Directions for use
How to use the collar
The size of the strap of the collar should be just over the dog's neck; make sure that the two output electrodes are against the surface of the dog's skin. If the dog has more hair, please adjust the collar as much as possible so that the electrodes are attached to the surface of the dog's skin.
Description of the function buttons of the remote control:
A: Long vibration: Vibration for about 3 seconds.
B: Short vibration: Vibration for about 0.5 seconds.
C: Long pulse: Impulse voltage for about 3 seconds continuously.
D: Short pulse: single pulse voltage.
The above four functions can represent four movements that require you to train your dog slowly. The button only needs to be pressed for about 0.5 seconds each time, and it is useless to press more.
E: Intensity selection: Adjust the adjustable resistor on the transmitter clockwise with the screwdriver to increase the output pulse intensity of the receiver and vice versa. You should start with a small intensity, observe the dog's reaction, and then gradually increase to an appropriate intensity.

Acidity meter is a common equipment,also known as PH meter, which is mainly used for precise measurement of pH value of liquid medium, and can also measure MV value of ion electrode potential with corresponding ion selective electrode. It is widely used in industry, agriculture, scientific research, environmental protection and other fields. If the electrode an be properly maintained in use, prepare the standard buffer solution as required and operate the electrometer correctly, which can remarkably reduce pH indication error, so as to improve the reliability of chemical experiment and test data.

Taking the acidity meter produced by Kelilong Electron Co.Ltd in Fujian,China as an example. It usually divided into four categories: industrial on-line acidity mete, table type acidity meter, portable acidity meter and pen type acidity meter.As shown in Figure 1.
