1. First of all, the digital display should be installed on the cabinet, so the overall coordination should be considered, too large may not fit, too small to see the display numbers.
2. In addition, large instruments generally have strong functional scalability, and the price of the same function may be expensive, and small instruments may have poor functional scalability.
3. Data increment button ù: Press this button in the measurement state, and the display will display the upper limit value for about 5 seconds. Pressing this key in the setting and calibration state will increase the number of the current blink bit by 1.
4. Data reduction key U: Press this key in the measurement state, and the display will display the lower limit value for about 5 seconds. Press this key in the setting and calibration state to decrease the number of the current blink bit in increments of 1.
5. Set key PAR: used for setting parameters such as upper and lower limits, data shift key ÷: press this key when setting parameters to change the current input digits

RKC Thermostat The structure, action principle and use of some commonly used relays
A relay is an electrical appliance that works automatically. When the amount of electricity such as voltage, current, and frequency or non-electricity such as temperature, pressure, and rotational speed is input to the relay, and when the specified value is reached, the contacts of the relay connect or cut off the circuit that controls or protects it. Relays are widely used in motor control and power ...

RLC Thermostat – The reason why the temperature control meter shows HHH
The reasons why the temperature control table shows HHH are as follows:
1. The thermocouple signal line is reversed, or short.
2. If the temperature control meter is in normal use before, it is recommended to check whether the signal line of the thermocouple is broken.
3. The wire inside the thermocouple is broken.
4 ...
