(Note: Sometimes after turning on the power, there may be a zero-drift value display of the analog signal on the screen, that is, the value display drifts up and down at zero point. Clear the “clear” button to clear it;

2 , "Shutdown" button:

Press this button to turn off the power. (Note: Whenever you press this button, the power is turned off, but the stored memory data will not disappear);

3 , "memory" button:

When this button is pressed, the stored test data (memory data) will be recalled and displayed on the screen in turn. At this time, the word “MEM” flashes first to display the number of memories, and after 2 seconds, the memory data is automatically displayed. If you want to exit the memory function interface, just press the “clear” button to exit;

4 , "Unit" button:

Press this button to switch the measurement unit. Provide N (Newton), Kg (kg), and lb (lb). Each time you press this button, the unit will switch to the next unit.

5 , "peak" button:

Press this button to switch between manual peak hold, automatic peak hold, and load real-time value. “PEAK” displayed on the LCD indicates manual peak hold, “AUTO PEAK” indicates automatic peak hold, no “PEAK”. "and "AUTO PEAK" display shows the real-time value of the load. Each time the button is pressed, the mode switches to the next mode;

6 , "storage" button:

When this button is pressed, the test data displayed on the screen is stored (in the manual peak state). The stored data can be called up by the “memory” button, cleared by the “clear” button, or output to the computer for analysis or printing. When there is test data stored in the machine, there will be a “MEM” display on the LCD.

7 , "clear" button:

When you press this button, the test value on the screen will be reset to zero.

※ When the weight of the clamp used exceeds 20% of the range, press the “clear” button to clear it. In this case, you need to select the lighter fixture first, and then press the “clear” button to clear it.

※ When the load used exceeds 20% of the range of the machine, press the “clear” button to clear it. In this case, the load must be released first, and then press the “clear” button to clear it.

※ Press and hold this button for 4 seconds, the stored test data can be completely cleared (Note: In some states, it may not be cleared, you need to turn off the power first, turn it off and then turn it back on, then press this function key to clear all memory data. );

8 , "communication" button:

Press this button to switch the screen number positive and reverse.

Five, the screen display instructions

1 , PEAK

When “PEAK” is displayed, it indicates Peak mode, the display shows peak value until manual clear; when “AUTO PEAK” is displayed, it means “auto peak” (peak is automatically released mode), and the peak value is displayed for 2 seconds. After the automatic clear; when "PEAK" is not displayed, it means "track mode", the value on the screen changes with the load;

2 , LO BAT

When the battery voltage drops below 7.0V, “LO BAT” appears on the screen, indicating that the voltage is insufficient and needs to be recharged (it can still be tested while charging);

3 , MEM

When there is data stored in memory, “MEM” will be displayed. When the “DATA” button is pressed to view the memory data, “MEM” flashes.

6. Storage (memory) information:

X. Test procedure

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

A. Loosen the adjustment handle 1 first, and slide it down to contact the chassis 2 to expose the two mounting holes above the mounting plate 3. Then install the upper two holes of the instrument on the mounting plate 3 with mounting screws and spring washers. Finally, loosen the adjustment handle 1, and return it to the original upper position to lock it. (Figure 1 above)

B. After the handle 4 is pressed, the two mounting holes below the mounting plate 3 can be exposed; and the lower holes of the instrument are mounted on the mounting plate 3 by using mounting screws and spring pads. (Figure 2 above)

C. Follow the previous two steps to tighten the four screws.

2, select the appropriate probe (Note: the selection of the diameter of the probe 11, the instrument displays the hardness value hardness actual fruit; the selection of a diameter of the measuring head 8, the display device is two times the actual hardness value hardness of fruit Value ) , attach the probe to the test pole of the instrument with a connecting sleeve with internal thread. (Figure 3 above)

3. Before the measurement: Firstly, the fruit to be tested is peeled off by about 1 square centimeter. When measuring, the center of the fruit to be tested is in line with the test rod of the instrument, so that the force value of the test can be more accurate. (Figure 3 above)

4. Start measurement: press “Power On” to turn on the power. After the LCD display is stable, press “Peak” to enter the peak measurement mode (if the display is not zero, press “Zero” to clear), the handle will be 4 Press down to make the measuring head face the peeled pulp, evenly press it into the line, and complete the measurement. The displayed value is the hardness of the fruit. (Figure 4)

5. After the test is completed, remove the load, turn off the power, remove the fixture, and clean the objects and put them back into the tool box for the next use.
