Needle flame test machine calibration operation: ① to measure flame temperature measurement range of room temperature ~ 1200 ℃; ② fixture with the test chamber shelves with alligator clips to the copper block thermocouple clamped; ③ adjust measured according to standards Distance temperature copper block and the combustion tube; ④ Connect the power switch, press the "Stop holding burning" button; ⑤ lit the flame, when the temperature rose to 100 ℃, press the "calibrate" button "Shi Yan time" time ⑥ automatic timing starts when the temperature rises to 700 ℃, the timer will automatically stop the clock and keep, please record timer (thermometers have been set up at the factory parameters, please do not adjustable); ⑦ next When tests, must wait until the temperature drops below 50 ℃, and then repeat the above operation. Needle flame tester used: When you pay attention to the gas loop ① test for leaks, such as joints, trachea is sealed to prevent accidents and affect needle flame; ② high degree of stability. After the test, the tank must be removed! Periodic checks on the gas loop; ③ power applications have ground three pole socket ensure reliable grounding; ④ Input Power AC220V ± 10%; ⑤ exhaust pipe should pass out of the window; ⑥ every start of the test, pay attention to the flame adjustment valve to a minimum, so as to avoid the ignition control.
