Description
They are used to assess contact joints: circuit breaker and disconnector contacts, busbars, bolted joints and electrical machine windings. Ф4104-М1 has a current stabilizer, a measuring amplifier with a low-pass filter and a sync pulse generator. Errors are ±4 % on 0–100 µΩ, ±2.5 % on 0–1 mΩ to 0–1 Ω, and ±1.5 % on other ranges. An additional error from industrial-frequency interference is specified, which matters at operating substations. ЦС4105 has a compact plastic case, a microcontroller and an alphanumeric display, and stores 20 measurements, which suits going round many joints. Model designations are written in several ways: Ф4104-М1, Ф4104М1, Ф 4104-М1, F4104-M1, ЦС4105, ЦС 4105, CS4105. These are the same instruments.
How to choose
If you need an analog instrument with a range from 0–100 µΩ and specified interference protection, choose Ф4104-М1. If digital reading, result memory and AA battery power matter, choose ЦС4105. We match version, ranges and kit to your task and clarify verification questions. Write to a USK ENERGY manager.
