displayed on LCD screen. All Chinese operation interface, clear graphics,
beautiful, easy to operate.

5.2 Mouse instructions

The function of rotating the mouse is similar to the mouse used on the
computer. It has three operations: "left", "right", "click to select". Through these
three kinds of operations of the mouse, the functions of moving cursor, data
input and operation selection can be realized.
Move cursor: move the cursor by turning the mouse left or right, move the
cursor to the option to be selected, and click the knob to select this item.

Data input

: when the data needs to be modified or input, move the cursor

to the option to modify the data, click the mouse to enter the data modification
operation (the cursor is reduced to the modified position), left or right mouse to
increase or decrease the position, click the mouse to confirm the modification
of the position. Rotate the mouse to enterthe next modification. After the bit by
bit modification, the cursor increases to full cursor, that is, to exit the
modification of data. At this time, you can move the cursor away by rotating the
mouse.
5.3 Instrument instructions

When verifying the SF6 density relay on site, please use the accessories

configured by the instrument to connect the gas circuit and the circuit as shown
in Figure 1, The air inlet pipe is connected with the measuring port of the
instrument and the gas cylinder,and the air outlet pipe is connected with the air
outlet (the non-toxic and harmless compressed gas such as air and nitrogen
can be directly discharged into the air without connecting the air outlet),the
measuring pipe is connected with the measuring port of the instrument and
connected with the SF6 density relay to be tested through the transition joint
(see Appendix 1-14 for the transition joint), and the six core test line is
connected with the instrument Corresponding test points on the wiring cabinet.
