The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the reality in the utility model
Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is all belonged to
In the scope of the utility model protection.
Turn the progress of negative terminal pressure difference circuit to a kind of anode pressure difference provided by the utility model with reference to the accompanying drawings and examples
It is described in more detail.
Fig. 1 is the circuit diagram of one embodiment that anode pressure difference of the present utility model turns negative terminal pressure difference circuit, such as Fig. 1 institutes
Show, the anode pressure difference of the embodiment, which turns negative terminal pressure difference circuit, to be included：
Battery input positive terminal, the battery input positive terminal pass through diode D1, diode D2, voltage-regulator diode ZD1 and three
Pole pipe Q1 base stages are connected, and battery input positive terminal is connected by resistance R2, resistance R1, diode D3 with triode Q1 colelctor electrode,
The resistance R2, resistance R1 set the com port of voltage measurement, for measuring the positive side pressure between battery input positive terminal and com port
