4.1 

Battery insertion 

For operating the IGA 15 

plus

 a 9 V 

battery or 9 V rechargeable battery 
is necessary. For insertion of the 
battery remove the locking screw 
and the battery case cover.  
Now the instrument is ready to use. 
 
 
 
 

4.2 

Switch on 

The instrument’s push button has 
two trigger points. 
 
 

First trigger point

:

The instrument is switched on if the button is pushed to the first trigger point. The measurement 
starts after a short self test of approximately 1 second. After releasing the push button the last 
measured value will be displayed for 10 seconds (HOLD function) and the sign “HOLD” is shown 
on the display. After these 10 seconds the instrument is switched off automatically. 
The display indicates “7777” if the measured temperature is below 250°C, it indicates “8888” 
above 1800°C. 

Second trigger point: 

The second trigger point activates the data logger and stores the actual temperature reading. It 
can be adjusted if only the actual temperature value is stored or if a continuous storing should be 
done as long as the push button is hold on the second trigger point (setting of time interval see 

6.10

).  

The data logger can store up to 750 temperature values. Should the pyrometer be switched to 
single value data logging, the data logging is confirmed by a beep and in the display the used 
number of the stored value is indicated for a short time (e.g. for the first stored value STO

#

 01 is 

shown).  

Locking lever:

 The push button can be locked in the second trigger point position with the locking 

lever by pushing the lever upwards. This activates the continuous measuring mode. Pressing the 
trigger once again releases the locking and switches off the continuous measuring mode.  
 
 

4.3 

Sighting 

For exact aiming to the object the pyrometer is equipped with a laser target-
ing light. The laser shows a red flashing circle at the position of the measur-
ing spot on the object. The size of the circle varies depending on the distance 
and has approximately the size of the measuring spot. 
 

If the instrument is in operation, i.e. push button is in first or second trigger point, the laser 
targeting light function can be activated or deactivated by pressing the laser key. If this 
function is activated the laser targeting light is automatically switched on as long as the 
trigger button is pushed.
