Instructions for use
â‘ Turn on the power and the self-test will be completed in about one minute. If "000" is displayed, the sensor is open or the input signal exceeds the measurement range.
â‘¡When confirming that the value displayed by the instrument is not the correct measured value, the displayed value can be corrected. Press SET key for 3 seconds to enter the inner menu of the instrument. After selecting the parameter SC, cooperate with the â–³ or â–½ key to modify this parameter. The correction range of the sensor error is 50 to -50. After the correction is completed, press the SET button for 3 seconds to exit. The correction value is 0 when the meter leaves the factory. When using it, it is necessary to prevent the meter with the correct display from being corrected to be incorrect.
â‘¢Press the SET key to set the temperature, press the SET key until the lower row of the code tube flashes, indicating that the instrument enters the temperature setting state, press the â–³ key to increase the set value, press the â–½ key to decrease the set value, and press The SET key returns to the normal working state and the temperature setting is completed.
â‘£The auto-tuning function of the instrument: This product can adapt to most control systems. Only when the control effect is particularly unsatisfactory, the auto-tuning can be started. Press the SET key for 3 seconds to enter the inner menu of the instrument. Press the key to turn on auto-tuning. At this time, the At indicator starts to blink and the instrument enters the automatic tuning parameter working state. The instrument controls the heating system to fluctuate twice near the set point. When the At light is off, auto-tuning ends and the new PID parameters are locked in the chip in.
Classification:
1) According to the vibration method: gyroscopic (laboratory), reciprocating, dual function (gyroscopic and reciprocating)
2) According to the assembly, there are water bath, gas bath and oil bath
Gas bath thermostatic shaker: It is a biochemical instrument with a temperature-controlled thermostatic gas box and oscillator
The water bath constant temperature shaker is a biochemical instrument combining temperature controllable water bath and oscillator
Oil bath constant temperature shaker is a kind of biochemical instrument with temperature controllable oil bath and oscillator
Among them, the temperature control of the gas bath shaker can reach up to 70 ° C, and 37 ° C is commonly used.
The temperature control of the water bath shaker can reach up to 100 ° C
3) According to the oscillation frequency:
There are three common types: 30-200RPM 400-300RPM 60-400RPM
The oscillation frequency reaches 400RPM, because the oscillation frequency is relatively large, so the requirements for the Erlenmeyer flask are high
4) Divided by volume: micro, constant and large
5) According to the constant temperature range: low temperature (5-50 ℃) and normal temperature and high temperature
6) Divided by the number of layers: single layer and double layer
7) According to the number of doors: single door and double door
8) According to the display method: digital display (only numbers can be displayed) and LCD display (display numbers and letters)
9) According to the timing function: timing and normally open
10) According to the placement method: vertical, desktop, stacked., Floor type
11) Whether environmental protection is divided: fluorine-containing and fluorine-free
12) According to heating power: below 999W, 1000W-1999W; above 2000W
13) According to the oscillation amplitude: Φ25mm (commonly used), Φ50mm (large)
14) According to the use of power: 220V 50HZ 240V 50 / 60Hz (United States Thermo)
15) According to the driving mechanism: three-dimensional balanced eccentric wheel drive four-side slide bar driving mechanism
16) Compressor points: imported and domestic, high-quality fully enclosed compressors and air-cooled sealed compressors
17) Amplitude adjustment method: multi-level adjustable stepless adjustable
