HH series constant temperature water bath pot

1、 This oneThe company adopts 304 # high-quality stainless steel for one-time stretching forming. Replace the original product welding process. Ensure that the product leaks during long-term use. The four corners and bottom of the product are designed in an arc shape, which makes it difficult to create dead corners during the heating process and affects the uniformity of water temperature. The instrument casing also adopts a one-time drawing and extrusion forming process. The outer shell is made of cold-rolled sheet surface sprayed with plastic, and the four corners are designed with outer arcs, which not only looks beautiful and elegant, but also improves the instrument's resistance to falling and compression during use and transportation, and is easy to clean. Can be widely used in chemical, medicalgive birth toIndustries such as physical experiments.

3、 Usage:

a) When using, water must be added to the pot first, and then the power should be turned on.Set temperature:Press the SET key to set or view the temperature set point. Press the SET key once and the digital display character will start flashing, indicating that the instrument has entered the set state. Press the Δ key to increase the set value, press the ▽ key to decrease the set value. Long press the Δ key or ▽ key to quickly change the data. Press the SET key again and the instrument will return to normal working state. The temperature setting is complete.

b）Advance setting:Press the SET button for 3 seconds to enter the inner layer parameter setting state of the instrument. The first parameter that appears and flashes is EOO, which is the advance amount of heating stop. The advance amount parameter should be adjusted carefully to reduce temperature overshoot. When the instrument controls the heating output, it will cut off heating in advance. When the temperature drops below the advance amount, it will start heating again. The output (relay) will not operate within the set value and advance amount range, which can reduce the number of relay actions and extend the relay life. Example: If the set value is 50 ℃ and the advance amount is 0. 5. The instrument controls the heating to 49. At 5 ℃, the relay releases and the temperature drops to 50. 0 ℃ -0. At 5 ℃, the relay closed again. The larger the advance amount, the fewer times the relay will act. If the advance amount is too large, it will reduce the accuracy. After adjusting the advance parameter, press the SET button for 3 seconds to return the instrument to its normal working state.

c）Correction of errors:When confirming that the value displayed on the instrument is not the correct measurement value, the displayed value can be adjustedCorrection.Press the SET key for 3 seconds to enter the inner menu of the instrument panel,. The first parameter that appears and flashes is EOO, which is the advance amount. The parameter that appears and flashes when the SET key is pressed again is the error correction parameter, which can be modified by using the Δ or ▽ key. The range of error correction is from -9.9 ℃ to+9.9 ℃. After completing the correction, press the SET button again to exit. The correction value of the instrument is 0 when it leaves the factory. When using, it is important to prevent correcting instruments that display correctly to incorrect ones.

Do not add too much water to the pot to prevent it from overflowing when boiling, and be careful not to expose the electric heating tube to the water surface inside the pot to avoid burning out the electric heating tube and causing water leakage.

fourPrecautions

(1) To ensure safety, please connect the ground wire when using.

(2) It is strictly prohibited to dry burn without adding water.

(3) When not working, the power should be cut off to prevent accidents.
