4. Model specifications

Five, screen display

①, three kinds of display: after booting, when there is no character display, it means \"track mode \" (real-time load measurement mode), the value on the screen changes with the change of load; press \"peak \" key here When \"PEAK \" is displayed, it indicates Peak mode (peak hold measurement mode), and the display shows the peak value until it is manually cleared; press \"Peak \" key here, when \"AUTO PEAK \" is displayed, it means \"autopeak \" (Peak hold automatic release measurement mode), automatically save and clear the peak value after displaying the peak value for 10 seconds, the peak time of 10 seconds can be freely set. For details, please refer to the(PE.SET) Explanation}.

② With or without data storage display: when there is no \"MEM \" displayed, it means that no data is saved in the instrument; when there is \"MEM \" displayed, it means that there is data saved in the instrument; When you press \"View \" on the measurement interface to view the saved data, \"MEM \" is flashing.

③ Push and pull instructions: In this machine, the thrust (pressure) is displayed as a negative value (\"-\"), and the pulling force is a positive value (\"+ \" is not displayed).

④ Comparison function. When setting the comparison value via STOP (for details, please refer to the(STOP) Machine stop value description), this function is activated. \"CMP \" is displayed. It can be set separately according to need when using.

⑤, measurement force value display.

⑥ Display of upper and lower limit values ​​reached: When \"MIN \" is displayed here, it indicates that the measured data reaches and is below the lower limit; when \"MAX \" is displayed here, it indicates that the measured data reaches and The upper limit is exceeded.

⑦, three units display: N (cow), kg (kilogram), lb (pound) three units are displayed separately, converted by pressing the unit key. When HF10K and above specifications, K N (kilo-newton), K Kg (ton), \"K lb (kilo-pound) \" are displayed here.

⑧, power display: when the battery voltage drops below 7.0V, it indicates that the voltage is insufficient and needs to be recharged (it can still be tested during charging). There is a power indicator light above the power button. When the charger is plugged in for charging, the indicator first changes from red to green. This process is repeated twice, indicating that the charging is normal, then the indicator light is red, and the indicator light changes when fully charged Into green. If the instrument is not used for a long time, and the battery power is too low, the indicator light may not light up when the charger is plugged in. After about half an hour, after the battery is woken up, the indicator light will turn red and the charging time will be 4 ~ 6 hours.

8. \"View \" key

When you press this key, the stored test data will be recalled and displayed on the screen. At this time, the word\"\" MEM \"flashes-the number of saves is displayed first, and the saved data is automatically displayed after 2 seconds. Press \"Zero \" to return to the measurement interface.

9. \"Zero \" key

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

※ Choose a lighter fixture or remove the added load and clear it again.

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

Seven, boot display

Eight, function introduction

1. Setting function

a. Mode switching: After the boot is complete, press \"Settings \" key, \"TEST \" appears, press \"Settings\" key again, 0001 mode appears, use\"Keys can choose different modes. As shown in the figure below:

0001 Standard test mode (factory default mode): In this mode, three states can be set, namely real-time load state, peak hold state and automatic peak state. When there is no \"PEAK \" on the display, it is the real-time value state of the load, and the test value changes with the change of the load; press \"Peak \" key, when the word \"PEAK \" is displayed, it is the peak hold state The displayed test value is the MAX value of the test (regardless of tension and pressure), which needs to be cleared manually; press \"Peak \" key again, \"AUTO PEAK \" display, it is the automatic peak state, the displayed test The value is the MAX value in the test (regardless of tension and pressure), and it will automatically disappear after returning to zero for 2 seconds, and the next test can be performed.

0002 Push-pull peak mode: the function of simultaneously grasping the MAX load value in both directions of pressure and tension. When testing the connector, grasp the function of the MAX load on both the positive and negative sides of the insertion force and the extraction force.

0003 Peak thrust mode-only the MAX load function of insertion pressure is grabbed during the plug-in test

0004 Tension peak mode-when plugging and unplugging, only the function of MAX load that pulls out the tension is captured.

0005 0006 Switch contact on-off force test mode-accurately measure the load value at the moment of contact on and off action.

0005 The maximum force value of the external node from the moment of disconnection to the moment of connection. Connect the two tested contacts to pins 4 and 5 of the data interface, press \"Peak \" to select the peak mode, and apply pressure to the switch through the push-pull force gauge until the switch is turned on. The measured force value at this time is the force value required to turn on the switch.

0006 The MAX value of the external node from on to off. Connect the two tested contacts to pins 4 and 5 of the data interface (using the data plug in the accessory), press the\"\" peak\"key, select the peak mode, and apply pressure to the switch through the push-pull force gauge until When the switch is open, the measured force value at this time is the force value required to open the switch.
