Tracking the change of the test load value in any state shows that when the test load value disappears, it returns to zero. At this time, the PEAK function does not work.
0001 Standard test mode (factory default mode)
Three modes can be set in this mode, namely the real-time load status, peak hold status and automatic peak status. When \"PEAK \" is not displayed on the display, it is the state of the real-time load, and the test value changes with the change of the load. When the\"Peak\" key is displayed, the word\"PEAK \" is displayed. The displayed test value is the maximum value in the test (regardless of the tension and pressure), which needs to be manually cleared; press the\"\" Peak\"\" key again, and the\"AUTO PEAK\" display will show the automatic peak status. The displayed test The value is the maximum value in the test (regardless of tension and pressure), and it will automatically disappear and return to zero after holding the display for 2 seconds.
0002 Push-pull peak mode-the function of simultaneously grasping the maximum load value in both pressure and tension directions. During the connector test, it grasps the function of the maximum load (Fc.Ft) of the positive and negative sides of the insertion force and the extraction force.
※ When the load applied by both the positive and negative sides is greater than the induced value Fa and the load is lower than the induced value Fa, the test is counted once (one cycle) and the test is completed (end). Be sure to set the sensing value Fa (sensing range).
0003 Pull force peak mode-When plugging and unplugging test, only grasp the function of the maximum load (Ft) of pulling force.
0004 Pressure peak mode-During the plug-in test, only the function of the maximum load (Fc) of the plug-in pressure is grasped.
0005 0006 Switch contact on-off force test mode-accurately measure the load value at the moment of contact on-off.
0005 Maximum force value of the external node from the moment of opening to the moment of opening
Connect the two contacts under test to pins 4 and 5 of the data interface (using the data plug in the accessory), press the\"Peak\" key to select the peak mode, and apply pressure to the switch by pushing and pulling the force gauge until The switch is on. The measured force value is the force value required to switch on the switch.
0006 The maximum value of the external node from the moment of being connected to the moment of being disconnected
Connect the two contacts under test to pins 4 and 5 of the data interface (using the data plug in the accessory), press the\"Peak\" key to select the peak mode, and apply pressure to the switch by pushing and pulling the force gauge until The switch is turned off, and the measured force value is the force value required to open the switch.
Test the operating load of switches, buttons, etc. as shown below:
Set in \"PEAK \" state, Fp is the test data value.
After the applied load is greater than the set value of Fa, the load value of the display will stop changing until the contact changes from off to on or from on to off. The displayed value is the test value.
※ Please connect PIN4 and PIN5 of the data interface as the contact signal (use the data plug in the accessory).
※ The test cannot be performed without setting Fa (sensing range).
AODT sensor setting
When pushing and pulling at the same time, set the sensing value Fa. For example: thrust test, if the value exceeds the induction value, it means \"push \" to start the test. After that, the value is lower than the induction value, which indicates that the thrust test is over. On the contrary, the reverse direction tensile test can be performed. Pull\"\" to start the test, after which the value is lower than the induction value, indicating that the pull test is over.
LODT test value lower limit setting
Set the lower limit of the test value. If it is lower than the lower limit, it is out of range. \"MIN \" is displayed.
HIDT test value upper limit setting
Set the upper limit of the test value. Above the upper limit is out of range, \"MAX \" is displayed.
CPDT comparison value setting
