Set temperature: press and hold the SET key, at this time the tube character begins to flash, proving that the instrument has entered the set state, increase the up button, decrease the down button, and press and hold the up and down buttons to quickly change, when the desired temperature is reached, then press the SET button The instrument is set. 2. Return control: press SET ...

The level gauge is composed of five parts: float, traction cable, guide pulley, hammer pointer, display ruler or magnetic flap. 1. Float: The float is welded with two stainless steel (or carbon steel) fasting cones and one stainless steel (or carbon steel) fasting cylinder.

After heating for a while, the temperature does not change. Displays the ambient temperature of the site at all times (e.g. room temperature 25°C) In case of such a fault, first check whether the SV value setting value is set, whether the OUT indicator of the meter is lit, and whether the No. 3 and No. 4 terminals of the meter are 12VDC output with the "multimeter". ...

1. The principle of central air conditioning thermostat Mechanical thermostats can be divided into vapor pressure thermostats, liquid expansion thermostats, gas adsorption thermostats and metal expansion thermostats. Among them, the vapor pressure thermostat is divided into inflatable type, liquid-gas mixed type and liquid-filled type. Domestic...

In a variety of electronic control equipment, digital display has become an indispensable and important link.
