Specification Brand : Dntum BulletPoint : 【 Durable HDPE Material 】 Our gravel grid made of high dense polyethylene material, it has super chemical stability and high toughness. Eco-friendly, wear resistant, heat resistance, cold resistance, excellent resistance to all common elements in the soil.【 Foldable & Scalable 】 Flexible in expansion and contraction, you can be folde BulletPoint1 : The products are distributed with voltmeters, ammeters, tuning knobs, power switches and point switches. BulletPoint2 : When the power switch is turned on, the voltmeter indication should be around 6 volts. If the voltage is low, the discharge distance will be shortened accordingly. Rotate the tuning knob to tune the pressure between the two discharge balls as needed. BulletPoint3 : The function of the point switch is to make the electric motor produce instantaneous discharge, such as used in the gas explosion experiment; when the power switch is turned on, the electric motor can discharge for a long time. BulletPoint4 : The motor is connected to a 6V/0.5A stabilized power supply. If it does not work, check whether the DC output plug has been inserted into the power socket of the electronic motor and whether the stabilized power supply is well connected to the ~220V power socket. BulletPoint5 : Operation method: Open the discharge bracket cover, a folded discharge bracket, and adjust the discharge rod upright. Adjust the distance between the two discharges to about 30mm. Turn on the power switch of the electric motor. Just as the two discharge balls are in a stable discharge state, the electric discharge is proved. When the motor is running normally, turn off the power supply and short-circuit the two discharge balls, discharge the residual charge on the discharge rod, and prepare for Color : One Color ExternallyAssignedProductIdentifier : 7071545136038 ItemName : Electrostatic Generator High-Voltage Static Electricity generating Device high School Physics Teaching Equipment ItemPackageDimensions_Height : 22 centimeters ItemPackageDimensions_Length : 32 centimeters ItemPackageDimensions_Width : 22 centimeters ItemTypeKeyword : industrial-and-scientific-esd-supplies Manufacturer : Dntum MetalType : other ModelName : Pongnaswe0tgbs3o9-11 ModelNumber : Pongnaswe0tgbs3o9-11 PartNumber : SYMXZJ00723 ProductDescription : Product Name: Electronic Lifting Motor Product size: 19*16*9cm Product weight: 1.5kg Precautions: 1. The product is a high-voltage static electricity generating device. When the power is turned on, all exposed metal parts on the discharge rod are charged with high-voltage static electricity. Be careful not to get close or touch your hands or body to avoid electric shock, especially to avoid two hands approaching at the same time. Two electrodes, this will cause a heavy electric shock. If you need to connect high voltage to the experimental device during the experiment, you should turn off the power supply and disconnect the remaining power before connecting to avoid electric shock. After the experiment, turn off the power supply, short-circuit the two discharge balls, discharge the remaining electricity, return the bracket to its position, and cover the protective cover. 2 Please do not open the box to avoid damage to high-voltage components. 3. When experimenting, please pay attention to safety and carry out the experiment according to the steps.
