Multimeter UNI-T UT60S how to activate MIN/MAX ?

[Maximus Panin]

How to activate the MIN/MAX function on UNI-T UT60S ? I heard that on some multimeters some functions are not activated and can be activated by contacts. For example, like on Richmeters RM102

Datasheet for controller SD7502

Looking at the block diagram, you need to close legs P12, P14 on the controller.

I tried short-circuiting and short-circuiting for a long time, nothing happens. Is it a matter of firmware?

I think it doesn't have the Min/Max function although the LCD does have those.

You can ask Uni Trend. I am sure it doesn't have such function.
