- 系統介紹：
- RMO-A系列微歐姆計能以自動調節的測試斜變模式，產生真正DC無漣波電流 - 在一個測試中的測量前，RMO-A是以增加的電流斜升，測量後，是以減少的電流斜降，這可明顯減少磁性暫態。

- 主電源：
-
- Lightweight – from 7 to 8 kg / 15.4 to 17.5 lbs
- Powerful – up to 600 A DC
- Measuring range 0.1 μΩ – 999,9 mΩ (up to 6 Ω)
- Resolution 0,1 μΩ
- Typical accuracy ± (0,1 % rdg + 0,1 % FS)
- Three separate test modes: SINGLE / CONTIN / DTRtest modes
- Mechanical protection IP43
- RMO-A series contain 6 models of powerful and lightweight micro ohmmeters: RMO100A, RMO200A, RMO300A, RMO400A, RMO500A and RMO600A. The main difference between these models is the maximum test current that can be generated.
- Application：Typical application is measuring resistance of non-inductive test objects:
- High, middle and low voltage circuit breakers (live and dead tank)
- High, middle and low voltage disconnecting switches
- High-current bus bar joints
- Cable splices
- Welding joints
- Fuses
- System Overview:
- RMO-A generates a true DC ripple-free current with automatically regulated test ramps. During a test the RMO-A ramps with increasing current before measuring and decreasing current after the measurement. This eliminates magnetic transients.
- The RMO-A instrument can store internally up to 500 measurements. All measurements are time and date stamped.
- Using the DV-Win software a test can be performed from a user’s PC, and the results can be obtained directly on the PC.
- Communication between the RMO-A and a PC is through an USB (as standard) or an RS232 cable (as an option). Bluetooth communication interface is also available as an option.
- Using the DV-Win the result can be arranged as an Excel spread-sheet which can be later shown as a diagram and printed for a report.
- The set is equipped with a thermal and an overcurrent protection. The RMO-A has a very high ability to cancel electrostatic and electro-magnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing a proprietary hardware and software.
- DV-Win Software (*included in the purchase price):
- Full control of the device in test
- Test raports available in several formats
- Several filters for results download to a PC
- Test plans
- Sampling time feature for CONTIN mode
- Detailed Help menu
