Mastech MAS830L (Multimeter) - How to change the battery

A mini video on how to change the battery of the multimeter - Mastech MAS830L model.
I have the 115-in-1 screwdriver set from which I used the PH000 attachment to open the back cover of the multimeter.
The top edge would be hard to open but with a small effort, it would come free from the holding 'tabs'. Once open, remove the dead 9V battery and replace it with a new 9V battery and refit the back cover, tighten the screws and it is done!
