Warning!
Incorrect setting of the emissivity factor
can lead to considerable errors of
measured temperature.
Direct the IR temperature transducer towards the surface you want to measure. Keep a distance of approximately 200-500 mm (8- 20 inches)
between the instrument and the object . Reduce the distance between the object and the instrument in accordance with the surface size.
Note: when you get the temperature that differs most to the surroundings, then you probably have got the right direction.
The measurement surface size related to the distance 8:1
Emissivity:
Set the coefficient for surface reflection factor (Emissivity factor) using the table below or check via a contact probe.
Select the item with (UP) and (DOWN) arrow keys.
Sound screen
Listening to a machine sounds enables analysis of gears and low speed bearings (<300 rpm) in an alternative way and can improve analysis
speed and quality.
Viber X3™ makes it possible for the user to listen to the machine while at the same time seeing the vibrations in the
instrument display.
Note that you must choose the
Vibration Screen while the sound is enabled the see the vibration signal.
When a headphone set is connected to the
Viber X3 ™, the Sound Screen can be used to adjust the sound volume (depending on hardware
version there is also a volume control on the headphone cord). Before changing volume, the SOUND function must be ON . Sound output
status is enabled (ON) or disabled (OFF) in the Sound Settings menu.

Warning!
To protect your hearing, y ou should always remove the headphones from your
ears when you move the sensor or re-connect the cable.
Emissivity:
Set the coefficient for surface reflection factor (Emissivity factor) using the table
below or check via a contact probe.
The following temperature settings are possible:
To exit Settings menu, just press again the (MENU) key. All settings will be
stored into the permanent FRAM memory.
To change Emissivity factor, in the Function menu go to Settings then go to
Temp scroll down to Emissivity and use the arrow keys to change the value.
