3.2.3 Temperature difference submode (∆T)
Press the key to enter the temperature difference submode,the interface[ FIG.3 ]dis-
MODE
plays the measured pressure,temperature and temperature difference values at the high
and low pressure sides.
3.3 Vacuum Measurement Mode（VAC）
1.Connect the refrigerant hose on the high-pressure side to the tested system and open the
high-pressure valve.
The high-pressure side channel is the vacuum test of the system.
2.Press the +

interface.
3.The product connects the vacuum pump and the tested system.
4.Start the vacuum pump to extract the pressure in the system.
！
When the pressure in the system is lower than atmospheric pressure (i.e. the pressure display is less than
0)the system vacuum degree is displayed,otherwise, - - - - is displayed.
5.The interface [ FIG.4] displays the current pressure value of the system, the vacuum degree
of the system and the timing of entering the interface .
