The helmet detection instrument is mainly used to detect the performance of the helmet. What should be noted during the use of the helmet detection instrument?
First, ZM-811 helmet impact puncture test machine operation precautions:
1. Before each test, turn on the power switch to allow the instrument to warm up for 10 minutes.
2. After the power is turned on, when the puncture cone touches the head mold, it will emit audible noise. At this time, a safety helmet should be placed on the head mold to isolate it.
3. When the weight or puncture cone is absorbed, the tester should not place the handle or other objects under the weight or puncture cone to avoid danger.
4. For the personal safety of the testers, the protective gloves must be worn throughout the test.
5. It is forbidden to use the ultra-sensor range. It is forbidden to impact the head mold without wearing the headgear.
6, the instrument must have a good grounding!
Second, ZM-815 helmet chin strap strength lateral stiffness tester operation precautions:
1. The instrument is equipped with an electronic ruler and a lower limit warning device. When the rotary lever has a buzzer alarm, stop and reverse the lever to avoid damage to the electronic ruler.
2, the instrument storage must be strictly prohibited fireworks, eliminate fire, should set carbon dioxide and other fire fighting equipment.
3, the operator should have protective clothing, protective gloves, so as not to be hand stabbed.
4, the instrument power supply must have a reliable grounding.
Third, ZM-817 helmet flame retardant tester operation precautions:
1. It is forbidden to use pyrotechnic instruments and gas bottle storage areas to prevent fire, and to extinguish the smoldering samples after the test. Carbon dioxide and other fire fighting equipment should be installed.
2. The gas pipeline must be inspected carefully before starting the machine. Gas leakage is strictly prohibited.
3, the operator should have protective clothing, protective gloves, in order to avoid being stabbed or burned.
4. The exhaust fan should be installed in the workshop to eliminate harmful gases and replace fresh air immediately after the test.
5. After the test is completed, the gas source should be turned off. After the gas in the tube is burned out, turn off the power.
6, gas alarm ringing, please check whether there is leakage.
7. After the alarm of the gas alarm, turn off the power supply and air supply immediately, and then restart the machine after troubleshooting.
8, the instrument must have a good grounding!
Fourth, ZM-818 helmet anti-static performance tester operation precautions:
1, the instrument storage must be strictly prohibited fireworks, eliminate fire, should set the carbon dioxide and other fire fighting equipment.
2. When the hand or human body touches the alligator clip, it is forbidden to start the instrument.
3, after the instrument stops working for 5 seconds, you can remove the thread. If the measured object is more than O.5uF in capacity, for example, in a large motor, a large transformer must manually discharge the ground at both ends of the test to remove the wire and avoid the risk of residual static electricity.
4. After the instrument is used up, please return the measuring line clockwise to the slot and cover the instrument cover.
5. Please remove the battery when it is stored for a long time so as to prevent the battery from leaking and damaging the instrument.
6. When the meter is working, the battery shortage symbol is displayed. Use a Phillips screwdriver to remove the meter back cover and replace the battery with a new one.
V. Operating Precautions for ZM-819 Hard Hat Electrical Insulation Performance Tester:
1. The operator must wear insulating rubber gloves and insulate the rubber pad at the foot to prevent the danger of life caused by high voltage electric shock.
2. The instrument must be reliably grounded and reliably connected to the ground of the subject.
3. When connecting the tested object, it must be ensured that the high voltage output is "0" and in the "reset" state.
4. Do not short-circuit the output ground wire and the AC power cable to avoid high voltage in the housing, which may cause danger.
5, as far as possible to avoid high voltage output and ground short circuit to prevent accidents.
6, test ultra-leakage light once damaged, must be replaced immediately to prevent misjudgment.
7. When the instrument is adjusted to high pressure without load, the leakage current monitoring header has initial current, which is normal and does not affect the test accuracy.
8, the instrument to avoid direct sunlight, do not use and store in a hot, humid and dusty environment.
9. After the instrument is used for one year, it must be sent to the measurement department or the factory after passing the inspection required by the national technical supervision department.
10. It is recommended to use AC regulated power supply.
Sixth, ZM-820 helmet UV pretreatment box handling precautions:
1. During the test, it is strictly prohibited to shake the cabinet, otherwise it is explosive.
2. Do not place the instrument in a wet environment.
3. At any time, it is forbidden to touch the high pressure xenon lamp directly by hand.
4, the operator should have protective clothing, protective gloves, so as not to be hand stabbed or burned.
5, pay attention to when placing the hat, do not touch the high pressure xenon lamp, high pressure xenon lamp is a fragile glass product.
6. During the test, the cabinet should be laid flat so that the xenon lamp is in a vertical state during normal operation, otherwise the life of the xenon lamp will be shortened.
7. Before each time you turn on the Xenon lamp, you should check whether the cooling fan is working normally (wind blow out from the outlet of the Xenon lamp). It is forbidden to turn on the Xenon lamp when the cooling fan is not working (for example, it is broken)!
8, the instrument must have a good grounding!
VII. Precautions for high temperature pretreatment of ZM-821 hard hat:
1. Regularly wipe the residual solution in the test chamber.
2. The power supply for this instrument is single-phase AC power and must have a reliable grounding wire.
Eight, ZM-822 hard hat low temperature water immersing pretreatment box operation precautions:
1. When setting the temperature above 0°C, it is forbidden to turn on the heating switch without adding water.
2, the instrument storage must be strictly prohibited fireworks, eliminate fire, should set carbon dioxide and other fire fighting equipment.
3, the operator should have protective clothing, protective gloves, so as to avoid frostbite.
4. Regularly wipe the residue in the test chamber.
5. After the water immersion test is completed, the water should be drained in time.
6, the instrument must have a good grounding!
