Instrument Installation:

Open the packing case, you will see the three parts of the instrument, i.e. controller, furnace body and purification absorber.
1、Furnace body installation: First install the silicon carbide tube. Be sure that the two sheet metals are 3mm away from the edge of silicon carbide tube. Put two ceramic pads in the middle of the sheet metal for preventing short circuit and silicon carbide tube damage.?
Correctly position the ceramic pads of the screw, or else short circuit may be caused. Then fasten the screw. The screws on both sides shall be simultaneously fastened with the same space kept. The degree of screw tightness must be proper. If too loose, sparking may occur, if too tight, the silicon carbide tube may break. The best practice is to refasten them after one month of use, or add a screw cap between the sheet metals. Then screw the wires of the two silicon carbide tubes and secure them with screw cap. If the insulation bowl is loose, screw the wire to tighten it until there is no space. Avoid bare copper wire from electric leakage.
2、Take down the left round shied to see whether there are sundries in the furnace body and whether it is clean. Then feed the silicon carbide tube into the furnace body until it can not move forward. Then slightly lift it up to movie it inward more until it is on a step. Then install the left shied and fasten its screw while shaking the silicon carbide tube to prevent blocking and breaking the latter. Ensure that after 4 screws are tightened, the silicon carbide tube is also movable. Then insert the reducing pipe, also slightly lift it up to move it inward more onto the step. Then fasten the left retaining screw to secure the reducing pipe. Also pay attention that whether the reducing pipe at right feed port is consistent with the furnace body itself. Avoid dislocation, or the sample may be blocked in the experiment.
Connect the wire of thermocouple and screw the several screws of the thermocouples tight. After that, insert the thermocouple into the thermocouple hole in the furnace body. Then lift the silicon carbide tube by hand to see whether the thermocouple moves. If not, it means the thermocouple is not in place. At last, after it is in place, draw it back for 1mm. Fasten the screw to secure it.
3、Installation of purifier and electrolytic tank: Pay attention to the connection order of rubber tubes. The reducing pipe and two-way valve are linked with silicone tube. It would be best to apply vaseline over the two-way valve, so that it will be sealed better. Connect the two-way valve with one of connector with solution plate of the electrolytic tank at one way, and with the purifier at the other way. The bottom port of the electrolytic tank is connected with a section of rubber tube and clamped with a water sealing clip. Both ends of the two drying tubes on the left of purifier are plugged with degreasing cotton with allochroic silicagel in the middle. Screw the rubber plug tight to avoid air leakage.
Preparation of electrolyte: Take 5g of potassium iodide and 5g of potassium bromide, dissolve both in 250～300 mlof distilled water. Then add 10 ml of glacial acetic acid into the solution, mix them until they are completely dissolved. The electrolyte may be used repeatedly. It shall be re-prepared in case of PH<1.

Operating steps:

1、Warming up: Open the feed window on the right side of the instrument and switch on. Then the printer will check itself and the feed motor will reset automatically to be on standby. The instrument will warm up automatically (without manual adjustment). For first use, it would be best to let the furnace warm up to 800℃and keep the temperature for 30min (please use the“Temperorature control”?key on the panel. ). Then switch off and let the furnace cool to the room temperature. Start the instrument again and let the furnace warm up to the operating temperature of 1050℃.
2、Pour into or absorb electrolyte. Open the two-way valve and air pump. Adjust the flowmeter to 1000 ml/min.. Open the mixer and slowly adjust its rotating speed until the bubbles from solution plate are fully mixed with the electrolyte. Then the instrument enters the status of ready for experiment.
3、Take about 50mg±0.2mg of uniformly mixed sample from the porcelain boat. Cover a thin layer of tungsten trioxide over the coal sample. Put the porcelain boat on the quartz tray. Open“Electrolytic switch”press"start"?key, input three-digit sample weight (no need to input digits after the decimal point), press"start"?key again, the sample will be sent to combustion furnace again. Remain at 500℃and 1050℃respectively for the set durations. After then, return and print automatically. The whole experiment is executed by procedure automatically.?
Take down the porcelain boat with tweezers (not by hand). Repeat step 3 for the second sample.
Note:(1)Prepare several waste samples before each test to balance the electrolyte, i.e. the right display window becomes to count, that is to say, the waste sample result is not zero before normal sample testing.
(2)During experiment, the“electrolytic switch” must be switched on, or no electrolysis will occur. It is prohibited to switch on the“electrolytic switch” when the electrolyte mixing is closed. It can only be switched on when the electrolyte is being mixed. Or else, it will pollute the electrode and affect the test precision.
(3)It would be best to carry out the test continuously. If there is a long interval between two tests, an additional waste sample shall be burnt before the latter test.
(4)After the experiment is over, press the“electrolytic switch”and close electrolysis, two-way valve, mixer and air pump. Discharge the electrolyte (best saved in brown grinding jar) for future use. Clean the electrolytic tank with distilled water. Switch off.?

About subsection deviation correction

This instrument can change deviation for each subsection, make the result close to standard value, the process is actual result plus or minus deviation of each subsection, positive deviation, the result will add the deviation of this subsection, negative deviation, the result will minus the deviation of this subsection.
Modification method: input a deviation of each subsection in the window of “subsection correction”, and click “ save”,
? a0 section means the correction range of sulfur content from 0.00%~0.99%
