When the skirt was off presidential Hua Dewei CTH1000 carbon monoxide detector is designed for industrial environments often present CO gas safety testing equipment, prevention of gas poisoning, the use of embedded microprocessor intelligent control, operation is very simple, but the face of some operations Small problem, glitch, often feel difficult, below the device prone Hua Dewei few glitches do an analysis for your reference. 1, start the instrument can not be switched problem, there are three reasons: switch failure, the battery lead is broken, a serious shortage of battery power. You can troubleshoot these three aspects. Only a decimal point after the boot screen, the sensor may be bad; if only one negative wireless security system number, it may be a power failure or output short circuit. 2, detection of problems If no response, the sensor may be bad, it could be the absence of CO gas atmosphere. If the concentration is not overrun alarm. Xiangqi is either bad, or is the alarm line break. 3, precision wireless security system instrument calibration problems adjusting to standard calibration gas sample cause unsuccessful, probably because the sensor is broken or outdated, needs to be replaced, if not, there may be serious cause dust proof cover. If you can not solve the problems in the course, please call our customer service hotline: 027-87120545, I will provide the best service.
