Two, structure description
this equipment is composed of chassis, temperature control instrument, power supply, heating switch, novel appearance, simple structure, simple operation, convenient.
Three, the scope of application
the water bath is suitable for curing and boiling all kinds of specimens at room temperature at -100℃. the temperature control range is used above the normal temperature condition. It has the advantages of fast heating speed, low noise and high precision of constant temperature. Widely used, it is an indispensable equipment for testing and testing units.

2. Precautions during installation
2.1. the equipment shall be placed at room temperature from -10℃ to 30℃; the relative humidity should not be higher than 80% indoors. the room should have good ventilation.
2.2. Pay attention not to knock against the box and components when unpacking.
2.3. It is recommended to use air switch with leakage protection for the power supply of the equipment, so the equipment is not equipped with power plug when leaving the factory.
2.4. the equipment shall be placed on the flat ground, and the four feet at the bottom of the equipment shall all touch the ground and exert even force.
2.5 the device must be well grounded.
3. Product calibration is accurate
this product can be used only after qualified inspection and calibration by a unit with national verification qualification. the verification method is as follows:
3.1. the tester shall have the qualification of verification.
3.2 Verification conditions shall be carried out under the constant temperature of the product.
3.3. 3-5 (or more) standard thermometers should be selected during inspection. Insert standard thermometers into the representative parts of the water bath with olivier (note: do not insert under the olivier)
4, read the temperature value above each standard thermometer and calculate the average.
5, long press the SET key for 3 seconds, when the temperature display window displays LC interface (LC00 is not locked; When LC01 is used to lock the inner layer parameters of the instrument; LC02 is to lock the SET value and instrument inner layer parameters), then press the set key to enter the C interface (temperature correction parameter interface: if 000 is displayed after C, it is the initial parameter). Then adjust the temperature display temperature according to the average value of the standard thermometer. If the average value of the standard thermometer is higher than the display temperature of the temperature control meter, 1.5 degrees should be subtracted from the original value of the "SC" interface, otherwise 1.5 degrees will be added. Accurate to 0.1℃.
6. Long press the SET key to return after setting. Observe whether the temperature displayed by the temperature control meter is consistent with the average value of the standard thermometer. If there is any error, continue to adjust it according to the above operation process until it is consistent.
Chapter four: Use method and matters needing attention
1. Preparation
2.1 Add an appropriate amount of water to the working room, and it is advisable to just soak the tray support.
2.2 Switch on the power supply and turn on the power switch.
2.3 Set the temperature you say you need to set.
2. Use method
2.1 the prefabricated asphalt concrete samples (or other specimens) are arranged neatly on the supporting plate inside the studio, and then water is added to the working room so that the water will soak the specimen and be about 30mm higher than the specimen.
2.2 Turn on the heating switch and the instrument will automatically control the heating process.
2.3 When the heating temperature rises to the required control temperature of the thermostat, record the time when the instrument stops heating and the temperature is constant.
2.4 the specimen shall be used after the temperature in the water tank is constant for at least 30 minutes.
2.5 after the test, turn the hot water valve at the bottom of the tank to drain the water in the tank, wipe the water on the surface of the instrument, and place the instrument in a dry and ventilated place.
3. Precautions in use
3.1 Check whether the device works properly.
3.2 the device must be well grounded during use.
3.3 in case of water leakage and electricity leakage, please cut off the power supply and stop using it.
Chapter five: equipment maintenance knowledge
1. Check before use
1.1 Check whether the power supply of the device is normal. Do not start the device if the voltage is too low or too high.
2.2 Check whether there is leakage.
2.3 Check whether the device works properly.
2. Maintenance after use
after the test, turn the hot water valve at the bottom of the tank to drain the water in the tank, wipe the surface of the instrument and place the instrument in a dry and ventilated place.
