1 Shanghai Weiming Temperature and Humidity Measurement Control Printing Instrument

summary:

This series of temperature and humidity controllers adopts advanced production technology to ensure the stability and reliability of product quality. It uses dual row digital tubes to display moderate measurement values and dry temperature measurement values respectively. At the same time, the instrument has the following multiple functions for users to choose from:

1Sensors: can be measured separately through parameters,Select UsePT100+Polymer or wet dry dualPT100sensor(Need to replenish water).

2Control mode: Heating and humidification output are availablePIDUsers can choose between control or binary control, and the cooling system can be equipped with a delayed output function.

3Serial communication: The instrument can be installed throughRS485The computer serial communication module communicates with the computer to achieve remote control of instruments. useMODBUS RTUCommunication protocol.

4Printing function: Alternatively, the instrument can be equipped with a printing module that can be connected to a micro printer to print and record temperature and humidity sampling values at regular intervals.

Instrument operation:

3.1. Connect the instrument correctly according to the instrument wiring diagram and power it on. After the instrument passes through1SAfter the self check time, it will enter the normal display state, where the upper digital tube displays the measured humidity value and the lower digital tube displays the measured temperature value.

3.2Superior menu settings:Press and holdSETkey3SEnter the parameter modification state, where the upper row digital display shows the parameter symbol and the lower row digital display shows the parameter value. Press the ▲ or ▼ keys to modify the current parameter value, and long press the ▲ or ▼ keys to quickly add or subtract data. After the modification is complete, press againSETKey to save and enter the next parameter modification state, if during the setting process10SIf there is no operation inside, the instrument will automatically save the settings and exit the parameter modification state.

3.3Secondary parameter (printing parameter) settings:Press and hold simultaneously in normal display modeSET+▼+▲ key, the instrument enters the printing parameter modification state, and the modification method is the same as“5.2High level menu settings.

3.4Quick exit:In the state of modifying parameters at the upper level,Simultaneously pressSET+The ▲ key immediately exits the parameter modification state.

Control instructions:

4.1Heating control:

When parametersP1=0time

Temperature measurement value ≥C1＋HY1At this time, the heating indicator light on the panel is off and there is no heating control output;

Temperature measurement value ≤C1－HY1At this time, the heating indicator light on the panel is on, and there is a heating control output;

C1－HY1<Temperature measurement value<C1＋HY1At this time, the instrument is heated back to the differential control area.

When parametersP1≠0When the instrument is heated, it is executedPIDControl.

4.2Humidification control:

When parametersP2=0time

Measure humidity value ≥RH＋HY2At this time, the humidification indicator light on the panel is off and there is no humidification control output;

Measure humidity value ≤RH－HY2At this time, the humidification indicator light on the panel is on, and there is a humidification control output;

RH－HY2<Measure humidity value<RH＋HY2At that time, it is the humidification return differential control area for the instrument.

When parametersP2≠0When the instrument humidification is executedPIDControl.

4.3Refrigeration output:

Temperature measurement value ≥C2＋tbAt this time, the cooling indicator light on the panel is on, and there is a cooling control output;

Temperature measurement value ≤C2－tbAt this time, the cooling indicator light on the panel is off and there is no cooling control output;

C2－tb<Temperature measurement value<C2＋tbAt that time, it is the instrument cooling return differential control area.
