Ideally, sampling should be finished before the end of the pour.
Operating Manual PT 18x Parameter Function Plausibility Upper threshold for permissible deviation, if TSP_) temperature reading > average value Plausibility Lower threshold for permissible deviation, if TSP~ temperature reading is < average value T.OUT If a measuring cycle does not start during the period the saved average will be deleted and reinitialized when the next cycle begins.

You can download the CellaView software here: www.keller.de/its/ PC Interface The CellaPort features a USB port to enable data communication to a PC for remote device configuration and temperature monitoring. Either use the CellaView software or use another standard terminal program.
Operating Manual PT 18x Serial communication starts approximately 2 seconds after the data terminal ready (DTR) control signal is enabled at the inter- face. Activate this signal in the terminal program or device con- figuration. After enabling the interface and selecting parameter settings, the pyrom- eter will automatically transmit data via serial interface (autoprint activat- ed).

Use keys "B", "C" and "D" for direct access to enable adjustments to the Quotient (two-colour) channel. To recalibrate your CellaCast PT, you will require a calibration furnace and a reference standard.
Operating Manual PT 18x Maintenance 16.1 Cleaning the pyrometer lens/protective glass A false temperature reading will be generated when the lens/protective glass is dirty. Therefore check the lens periodically and clean it, if neces- sary. 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.
