Quick Start Guide CellaTemp PX 1x, 2x, 3x
1 Best – target larger than the spot size
2 Good – target equal to the spot size
3 Incorrect – target smaller than the spot size
4. Turn on the power supply of the pyrometer.
5. Focus the pyrometer
Pyrometer with through-lens sighting:
Focus the lens until the target and the target marker (distinctly marked circled spot in the
viewfinder) are both clearly visible.
Pyrometer with laser sighting:
Activate the laser spot light by pressing the mode button for 3 s. Observe the laser safety
instruction. Focus the lens until a clear and round laser point is visible.
Pyrometer with camera
When aiming the pyrometer, focus the sensing head until the video images is sharp.
Pyrometer with fiber optic cable and separate optic
For pyrometers with fiber optics, the measuring head must be focused. To activate the laser,
press the MODE button on the rear panel for 2 s. Observe the laser safety instruction. For
focal adjustment, loosen the screw of the measuring head and move the inner tube in order
to obtain a sharp spot on the measuring area.
6. The pyrometer uses the intensity of infrared radiation for non-contact temperature measure-
ments. It is necessary to configure the pyrometer to the respective emissivity coefficient of
the measuring object to obtain the exact measuring results. The emissivity coefficient is to
set as following:
► Press [▲or ▼] until the desired emissivity is shown.
► Release [▲or ▼]
> The current temperature value is displayed and the new emissivity coefficient is stored.
Make sure that the function of the pyrometer is correct. All parameters can be set directly at
the pyrometer. Record the setted parameters.
7. It is advisable to integrate this pyrometer check into the maintenance plan.
The pyrometers of the PX 1x series are only measuring exactly in state of terminal stabili-
zation. The breakperiod is approximately 15 min after starting the supply voltage.
