Shanghai Weiming Intelligent 32 Stage Temperature and Humidity Measurement and Control Instrument

Shanghai WeimingIntelligent 32 stage temperature and humidity measurement and control instrument

The instrument adopts the most advanced single-chip microcomputer as the host, reducing peripheral components and improving reliability; Adopting fuzzy theory and traditional methodsPIDThe control method combining control enables the control process to have the advantages of fast response, small overshoot, and high steady-state accuracy. It is a high-performance, highly reliable, and fully input fault-tolerant temperature control instrument, with its functionsJLSuitable for all temperature measurement and control scenarios, and compatible with other three industries: industrial parameter measurement and control.

The Use of Shanghai Weiming Intelligent 32 Stage Temperature and Humidity Measurement and Control Instrument

1. Start work(runPower on):

Stop it(Bottom rowSPalternate displaystopAnd the set value)Or pause(SPAlternating display in the lower rowHOLDAnd the set value)In state,Press and hold the temperature or humidity gauge▼ Key2second,The instrument starts the program timing work immediately(Bottom rowSPalternate displayrunAnd the set value),at this timeA-MThe indicator light is on. Are the heater and humidifier working,Still comparing the original settings with the current measured values,Decide whether to connect or disconnect.

OUTIndicator light on,Heater or humidifier connected for operation,

OUTThe indicator light is off,Heater or humidifier disconnected for operation

After completing multi-stage work,The instrument is in a paused state,

exist7Within the day,Press the ▲ key2second,Restore the instrument to a stopped working state.

2.Suspend work:

In the running working state(A-MIndicator light on). Press and hold the temperature or humidity gauge▼ Key2second,The instrument will temporarily stop timing,(Bottom rowSPalternate displayHOLDAnd the set value),But are the controlled heaters and humidifiers working,Still comparing the original settings with the current measured values,Decide whether to connect or disconnect. Just stop timing.

at this timeA-MThe indicator light is flashing

3.stop working:

Press and hold the temperature or humidity gauge▲ Key2secondControlled byThe heater and humidifier stop working simultaneously,(Bottom rowSPalternate displaystopAnd the set value), at this timeOUTThe indicator light is off, A-MThe indicator light is off.
