Operating Regulations Of Withstand Voltage Tester
1 Intent
In Order To Ensure The Normal Use Of Testing Equipment And The Safety Of Users, As Well As Whether The Tested Product Meets The Specified Requirements, This Operating Specification Is Formulated.
2 Scale
The Withstand Voltage Tester Used By Our Company.
3 Application Method:
1. Plug In The 220V, 50Hz Power Supply, Connect The High-Voltage Output Line And Output Low-End Line To The High And Low Output Terminals Of The Instrument Respectively, And Place The Ends Of The Two Output Lines In The Air;
2. Set The Breakdown Current According To The Experimental Requirements: Press The “Power Switch” → Press The “Alarm Current Setting” Button, And Turn The Current Adjustment Knob To Make The Current Display Value The Required Alarm Value For The Experiment. After Setting, Release The “Alarm Current Setting” Set Button;
3. Set The Experimental Time According To The Experimental Requirements: Press The “Punctual/Continuous” Switch To The “Punctual” Position, Dial The Number On The Dial Code To Adjust The Time Value Required For The Experiment; When The Setting Is Over, Release The “Punctual/Continuous” Switch To The “Continuous” File;
4. Set The Experimental Voltage According To The Experimental Requirements: First Turn The Regulator Knob Counterclockwise To The Zero Position, Press The “Start” Button, The “High Voltage” Indicator Light Is On, Turn The Regulator Knob Clockwise Until The High Voltage Appears And The Appearance Indicates The Required Voltage ；
5. Press The “Reset” Button To Block The Experimental Power Supply, Then Connect The High End Of The High-Voltage Output Test Clamp To The Live Part Of The Test Sample, And The Output Low End Test Clamp To The Insulated Part Of The Test Product.
6. Press The “Punctual/Continuous” Switch To The “Punctual” Position → Press The “Start” Button, At This Moment High Voltage Is Applied To The Sample, The Ammeter Shows The Breakdown Current Value, After The Timing Is Completed, If The Sample Is Qualified, It Will Automatically Reset; If The Test Product Is Unqualified, The High Voltage Will Be Automatically Blocked And An Audible And Visual Alarm; Press The “Reset” Button, The Audible And Visual Alarm Will Be Eliminated, And The Test State Will Be Restored.
7. After The Experiment, Cut Off The Power Supply And Arrange The Instruments.
4 Matters Needing Attention:
1. Operators At This Position Must Be Familiar With The Performance And Operating Requirements Of The Equipment. Personnel Who Are Not In This Position Are Prohibited From Operating. Operators Should Put Insulating Rubber Pads Under Their Feet And Wear Insulating Gloves To Prevent High-Voltage Electric Shocks From Causing Danger To Life.
2. The Instrument Must Be Firmly Grounded. When Connecting The Machine Under Test, It Is Necessary To Ensure That The High Voltage Output Is “0″ And In The “Reset” State
3. During The Test, The Ground Terminal Of The Instrument Must Be Firmly Connected To The Tested Body, And No Open Circuit Is Allowed;
4. Do Not Short-Circuit The Output Ground Wire With The AC Power Wire, So As To Avoid The Shell With High Voltage And Cause Danger;
5. Try To Prevent Short Circuit Between The High-Voltage Output Terminal And The Ground Wire To Prevent Accidents;
6. Once The Test Lamp And Super Leaky Lamp Are Damaged, They Must Be Replaced Immediately To Prevent Misjudgment;
7. Protect The Instrument From Direct Sunlight, And Do Not Use Or Store It In A High Temperature, Humid And Dusty Environment.
