First, the operating instructions 1, according to the type of test sample, select the appropriate speed (100mm/min or 20mm/min).
2. Turn on the power switch and set the load value (out1) and load holding time (oyt) to be loaded on the control instrument. The specific operation steps are as follows:
Press and hold the “SET†key to enter the parameter settings, press the “MOD†key to convert each parameter, press the “<†key to enter the parameter, and use the “<â€, “∧†and “∨†keys to change the parameter setting value, force value parameter For AV, the time parameter is OYT; after setting, press “MOD†key to save, then hold “SET†key until return to the test state.
System default out1 unit is N
The default oyt unit of the system is 3 seconds. The position of the loading device is adjusted by “rising jog†and “dropping jog†so that the test sample can be smoothly installed, and the required test sample can be installed in place according to the standard requirements.
4, press the "Start" button, the motor starts to pull the chuck to load the sample, while the instrument is automatically cleared. When the loaded load value reaches the set value out1, the instrument automatically starts the countdown clock and is displayed in the second window of the instrument.
When the countdown time reaches 0, the motor drives the chuck to be automatically unloaded. Press the "" key for 2 seconds and the motor stops. Remove the sample, observe and record the sample status.
At the end of the test, press the "" key to switch the display peak.
5. Repeat the above steps to test the next sample.
Second, the use of Note 1, the instrument on the instrument has two display windows, the first window shows the sensor force value, the unit is N; the second window shows the countdown time, in seconds.
2. Before the test, please warm up for 15 minutes.
3, when the instrument is running, please do not put the head, hands, etc. close to the chuck and moving parts to avoid injury.
4, non-professional maintenance personnel shall not open the cover to disassemble, modify the internal electrical devices.
5. In case of emergency, please quickly press the emergency stop button and cut off the total power. Remove the fault and turn it on again.
6, the instrument power supply for single-phase AC power, must have a reliable grounding line.
7. The dynamic test part of the instrument is provided with upper (lower) limit stroke protection. When the loading device is operated to the upper (lower) limit position, it is protected. At this time, it is necessary to press “reset†(“startâ€) or "Drop In" ("Drop In") lowers (raises) the loading device a distance.
8. The "Reset" button on the operation panel can only be used after the end of a test, ie, the indicator light flashes, and the beep is 10s. To stop the test midway, use the "Clear" key.
