ZF-618 seatbelt tension testing machine is an important equipment for seat belt inspection. It is widely used in seatbelt manufacturing companies and construction engineering quality inspection units. Seatbelt tension testing machine is an important testing equipment for the inspection of seatbelts. It must be used strictly. Use according to operating specifications and strictly observe operating instructions.
First, the operation 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
System default oyt unit is second
3. Adjust the position of the loading device by “raising the jog†and “dropping the 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 automatically unload. Press 
†The key is 2 seconds, the electrical machinery stops. Remove the sample, observe and record the state of the sample.
End of the trial, press " 
"The key can be switched to show the peak value.
5. Repeat the above steps to test the next sample.
Second, the use of matters needing attention
1. The meter on the instrument has two display windows. The first window displays the sensor force value in units of N; the second window displays the countdown time and the unit is 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, change 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 will be 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 10 seconds. To stop the test midway, use the “Clear†key.
