3 the structure and working principle
The working principle of 3.1ZHZ8ED-5 type power frequency withstand voltage tester
Withstanding voltage tester is composed of high voltage boost circuit (test voltage to adjust the output energy required), leakage current detection circuit (set alarm current) and value indicating instrument (direct readout output voltage and leakage current value or breakdown alarm current value). In the test, the measured at the time stipulated in the provisions of the testing voltage, automatically cut off the output voltage instrument; once the breakdown, i.e. the leakage current exceeds the set alarm current will alarm.

4ZHZ8ED-5 type frequency withstand voltage tester safety precautions
4.1 before using please read the instructions and follow the instructions step in operation.
4.2 do not use non original accessories, in order to avoid danger.
4.3 instruments and the measured object must be well grounded, not allowed to tie in the tap water pipe.
4.4 the instrument to generate sufficient pressure caused casualties. In order to prevent electric shock accidents, before using this equipment, please wear insulating rubber gloves, foot pad insulation rubber pad, and then the relevant operation.
4.5 when the instrument is in the test mode, please do not touch the test line, the analyte and the output terminal.
4.6 do not make the short circuit test line of the instrument and the AC power line, lest the whole instrument charged.
4.7 when testing a sample, to replace another object to be measured, should make the tester in the testing indicator lights and high lights out and showing the value of voltage" Zero "Qualified indicator lights or alarm indicator light, and then replaced. Special note: during the test, please do not touch the high-voltage testing head, so as to avoid accidents.
4.8 when the power switch is switched off, such as open again, you need to wait a few seconds later, the "zero" indicator light, don't move the power switch for opening and closing, in order to avoid the wrong actions damage the instrument.
4.9 instrument no-load test, leakage current will have value.
Because of the low end instrument current sampling circuit in high voltage circuit (near ground loop). When the voltage to high voltage, the leakage current of high voltage transformer itself through the core into the current detecting circuit, caused by no-load leakage current has little value. This is a normal phenomenon, does not affect the test accuracy.
In the following 4.10 to avoid the use of the environment:
Avoid placing the sun a.. The rain or damp place.
B. please away from fire and heat, to prevent the high temperature of the machine.
C. handling or maintenance, should be shut down and will remove the power line.
5 use and operation
5.1 preparation
5.1.1 close the drawer on the right side of the air switch, the power supply is switched on, the power switch is in the "on" position. At this time, display output voltage, leakage current and time of the digital tube and the "test unit" indicator Ying Liang. "Return to zero" indicator, the value is zero, the last time that the set value, the instrument is in the initial state. Such as the boot "back to zero" indicator light does not shine, according to the "emergency stop" button, the instrument regulator automatic return to zero.
5.2 set operation
5.2.1 testing time
First click on the "reset" button, then click "Settings" button, the test voltage display window display" T-- " , Time display window to display a set time value, the left (decrease) or right (increase) rotation "set" button, to get the test time needed, press "set" button again, save the test time, at the same time to enter the current alarm value setting.
The current alarm set value 5.2.2
When the test time is saved at the same time, the test voltage display window display" A-- " , Leakage current alarm window displays the current setting a value through the left or right (decrease) (increase) rotation "set" button, to get the current alarm required, press the "set" button again, save alarm current value, at the same time to enter the boost voltage value setting.
5.2.3 boost voltage setting
When the alarm current value is stored at the same time, the test voltage display window display" U-- " , The leakage current window shows a boost voltage setting value, the left (decrease) or right (increase) rotation "set" button, to get the boost voltage required, press the "set" button again, that holds the boost voltage value, at the same time to zero does not return to zero setting.
5.2.4 is not set to zero to zero
When the boost voltage value is saved at the same time, the test voltage display window display" Go-0 " , Leakage current window display" On "Or" OFF "The left or right rotation" set "button to get" On "(return to zero) or" OFF "(not zero), press the" set "button again, which hold the desired set state, at the same time to enter the test set of three phase to ground and test.
5.2.5 three relative to the test phase to ground and test set
When not to return back to zero zero setting is saved at the same time, the test voltage display window display" S-C " , Leakage current window display" S "Or" C "The left or right rotation" set "button to get" S "(three phase to ground test state, i.e. UVW - G ) or" C "(the state of phase to ground and test), press the" Settings "button again, which hold the desired set state, and return to the initial state measurement.
5.3 steps
5.3.1 in determining the output voltage value for instrument" Zero "The test indicator goes out, high light goes to zero and light condition, the output high voltage line" U "," V "," W "Connected to the power input end of the measured object, then the low end" Zero "Receiving the measured object on the shell.
5.3.2 press the "start" button, the "test" indicator light, the test voltage rises slowly, the voltage value is the current value of the test voltage, when the voltage rises to a preset value, the start time. The leakage current value as measured on the current leakage current value, as measured by the breakdown, or leakage current exceeds the alarm current setting value. The alarm lights, buzzer alarm, automatically cut off the output voltage instrument, and automatically return to zero. The "zero" indicator light, automatically eliminate the alarm. When the test voltage required rise test voltage to the user, such as the analyte in the test time of the leakage current is less than a preset alarm current, is the instrument in the test time, automatically cut off the high voltage discharge indicator light, then the "qualified" indicator light; if set to work voltage and phase. Qualified back to zero, then the operating steps of it as follows: click the "start" button," UVW - G "Light. High pressure indicator, automatic booster, rise to the voltage set after the beginning of time, time to buck, back to zero, back to zero, zero indicator lights, and high voltage indication lamp," UVW - G "The light is off;" UV - WG "Light, high light, zero indication lamp, boost up to the set voltage value, start time, time to buck back to zero, back to zero, zero indicator lights, and high voltage indication lamp," UV - WG "The light is off;" U - VWG "Light, high light, back to zero indicating lamp. Boost up to set voltage value, start time, time to buck back to zero, back to zero, zero indicator lights, and high voltage indication lamp," U - VWG "The light is off, the discharge lamp, automatic discharge, qualified indicator lights. The end of the test, the replacement of a load.
Note: One Whether or not choose to return to zero zero operation, once the alarm, automatically cut off the pressure regulator automatically return to zero pressure.
5.3.3 should ensure the instrument in the discharge, can replace the analyte or the next test.
5.3.4 manual operation: the "automatic" switch button, the instrument is in manual mode, and then press the start button, press the "voltage rise" button, when the voltage rises to the voltage setting start time, other methods of operation.
If the 5.3.5 in the process of testing, safety problems, please press the emergency stop button, the end of the test.
