Overview
The SMART SENSOR AR3125 high voltage insulation resistance meter is an insulation resistance tester widely used to measure the insulation resistance of generators, motors, power transformers, wiring, appliances and other electrical installations. It is often used in routine maintenance procedures to indicate the change of motor insulation resistance over time to predict potential failures and to calibrate regularly to ensure instrument accuracy.
Features
1. Multi-speed output voltage selection: 500V, 1000V, 2500V, 5000V, covering a wide Measurement range.
2. High Accuracy measurement: Accuracy is +/- 5% rdg +/- 3dgt to ensure Test Reliability.
3. Multifunctional test: Support AC/DC voltage test, polarization index function, and have LCD backlight display and high voltage probe.
4. Safety protection: Provide overload protection and voltage resistance, the maximum short-circuit current is 1.3mA, enhancing the safety of use.
5. Portable design: Encasement with suitcase, Net weight 988g, easy to carry and operate on site.
Principle
The high voltage insulation resistance meter measures the resistance value of the insulating material by applying a high voltage direct current to the electrical equipment under test. The process is based on Ohm's law and detects current leakage to evaluate insulation performance. The meter generates a stable high voltage through an internal circuit and uses an LCD to display measurement results to help users identify changes in insulation resistance.
Applications
Power industry, cable installation and maintenance, generator testing, industrial equipment testing, scientific laboratories
Steps
1. Prepare the equipment: ensure that the high voltage insulation resistance meter has sufficient power supply (use DC12V battery), and check the high voltage probe connection.
2. Select the output voltage: according to the requirements of the tested equipment, select 500V, 1000V, 2500V or 5000V gears.
3. Connection test: Connect the high voltage probe to the insulating part of the electrical device under test to ensure safe contact.
4. Start measurement: start the meter, observe the LCD display, and record the insulation resistance value.
5. Analysis results: Compare measurement data with Standard values to evaluate insulation performance.
6. Turn off the device: After the test is completed, turn off the power and store it properly.
Notice
Make sure the equipment is in good condition before use and avoid operating in humid or dangerous environments.
• Pay attention to the risk of high voltage during testing and wear appropriate protective equipment to prevent electric shock.
• Regularly calibrate the meter to maintain measurement accuracy.
• Avoid overloading and prevent damage to equipment.
• Store in a drying environment to avoid strong Impact.
