Press , to move the cursor to “Needle tubing size”。5.2.2 Needle tubing size when the cursor is moved to “Needle tubing size”, press or, Needle tubing size are displayed in turn. Press to move the cursor to the next line。5.2.3 TestCountwhen the cursor is moved to “TestCount”, Pressor, 8times, 13times, 20times are displayed in turn5.2.4 Modewhen the cursor is placed over “Report Mode” , the system default is print mode, press to move the cursor to the next line5.2.5 Perform Test when the cursor is moved to “ Perform Test”, Press to move the cursor to the next line. After the testing needing tubing is installed, you can press to enter the test mode, please see the chapter 5.3 for detail operation5.2.6 Move Up when the cursor is moved to “Move Up” Press the apparatus stand will move upward, and the screen will display “Press Enter to stop”, at this point, you can press“Enter”key to stop the move of apparatus stand ，Press the stand can move upward again. Press to move the cursor to the next line 5.2.7 Move Downwhen the cursor is moved to “Move Down” Press the apparatus stand will move downward, and the screen will display “Press Enter to stop”, at this point, you can press“Enter”key to stop the move of apparatus stand ，Press the stand can move downward again. Press to move the cursor to the next line5.2.8 TimeWhen the cursor is moved to “Time”, you can set the system time. Press in a row to move the cursor over the digits of time in turn. Press to change the digit which be selected by cursor. Press to save the time you have set. Pressto move the cursor to the next line5.2.9 System ParameterWhen the cursor is moved to “System Parameter”, Press You can enter the parameter set mode which need a password to enter (you need to contact the vendor to get a password). Press to move the cursor to the next line.5.2.10 Verify When the cursor is moved to “Verify” Press to enter the verifying mode, you can verify if the measured values are accurate by using standard weights, If the numbers displayed on apparatus do not match the standard weights, you need to re-set the parameters. Press to move the cursor back to“needle tubing classification”5.3 Testing operationEnter the testing page, the measurement is carried out automatically, the clamping fixture moves downward, when it contacts the artificial skin, the system begins to draw pressure curve. After the fixture is moved the distance 8mm downward, the system will find the Max value of the curve automatically and the fixture goes back to the original position, as well as the operation menu pops out. Figure 5. shows the testing page If something wrong happens during testing, then press ENTER KEY to end the test.After the tested is completed, “Operation tips” pops out, you find the peak value , print curve, check up reports and re-test. Press to move the cursor, Press to carry out the corresponding operation, please read 5.4 for detailed operation about finding peak value, read 5.5 for detailed operation about checking up report5.4 Operation about finding peak value Figure 6 shows finding peak value modethe pressure curve has more than one peaks, when you choose the mode for finding peak value, short press or move the cursor one space to left or right, Long pressor move the cursor to next peak Press to confirm the current peak value. Press to choose print mode or return to back page.5.5 Check up testing reportChoose the “check up report” shown in figure 7., the screen will enter the testing report pagepressor to select ”Print”, “Re-test”, “Delete”, “Return”, if you select “Print” and press , the test report is printed; If you select “Re-test” and press , the next test will be performed; if you select “Delete” and press , the last test results are deleted; if you select “Return” and press , the screen returns to the main menu.5.6 System parameterIf you want to enter “system parameter” in the MainMenu to set the parameters, you need to contact the vendor to get a password. You can not set the system parameters without the password.6. Additional considerations6.1 Operation crew should be familiar with the manual of this apparatus6.2 The instrument should be calibrated every year.6.3 The vendor carries out the“three guarantees” (for repair, replacement or compensation of faulty products) for this apparatus, The quality assurance period is one year long, during this time, if the damages to the apparatuss are not artificial, the supplier is responsible to the maintainance and replacement.6.4 Non-professional staff should no enter “system parameter”6.5 If the users want to verify if the apparatus runs correctly, you can enter “ verify” of 10th item in the Main menu and use the standard weights to verify. If the apparatus can not run properly, the interior system parameters need to be re-set, at this time, please contact the vendor for help.
