At this time, the word\"\" MEM\"\" will flash-the number of saves will be displayed first, and the saved data will be automatically displayed after 2 seconds. Press the\"Zero Set\" key to return to the measurement interface.

4.9 \"Zeroing \" key

When you press this key, the test value on the screen will be reset to zero. Note: When the instrument is reset to zero, the instrument can only be reset to zero in the real-time measurement mode and under the peak and automatic peak.

※ Select a lighter fixture or release the applied load and clear it again.

※ On the \"View \" interface, press and hold this key for 4 seconds, all the stored test data can be cleared (it may not be cleared in some states, then restart the machine and then execute this function to clear all saved data) .

Five, screen display instructions

5.1 PEAK

When \"PEAK \" is displayed, it means Peak mode, and the display shows the peak value until it is manually cleared. When \"AUTO PEAK \" is displayed, it means \"auto peak \" (Peak hold automatic release mode) ), It will be cleared automatically after 2 seconds of displaying the peak value; when \"PEAK \" is not displayed, it means \"track mode \" (real-time load value mode).

5.2 MEM

Ten, test operation steps

1. The specific operation method of the instrument installed on the test machine:

A. Unscrew the adjustment handle 1 first, and slide it down to make contact with the chassis 2 so that the two mounting holes above the mounting plate 3 are exposed; then use the mounting screws and spring pads to install the two upper holes of the instrument on the mounting plate 3. ; Finally, loosen the adjustment handle 1 and return to the original upper position to lock it. (As pictured above)

B. After the handle 4 is pressed down, the two mounting holes below the mounting plate 3 can be exposed; then the two holes below the instrument are mounted on the mounting plate 3 with mounting screws and spring pads. (As shown in Figure 2 above)

C. Follow the two steps above to tighten all four screws.

2. Select a suitable probe (Note: when a probe with a diameter of 11 is used, the hardness value displayed by the instrument is the actual fruit hardness value; when a probe with a diameter of 8 is used, the hardness value displayed by the instrument is 2 times the actual fruit hardness Value), use a connecting sleeve with an internal thread to mount the probe to the test rod of the instrument. (As pictured above)

3. Before measurement: First peel the fruit to be measured about 1 square centimeter of peel. When measuring, make the center of the fruit to be tested line up with the test rod of the instrument so that the force value of the test can be more accurate. (As pictured above)

4. Start the measurement: press the\"On\" button to turn on the power. After the LCD display is stable, press the\"Peak\" button to enter the peak measurement mode. (If the display is not zero, press the\"Zero\" button. (Cleared), press the handle 4 down to make the probe point to the peeled flesh, press it evenly until the score line, and complete the measurement. The displayed value is the fruit hardness. (Figure 4)

5. After the test is completed, remove the load, turn off the power, remove the jig, clean each item and put it back in the tool box for the next use.

Eleven safety precautions

1. Matters needing attention:

a. After purchasing this instrument, if the instrument has insufficient power, it needs to be charged for 4 ~ 6 hours before it can be used normally.

b. To purchase this instrument, you must use the RS232 computer cable included in the accessories distributed by our company.

c. If the operation is incorrect, it may damage the instrument or cause serious accidents. This manual points out important matters for preventing accidents and how to use the instrument. Please read this manual carefully before use, and keep it in a safe place for future reading.

d. If it is testing the impact load, please choose the model with the maximum load double the impact load to be tested.

2. Warnings:

a. During the destructive test, wear a protective mask and gloves to prevent the splashing material from hurting the human body during the test.

b. Do not use fixtures that are damaged or severely deformed. Please refer to the relevant parameters in this manual for the self-made jig (the company has other kinds of jigs, customers can choose according to their needs; purchase separately).

C. Do not use the instrument beyond its maximum range. Doing so may cause damage to the sensor or even an accident.

d. When the test value exceeds 100% of the full scale, the buzzer will beep continuously. At this time, please quickly remove the added load or reduce the load. When the test value exceeds 120% of the full scale, the instrument may be damaged.

3. Solve the crash state: When the instrument crashes unexpectedly, press a small round rod on the left side of the instrument and press a button labeled\"\" Reset\"\" to quickly reset and shut down.

4. Safety matters:

a. Please use the matching charger to charge, otherwise it will cause circuit failure or even fire.

b. Do not use a power source other than the rated voltage of the charger, otherwise it may cause electric shock or fire.

c. Do not pull out or plug in the power supply with wet hands, otherwise it may cause electric shock.

d. Do not pull the power cord of the charger to pull out the plug, so as to avoid the electric wire being torn and getting an electric shock.

e. Please use a soft cloth to clean the machine. Immerse the cloth in water soaked in detergent and wring it dry before removing dust and dirt. Note: Do not use volatile chemicals to clean the unit (such as volatile agents, thinners, alcohol, etc.).

f. Do not operate the machine in the following environments

① A humid environment ② A dusty environment ③ A place where oil or chemicals are used ④ A place with a vibration source around

g. Please use and store within the specified temperature and humidity range, otherwise it may cause the instrument to malfunction.

h. Do not disassemble, repair or modify the machine yourself. These actions may cause permanent failure of the instrument.
