Q& A:

I have about this product. Is it possible to disable the automatic sleep function in any way at all?

PH-870 doesn't have the disable APO function.

But there are two methods to disable APO temporarily.

1. To start max/min function, the APO will be disabled.

2. The meter keeps connecting with PC.
