data transmission between the host and the anti-shock ammeter. B. High voltage unit: 1. The quick-installed aviation socket with aluminum base is used to connect with the control box. When installing the cable, first lay the high-voltage generator flat on the ground, align it with the plug positioning pin, press down and screw it clockwise, and do not shake it from side to side.

(Built-in antenna model) low-voltage level configuration, available when long-distance or outdoor tests are not required. 1. LCD display: current value display, unit display, polarity display, battery power display. Among them, the power indicator only has full power and no power status. The battery can be replaced when it shows no power.

the internal discharge resistance adopts the specification of 2M Ω /25W. The ground wire discharges directly, and at the initial discharge, the discharge rod approaches the high-voltage measurement end of the discharge test object from far to near. First enter the arc discharge through the air.
(1) During the test, the human body must not touch the cable to prevent electric shock. (2) Try to avoid cable dragging, strong twisting, water immersion and large tensile force. (3) When the DC voltage is greater than 60kV, the composite insulation is used to improve the pressure bearing capacity.

Maximum voltage : the maximum voltage that the instrument can output, actually up to 1.1 times the rated voltage. Cannot be changed. Maximum current : the maximum current that the instrument can output. Cannot be changed. Protection voltage : higher than the test voltage setting, it can ensure that the maximum voltage does not exceed the voltage value of the test product.

The top of the interface displays the set overvoltage protection, test voltage, timing length and other parameter values. All start and stop buttons take effect after long pressing for 1 second, and other buttons are triggered by jogging, which is applicable to all interfaces. The boost and buck buttons are equivalent to the output adjustment mechanical knob in the lower right corner of the instrument panel, both of which can control the voltage output.

again. If it is a capacitive test object, artificial discharge must be carried out. ② MOA test interface--- The automatic test function of zinc oxide arrester is as follows Note: When performing the automatic test of the zinc oxide arrester, the test voltage setting should be 10% higher than the voltage at 1mA, and the overvoltage protection value should be at least 2KV higher than the test voltage.

On the right is the result of each step of the test. ④ Automatic test interface During the automatic test, the right side records the record of 1-10 minutes. 4. Introduction to the principle of capacitive test method...

When conducting capacitive test products such as cables, the equivalent circuit is an RC circuit, so there is a problem of attenuation and oscillation; reflected in the voltage, the voltage will fluctuate up and down until it stabilizes. This stabilization process is related to the equivalent capacitance of the test product.
considered as 1 mA when the current is 950 uA to 1050 uA , and the voltage change at this time is about 0.02kV, which fully meets the requirements of the "Zinc Oxide Surge Arrester Test Standard" GB11032-89 . According to the voltage level of the tested product, the equipment corresponding to the voltage level is selected to make the test operation faster and more accurate.

1. Data query 【Print】: Print the current record data, including the test date and time at that time. 【Export】: Export all the data to the U disk, use a random configured U disk, or a U disk with a format of FAT32 and a capacity of less than 32G. Insert the U disk and then select this menu to execute.
3. The head is paired to configure the host and anti-shock current This function has been correctly configured one-to-one before leaving the factory, and only needs to be configured after replacing the anti-shock ammeter. Follow the setting steps to operate. VIII.

1、 In order to ensure personal safety and equipment safety, the instrument should be well grounded and fully discharged after testing. 2、 The ground connection between the control box and the high voltage generator must be firm and reliable, and the ground screw at the bottom of the high voltage generator must be connected to the ground.
9、 The concave interface of the high-voltage equalizing cover has strong magnetism. When the high-end ammeter is connected to it, it should be approached slowly to avoid collision. 10、 In the capacitive sample test, due to the existence of RC charging oscillation and polarization absorption current phenomena, the voltage will enter a steady state after 1 minute.
