Detailed Product Overview
In installation and maintenance work, insulation resistance testing is required when checking wiring, distribution boards, motors and electrical equipment after repairs or during periodic inspections. For many electricians, analog insulation testers remain a practical choice for straightforward measurements because the needle movement provides an immediate visual indication of insulation behaviour during the test. The direct mechanical display allows gradual changes in insulation resistance to be observed clearly during measurement.Analog Needle Display
The analog needle display allows the insulation resistance to be assessed directly during the measurement. The movement of the needle shows how the insulation resistance changes while the test voltage is applied, which can help identify unstable or slowly rising insulation values.Protective Conductor and Voltage Check
Protective conductor testing is performed with a 200 mA test current in accordance with EN 61557-4. The defined test current applies a load to the protective conductor connection and helps detect increased contact resistance or poor connections.Designed for Practical Field Work
The 3490 complies with CAT III 600 V and is designed for use in electrical installations and service work. The instrument is powered by four AA batteries and provides approximately 20 hours of continuous operation under typical test conditions.- 3490 Analog Insulation Tester
