The
residual chlorine online analyzer can measure residual chlorine and total chlorine in water, and has the characteristics of simple operation and high sensitivity. It is widely used in on-site rapid detection of water quality in the fields of urban water supply, food and beverage, environment, medical treatment, chemistry, pharmacy, thermoelectricity, papermaking, aquaculture, bioengineering, fermentation technology, textile printing and dyeing, petrochemical industry, water treatment, etc. How to diagnose when a fault occurs? 1. The tapping hand pressure method often encounters the phenomenon of good and bad when the instrument is running, most of which are caused by poor contact or virtual welding. In this case, tapping and hand pressing can be used. The so-called 'knocking' is to gently tap the plug-in board or components with a small rubber head or other knocking objects on the parts that may fail to see if it will cause errors or shutdowns. The so-called 'hand pressure' means that when a fault occurs, turn off the power and re-press the inserted parts, plugs and seats by hand, and then try to turn on the power to see if the fault will be eliminated. If it is found that it is normal to knock on the case once, and then it is not normal, first reinsert all the connectors firmly and try again. If the brain is not successful, you have to find another way. 2. Observation uses sight, smell, and touch. Sometimes, damaged components will discolor, blister or burnt spots; burnt out components will produce some special smells; short-circuited chips will become hot; weak soldering or desoldering can also be observed with the naked eye . 3. The comparison method requires two instruments of the same model, and one of them is in normal operation. This method also requires necessary equipment, such as a multimeter, oscilloscope, etc. According to the nature of the comparison, there are voltage comparison, waveform comparison, static impedance comparison, output result comparison, current comparison, etc.
