Fourth, the button description

4.1 \"Startup \" key:

When you press this key, the power is turned on and the model number is displayed. After powering on, before pressing the\"\" Zero\"key\" to clear, the zero drift value of the analog signal may be displayed on the screen, just press the\"\" Zero\"key\" to clear it.

4.2 \"Shutdown \" key:

In the power-on state, when you press this key, the power is turned off, but the stored saved data will not disappear. When starting up (that is, when the model number is displayed and the measurement interface 0.0 is not displayed), pressing the shutdown key at this time cannot respond.

4.3 \"Save \" key:

In the peak measurement interface state, press this key to save the test data displayed on the screen; in the function setting interface state, press this key to save the set parameters. When some test data is stored in the machine, \"MEM \" is displayed. This machine can store 447 data.

4.4 \"Peak \" key:

Each time you press this key, there will be a switch between \"PEAK \" display, \"AUTO PEAK \" display or \"PEAK \" disappearing—that is, peak hold, peak hold automatic release, and load real-time value mode switching.

4.5 \"Unit \" key:

Press this key to execute the measurement unit switch, which can display three units of N (Newton), kg (kg) and lb (pound) in a cycle. When the test data is displayed, the unit conversion of the same value can also be completed.

4.6 \"Settings \" key:

In the real-time measurement interface, press this key to enter the setting item interface; in the setting item interface, press this key to enter the required setting option.

4.7 \"Rotate \" key:

This key is only valid in the test interface. When this key is pressed, the measured value displayed on the screen will flip 180 degrees.

4.8 \"View \" key:

When you press this key, the stored test data will be called up and displayed on the screen in sequence. 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 this key is pressed in the measurement interface, the test value on the screen will be reset to zero.

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

※ In the view of stored data interface, press and hold this key for 4 seconds, all stored test data can be cleared (it may not be cleared in some states, restart the machine after powering off and then execute this function to clear all the 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) ), The default display peak value is automatically cleared after 5 seconds; when \"PEAK \" is not displayed, it means \"track mode \" (real-time load value mode), and the value on the screen changes with the change of load;

5.2 MEM

When data is stored,\"MEM\" is displayed; when you press the\"View\" key to view the stored data,\"MEM\" flashes.

Six, stored data

6.1 Stored data

In the PEAK state, after the test is completed, press the\"Save\" key to store the data. The display will show\"MEM\" on the display. The stored data can be saved even after the power is turned off. When you use the\"\" View\"\" key to view the stored data,\"\" MEM \"flashes, the number of times of storage appears first, and the stored value automatically appears after 1 second. Press the\"Zero Zero\" key to return directly to the measurement interface. The data can also be input into a computer for analysis and processing. This machine can store 447 data.

6.2 Clearing stored data

When pressing the\"\" View\"\" key to enter the stored data interface, press the\"\" Zero\"\" key for more than four seconds, all the stored data will be cleared,

\"MEM \" disappears.

This machine can be connected to a computer and enter test data into the computer. View and print the number of tests, average, maximum, minimum, and determine whether the test results meet the set requirements.

7. Other functions:

Safety Precautions

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

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

3. Do not pull out or insert the plug with wet hands, otherwise it may cause electric shock.

4. 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.

5. 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.

6. Do not operate the machine in the following environments

(1) Humid environment (2) Dusty environment

(3) Where oil or chemicals are used (4) Where there are earthquake sources around

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

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

9. Other outstanding matters needing attention in safety production.
