The constant temperature and humidity box can reach the cycle change between the specified temperature within the specified time in the test work space, and the humidity is required to meet the requirements within the specified range to produce condensation. Because there are thousands of parts in the constant temperature and humidity test chamber, the equipment may not be able to be humidified due to the failure of some parts. Exclusions and solutions:
Failure phenomenon: unable to humidify
Troubleshooting and solutions:
Failure analysis 1: Whether the connection is good or not Solution: Reconnect
Failure analysis 2: whether the meter display is normal / whether there is output solution: repair / replacement
Failure analysis 3: Whether the instrument setting is correct Solution: reset
Failure analysis four: whether the humidification switch is on / whether the contact is good / whether it is burnt or damaged. Solution: on / maintenance / replacement
Failure analysis five: Does the actuator (contactor, relay, thyristor, solid state relay) have an output solution: replace
Failure analysis 6: Whether the heating tube of the actuator is burnt or damaged
Failure analysis 7: Whether the water supply system is normal / whether there is a water cut indication Solution: adjustment / maintenance
Failure analysis 8: Whether the display / control of the uncontrolled humidification instrument is normal. Solution: repair / replacement
Failure analysis 9: Is the meter setting correct / is it manual output? Solution: reset
Failure analysis ten: whether the actuator contactor, relay contact is stuck or burnt out / whether the thyristor and solid-state relay are broken
Failure analysis 11: Whether the heating tube of the actuator is on the ground Solution: repair / replacement
Failure analysis 12: Is the slow heating instrument setting correct? Solution: reset
Failure analysis 15: Is the humidification slow meter setting correct? Solution: reset
Failure analysis 13: Whether the total resistance value of the heating component is normal / whether there is a short circuit, open circuit Solution: repair / replacement
Failure analysis 14: Whether the blower system is running normally / whether the steering is correct Solution: adjustment / maintenance
Failure analysis 16: Is the total resistance of the humidification component normal / has there been a short circuit or open circuit Solution: repair / replacement
Trouble analysis 17: Whether the water supply control system is normal / whether the float is leaking Solution: repair / replace
