Table 2-4 Pump head / tube model and corresponding maximum flow reference
Note:

1. Please refer to the flow chart in Chapter 6 before selecting the proper pump head and tube.
2. The tube of the same size but different materials with different ductility, resilience and hardness will lead to difference of flow rate, so the maximum flow rate is only for reference.
3. When using a tube with thicker wall (such as 24# tube), the current can be set to be larger, so as to increase the torque of the pump at high speed.
4. When using a tube with thicker wall (such as 24# tube), the pump might be stalled when it starts at high speed after stopping working for a period of time. It is necessary  to add lubricating oil and work at low speed for 1 to 2 minutes.

3.2 Working Mode Description
3.2.1 Calibration Mode
After the instrument is used for the first time, or after the pump head or pump tube is replaced, in order to obtain an accurate liquid volume result, it is necessary to perform a “calibration” operation and input the calibration result. The specific calibration process is as follows:

1. Determine calibration speed. According to the flow rate you need, query the flow curve of the corresponding pump head / tube (Chapter 6 flow curve) to obtain the  approximate calibration speed.
   Take YZ1515X-6 wheel and 16# tube as an example. If you need a flow rate of 175ml / min, find the approximate position of 175ml / min on the longitudinal axis,  make a horizontal line intersecting with the red line of the flow curve of the 16# tube, make a vertical line from the intersection point to the horizontal axis, and the  intersection point with the horizontal axis is the calibrated target speed (about 275rpm).

2. Edit calibration parameters. On the calibration editing interface, input the calibration speed and calibration time, set the liquid volume to 0, and press the “Enter” key to  save.

3. Perform calibration process. Press the “CW/CCW” key, select the required steering direction, pre fill the tube, and empty the liquid in the receiving container. In the  calibration standby interface, press the “ON/OFF” to start the peristaltic pump. After running the “calibration time”, the dispensed liquid volume is the ” volume” of  this calibration. Use the measuring cup to read the milliliter of dispensed liquid.

4. Input calibration data: after calibration, press the “Edit” to input the above calibration data (ml of liquid volume), and press “Enter” to save. After that, the system will  automatically return to the main interface. When saving, if it displays “maximum flow overflow default value!”, you need to check the calibration process again to see if  the test value is wrong.
   Note: The calibration time of the pump is 60 seconds by default. You can also extend it appropriately. Repeat the test for many times to obtain the average value of the  liquid volume obtained from multiple calibrations, which can improve the accuracy of the calibration results.

3.2.2 Inquiry Mode
Parameters such as standard speed, standard flow, minimum flow, maximum flow and standard ratio can be queried.
3.2.2.1 Calibrated speed
Last calibrated speed value. The default is 100.0 rpm
3.2.2.2 Standard flow
After the calibration, the system automatically calculates the calibrated flow under the correct input of the calibrated speed and the liquid volume value under the fixed time.  Flow unit: ml / min.
3.2.2.3 Minimum flow
According to the calibrated speed, minimum speed (0.1 rpm) and calibrated flow, the system automatically calculates the minimum flow
3.2.2.4 Maximum flow
According to the calibrated speed, maximum speed and calibrated flow, the system automatically calculates the maximum flow.
3.2.2.5 Calibration ratio
Calibration ratio = calibrated flow / calibrated speed. Calibration ratio unit: ml / r. This is a reference unit for calculation.
3.2.3 Setting Mode
Parameters such as maximum speed, one key full speed, backlight time, contrast, current code and foot switch working mode can be set on the editing interface.
3.2.3.1 Maximum speed
It is the upper limit of motor speed. The maximum speed of the pump is generally related to the pump head model / pump tube model, which generally does not need to be  changed. If the maximum speed is changed, it is necessary to recalibrate and input the calibrated value correctly.
3.2.3.2 Full speed
That is the speed of the motor when the motor is on the standby interface and press the “full speed” key. This function is generally used for emptying / filling. In order to  ensure the stable running of the pump, the full speed is generally lower than the maximum speed.
3.2.3.3 Backlight time
This is the retention time after the backlight is turned on, in second (SEC). Each time you press the new key, the backlight retention time is recalculated.
3.2.3.4 Contrast
Contrast is used to adjust the brightness of the LCD screen.
3.2.3.5 Current code
The current code is used to set the maximum current of the motor.

Definition table of current code as below:

Motor does not rotate| The screen shows that the motor works. In fact, the motor does not rotate.| Check whether the pump body joint is loose and reliable.
---|---|---
Check whether the current code in “settings” is too small. Set the current code consistent with the product.
The motor connecting wire is loose and return to the factory for repair.
Power wire is loose and return to factory for repair.
Motor stalled| The original pump head / tube can run at a certain speed, but the new pump head / tube cannot run.| The new pump head / tube should be run for one or two minutes at a lower speed.
The maximum speed of the motor suitable for the pump head / tube is exceeded.| Please refer to the above operation curve to select the reasonable speed corresponding to the pump head / tube.
Inaccurat e flow or liquid volume| There is a big difference in the liquid volume or flow rate after replacing the tube.| Recalibrate and input accurate calibrated parameters.
You can take the mean value after multiple calibrations, and then enter the mean value.
The tube has been used for a long time and its resilience has decreased| Replace the tube.
Accuracy requirement is not appropriate.| The flow rate / speed / tube diameter are inversely proportional to the accuracy. Try to use smaller diameter tube.
