4 Settings / parameter descriptions

The pyrometer is equipped with a wide range of settings for optimal adaptation to the required

measuring condition and to measure the temperature correctly.

All settings can be read and set only in the pyrometer parameters window of the

software InfraWin. Adjusting the settings at the instrument is not possible (detailed

description of the software see Chapter 5, Software InfraWin).

Selecting the pyrometer parameters window shows the current settings of the

pyrometer. Changing a value can either be done by typing a value in an input box or by

selecting a preset value from the list field.

4.1 Temperature Display

The Digital Display on the back of the pyrometer will show the temperature measurement in

either °C or °F. You can select which temperature scale you wish to use through the InfraWin

software or by using the UPP Data Format commands.

The Measuring Value can also be viewed at any time through the InfraWin Software or by using

the UPP Data Format commands.

4.2 Emissivity ε

Different materials have different emissivities ranging between 0% and 100%. The emissivity is

also dependent upon on the surface condition of the material, the spectral range of the

pyrometer, and the measuring temperature. The emissivity setting of the pyrometer has to be

adjusted accordingly.

Emissivity settings between 5% and 100% can be established through the InfraWin software or

by using the UPP Data Format commands.

Note: Emissivity e can be set from 5% to 100% in steps of 0.1%

4.3 Transmittance t

Transmittance is a parameter that can compensate for signal loss due to external windows etc.

For example, if the emissivity of the material is 0.6 and the transmittance of an additional

window is 0.9, then the product would be 0.54 which is well inside the allowed range.

The product of transmittance and emissivity (t x e) must not be less than 5%.

Note: Transmittance t can be set from 5% to 100% in steps of 0.1%

4.4 Response Time (t

)

The response time t

is the time interval for the analog output of the pyrometer to go from a

low temperature value up to 90% of the temperature step to a high value when measuring an

abrupt increase from said low to said high temperature.

Independently of this, the pyrometer performs a measurement every 1 ms and updates the

analog output. Slower response times can be used to achieve a constant temperature reading

for measuring objects that have rapidly fluctuating temperatures.
