(I) Daily maintenance of the instrument

1Is the power cable interface firm and is the wiring correct?
2Is the argon balance sufficient? Is the traffic normal?
3Is the entrance slit distance correct?
4Is the amount of water in the argon booster sufficient? Is the water clean?
5 Is the temperature displayed by the thermostat at 40 ° C?
6 Is the analysis room kept at 23 ± 5 ℃?
7 Is the vacuum pump oil level normal?
8 There is no dust on the surface of the instrument.

(Two) maintenance items at intervals

Electrode regeneration
• The instrument is excited (discharged) 200 times, and the electrode is ground and regenerated;
• Turn off the light source switch (SOURCE) on the instrument panel;
• Open the door of the light-emitting chamber, clamp the electrode rod with a special tool—electrode gauge, loosen the lock nut on the electrode holder, and remove the electrode rod (Note: After loosening the nut, do not loosen the special clamp to avoid the electrode rod Fall into the electrode holder);
• Use 240 # sandpaper or grinder to grind the electrode rod, the grinding angle is 30 degrees.
• Put the electrode in the special clamp jaw, pay attention to the length of the electrode, then put the electrode rod into the clamp mouth, tighten the lock nut to fix the electrode rod, and retrieve the electrode clamp gauge;
• Close the light-emitting room door and switch on the light source switch (SOUCRE) on the switch panel. Electrode standardized discharge was then performed.

2.Sweep stage cleaning

• After the instrument has been excited (discharged) 3,000 times, it must be cleaned and maintained.
• Turn off the light source switch (SOURCE) on the instrument panel;
• Open the door of the light-emitting chamber, and take out the electrode rod and electrode holder with special tools;
• After removing the electrode holder, remove the sealing ring, wipe the electrode holder with gauze, do not use sandpaper to polish it;
• Take out the sealing ring on the electrode holder, wipe the electrode holder mouth, sealing ring and gasket with absorbent cotton or gauze, and put the vacuum silicone grease on the sealing ring into the corresponding position;
Note: Frequently used gaskets have front and back sides that cannot be reversed.
• Use 240 # sandpaper or grinder to grind the electrode rod, the grinding angle is 30 degrees.
• Wipe clean the dirt in the light-emitting stage and the spark chamber with absorbent cotton or gauze;
• Put the electrode holder back on the light stage;
• Put the electrode into the special clamp jaw, pay attention to the length of the electrode, then put the electrode rod into the electrode gap gauge, tighten the lock nut to fix the electrode rod, and retrieve the electrode clamp gauge;
• Turn off the lighting room and turn on the light source switch (SOUCRE). Electrode standardized discharge was then performed.

3.Transparent lens cleaning

• After the instrument is excited (discharged) 3,000 times, the translucent mirror must be cleaned: or when the intensity of Fe1 is lower than 5.5.
• Turn off the light source switch (SOURCE) on the instrument panel. It is also recommended to switch off the vacuum pump.
• Open the door of the light-emitting room, hold the handle, and pull the light-transmitting mirror upward until the lens is visible; • Use a special tool—the lens mounting and dismounting tool, to remove the condenser lens;
• Use alcohol-soaked gauze or camera paper to remove dirt from the condenser lens, and then wipe it gently with a clean, dry gauze; if the dirt is serious, you can wipe it with toothpaste;
• Use a special tool to rotate the condenser lens back to the transparent mirror plate;
• Hold the handle to press down the light-transmitting mirror plate (note: after pulling out the light-transmitting lens, do not press down the frame without the condenser lens);
• Close the light-emitting platform door and turn on the light source switch and vacuum pump switch.




4. Control of electrode gap

• After the instrument is excited (discharged) for six months, the gap must be readjusted: • Exit the operating system, turn off the power of the computer host, the power of the vacuum pump, and the light source on the instrument panel (SOURCE). Drop);
• Open the protective plate of the light source room, take out the electrode rod on the electrode holder, and grind the electrode rod with 240 # sandpaper or grinder, the grinding angle is 30 degrees.
• After grinding, put an electrode length gauge on the electrode holder, with the leftmost end near the electrode holder;
• Put the regeneration electrode or new electrode on the electrode holder, the tip of the electrode rod is close to the electrode gauge, and then tighten the screw;
• Remove the electrode gauge and lock the panel;
• Close the light-emitting platform door, and turn on the light source switch, vacuum pump power, and computer system power.

5.Cleaning of fan and heater for temperature control

• After the instrument has been excited (discharged) for one year, it must be cleaned.
• Exit the operating system, turn off the power of the host computer, the power of the vacuum pump, the light source switch (SOURCE), the temperature control switch (AIRCON), the control switch (CONSOLE), and the main power switch (MAINE) on the instrument panel.
• Take off the front panel of the instrument and clean it with a vacuum cleaner. Note: The action should be light, do not damage the circuit board, and pay attention to safety.
• Install the panel, start in the order of startup, and work after the temperature stabilizes at 40 degrees.

6.Vacuum pump oil replacement

• The oil needs to be replaced after the instrument has been excited for half a year or when the oil level is below the standard line.
• Turn off the vacuum pump switch (red button STOP) and turn off the argon vent valve switch;
• Unscrew the oil inlet lock nut and oil drain oil lock nut on the vacuum pump;
• Let the oil drain from the drain port. During the draining process, the vacuum pump switch can be started for a short period of time to allow the vacuum pump to run for a short period of time to allow the oil to drain cleanly;
• After draining oil, tighten the drain port nut and add new oil from the fuel filler (note during refueling: refill to the standard oil level, do not add too much or too little);
• After refueling, tighten the oil port lock nut;
• Unscrew the argon vent valve and start the vacuum pump switch (green button START).

7. Lamp test

• On the content analysis screen, press Shift + F1 to enter the function menu and select maintenance;
• Press ENTER to enter and select device maintenance;
• Press ENTER to enter, select lamp test, press ENTER to enter;
• Press the F1 key for the lamp test until the test is completed;
• Check the test results and check the [MVC] value. It is required that the value of all elements is less than 0.1. After meeting the requirements, press F9 to return to the content rate analysis screen. If there is an error, check it until it is checked.
