First i removed the 2 bottom screws

Then i opened the bottom cover

Now we are going to see the inside of this multimeter

At the bottom we have an 9v battery (i made an tutorial on how to replace it) Link: Varo Digital Multimeter

On the left of the 9v battery we have the connectors for the test probes wich is important because otherwise the multimeter cannot measure voltage, amps, etc.

Above the probe connectors we have the 2 fuses both fuses are 0.5A/250V (i do not have a guide to replace these yet)

And above the 2 fuses we have the brains of this multimeter unfortunately i do not know what chip it is.

Last but not least we have the multi digit display.
