I would say
1: meter put in ohms tests, the dislay fluctuates
2: continuity test, he touch the leads ?
@djdanielb your translation if it is : is hard to read and understand
Have you read the user manual to help you use the meter ? ------------->

If you measure known values of resistances are the displayed values good ?
If you dont have anything connected on the leads sometime an multimeter will read some picked interferences on the leads, they act as antennas.
If you short them together, is the display gets to zero and stay at zero ?
The continuity test : on this meter if the resistance value are less than 20 ohms, you will hear a beep
