This is the calibration of the machine's "normal machine calibration three months once> Calorimeter anti Standard 123 steps above. 4 on the heat press machine, enter the weight, and then heat, the machine began to work automatically print the results in fifteen minutes. Results should come out with the actual results benzoic contrast, the error should not exceed more than 50 cards measuring range of coal calorific 1 said sample  2 crucible into oxygen bomb, ignition Szymborska the oxygen bomb, ignition wire resting on cotton thread and then connect to the coal, the added ten milliliters of pure water equipment aerobic bombs, filled oxygen 3Mpa fifteen seconds. 3 into the machine 4 on a machine press Set. Hydrogen sulfide into the water, and then the sulfur content of the hydrogen digital number to lose if the actual value. After transmission, press the Set button to exit ,, must retreated original interface, then heat the key, enter the weight of the coal, and then heat button, the machine began to work, fifteen minutes to print the results. Failure Case calorimeter of an ignition failure of the three pillars of a first check the fuse insurance is usually on the back of the machine under 2 Check oxygen bomb, the igniter cap on  is rusty, such as rust can cause poor contact, use sandpaper to rust. 3 Check whether the oxygen bomb ignition wire clamp, thread is connected, whether enough oxygen punch, or if there is no point will result in failure. 1 bomb dioxide leaks mainly to check damage to seals, the machine a total of four seals. 2 laboratory personnel due to the commissioning and installation personnel to learn four kinds of seals removable and the location. 1 First machine maintenance to protect the environment of health 2 put the machine cover is open, keep the machine at low temperature drying 3, to keep the water inside the machine can freeze 4 on the oxygen bomb should not open storage, keep dry.
