Customer Questions & Answers
What is included in the Victor 4105A meter box, and what are its approximate dimensions and weight?
The Victor 4105A box normally includes: the digital meter, three earth stakes, three test leads of different colours and lengths, a user manual and a carry case. Its usual dimensions are around 150×70×125 mm and the weight, including accessories, is about 1.2 kg. I recommend checking with the distributor whether these accessories are guaranteed.
Does the Victor 4105A require direct mains power or does it run on batteries? Is it compatible with TT, TN and IT earthing systems?
The Victor 4105A meter runs on AA batteries (normally 6×1.5 V), making it portable and safe for field use. It is suitable for checking earthing installations in TT, TN and most IT configurations, provided the reference electrodes can be physically accessed.
What should be considered to ensure reliable measurements and avoid common errors during use?
For accurate results, it is essential to position the stakes correctly as specified in the manual (recommended distances of 5–10 m) and ensure the cables are properly connected. Avoid measuring in excessively dry or stony ground, and check the battery condition before starting. Local electrical interference can affect the measurement, so it may be necessary to repeat tests at different points.
What safety standards or certifications does this meter comply with, and are spare parts or after-sales service available?
The Victor 4105A usually complies with international electrical safety and measurement standards such as IEC 61010-1 and CE regulations. However, the exact certification may vary by batch or country, so it is advisable to request a copy of the certificate from the distributor. Common spare parts (cables, stakes) are easy to find, and technical service is usually available for maintenance or calibration.
What is the Victor 4105A earth resistance tester used for?
It is used to measure insulation resistance to earth in electrical installations, ensuring the safety and proper operation of the system.
What accessories are included with the Victor 4105A tester?
It includes 2 earth stakes, 3 long test leads, 2 short test leads, 8 1.5V batteries and a carrying case.
What measurement ranges does the unit have?
