5. Introduction

BBSW-301 thermostatic water bath shaking table is a biochemical instrument with temperature controlled thermostatic water bath and oscillator, which applies for Oscillatory culture of various liquid and solid compounds such as biology, biochemistry, cell and bacteria in many fields as schools, hospital, petrochemical industry, petrochemical industry, environment monitoring and so on. It's a necessary laboratory instrument for research, education and industry in the field of plant, biology, microbiology, genetic virus, medicine, environmental protection and so forth.

Its feathers are as followings:

• Unique and novelty in appearance, small in volume and powerful in functions. It has strong corrosion resistance because all its surfaces connecting with water are made of high quality stainless steel.

• TFT LCD holographically displays the running speed, temperature and time. It's clear to see graphical symbols and exact data.

• Memory storage mode with built-in chip, which has nine kinds common parameter combinations and single - node cycle or multi-node pulse cycle can be realized as well. Meet more experimental requirements

• Microcomputer program PID automatically controls temperature, which has good temperature uniformity, high temperature control accuracy and comprehensive safety protection.

• Oscillation and heating are designed separately. Users can take off moving frame when oscillation is not required. And then the instrument can be used as thermostatic water bath, which realizes one camera dual use.

• Direct current motor, low noise, no maintenance and long service life.

• Transparent and flip type cover design makes easier operation and better observation of internal running situations. The v-type heat cover can prevent water drop from dropping into the flask.

7.3 Operating instructions

left : In setting mode, press down the knob to switch cursor position, only for

setting temperature and time. Turn the right knob to increase the number at

the setting .Turn to the left is the opposite situation.

right : Turn the right knob to increase speed. Turn to the left is the opposite situation.Press the knob to start operation. Press the knob again to stop operation.

Press the button to select single node from S1 to S9. Each node stores different running parameters separately,Each node stores different running parameters separately. This

button is a program selection key of single - node.

Press the button can circularly set temperature, time, and multi-node parameters. At

the same time, turn the left knob to move the cursor and add or subtract the value to finish parameter settings.

7.4 Power connection

Put the instrument on a firm and level table. Insert the cylindrical jack of the power cord into the power input jack at the back of the instrument as the picture shows. And connect the other end of the power cord to the grid whose voltage requires AC110V/AC220V

8. Operation Guide

1. Setting of speed, temperature and timing time

Turn on the power switch, the display will light up and holographically displays various parameters of the instrument into initialization, meanwhile with the sound of "di".

Set speed quickly and immediately: Turn the right knob and set the speed value immediately. Stop turning the knob, the instrument will automatically confirms the implementation of the new set value and saves it, just as the right picture shows. If increase of modification range is needed, just turn the knob quickly.

Figure 5

2. setting temperature: press key, The temperature parameter frame changes from colorful

one to white one and enters the setting mode. At this point, the temperature value is the setting value of the last time, and the cursor flickers at the end. Turn the left knob to increase or decrease the current cursor value. Press the knob to move the cursor forward and set the leading digit. Stop turning the knob, the instrument will automatically confirms the

implementation of the new set value and saves it, just as the right picture shows. If increase of modification range is needed, just turn the knob quickly.

Figure 6

3. Setting timing time :press key, The time parameter frame changes from colorful one to white one and enters the setting mode. At this point, the time value is the setting value of the last time, and the cursor flickers at the end. Turn the left knob to increase or decrease the current cursor value. Press the knob to move the cursor forward and set the leading digit. Stop turning the knob, the instrument will automatically confirms the implementation of the new set

value and saves it, just as the right picture shows. If increase of modification range is needed, just turn the knob quickly.

Figure 7

Attention: when time setting shows 00:00, it means time running value as ∞.

4. Operation and stop

• Click START/STOP (right knob) can run the current program. The timing ends, the operation will stop and the buzzer calls an alarm.

• After the operation finished, the instrument waits for the instruction and the time parameter displays "OVER". Press any key can restore the initial state. Press the START/STOP button directly, and the program can start with the speed and time parameter of last time setting.

• During the operation, pressing START/STOP key for a little time can stop the operation. If press START/STOP key again, program will start as well.

• If operation starts at the situation of the temperature is set, it needs to be heating to the set

temperature before blending. Please wait for a moment.

• In the process of temperature heating, the indicator light in the screen temperature parameter icon will flash and long light after reaching the set temperature.

5. Node and programming mode

• Single node: The built-in chip of the instrument can remember nine kinds

parameter sets from S1 to S9 which can display circularly with one key '. Click the START/STOP key (right knob) can run the current program. Users can store common parameters into the instrument for easy operation.
