meixiang teach you to operate thermostatic oscillator
Digital display thermostatic oscillator instructions:
1 in the speed range of speed, can prolong the service life of the apparatus.
2 instruments should be placed on a more solid work table, the environment should be kept clean and tidy, ventilated and dry, water supply and drainage is convenient.
3 before using the instrument, the speed control knob is put in the minimum position, and the switch is closed ".
4. Fit the training sample flask should pay attention to the following points: (1) uniform distribution; II liquid filling amount not less than normal, prevent the generation of test bottle floating; 3 good sealing test bottle, to prevent condensation of water droplets drops in the bottle.
5 tap water into the tank, the water level should be slightly higher than the inner liquid level of the culture test bottle.
6 switch on the external power supply, the power switch is placed in the "open" position, the indicator light.
7 select the constant temperature:
A. setting temperature: press the SET key to set or view the temperature set point. According to a set key digital tube character start flashing, said instrument set to enter the state, according to] key set value increase, press the button to set value decreases, long press] or button data will quickly change, again press set key the instrument back to normal working temperature after setup and start heating indicator light.
B. ahead of schedule: press SET button 3 seconds to enter the inner parameter settings. First appeared and flashing parameter to stop the advance, advance parameters that have to be carefully adjusted, in order to reduce the temperature overshoot, instrumentation and control the output of the heating will advance stop heating, when the temperature fell to advance the following began to heating, value in the set and weight range output (relay) will not work in advance, reduce the number of relay action to prolong the service life of the relays. Cases: if the setting is 50.0 DEG C, ahead of the amount of 0.5, instrumentation and control heating to 49.5 DEG C when the relay is released, the temperature dropped to 50.0 DEG C - 0.5 DEG C =49.5 DEG C when the relay is attracted. The greater the number of relays, the less the number of relays, the amount of time ahead of the general assembly to reduce the control accuracy. After adjusting the parameters in advance of the amount of SET key 3 seconds to return to the state of the instrument. Note: advance setting is designed to prevent the heat from stopping after the temperature is too high and set the special, generally do not need to modify.
Correction of C. error: the display value can be corrected when the value of the instrument display is not correct. Press the set button 3 seconds into the menu on the inner layer of the instrument, first appeared and flashing parameter E00 that amount in advance, and then press the set button once appeared and flashing parameter error correction parameters, with] or button can modify the parameters. Error correction range of -9.9 to +9.9 degrees Celsius, after the completion of the correction and then click SET button to exit. When the instrument is in the factory, the correction value is 0. When used, it is not correct to correct the instrument to be corrected.
8 select the timing, timing knob to "time" or "open" position.
9 open "oscillation switch", the indicator light, slowly adjust the speed control knob, observe the speed display screen, rose to the required speed.
10 before each stop, the switch should be placed in a non working state, the timer set "zero", cut off the power supply.
11 to prohibit the use of water in the tank water heater. If the device is disabled for a long time, the water in the tank should be excluded and dry with a soft cloth.
