Typical application is measuring of protective earth resistance of equipment in compliance with IEC 61010-1 safety standard.
Other application is measuring resistance of:
High, middle and low voltage circuit breakers
High, middle and low voltage disconnecting switches
High-current bus bar joints
Cable splices
Welding joints
System Overview:
The RMO60E is ideal for testing protective bonding (grounding) of equipment following the standard IEC 61010-1.
The RMO60E generates true DC current with automatically regulated test ramps. During the test RMO60E ramps with increasing current before measuring and decreasing current after the measurement. This eliminates magnetic transients.
After the test current has been set, pressing the Ω button starts the automatic test procedure.
The RMO60E instrument can store up to 500 measurements. All measurements are time and date stamped.
Using DV-Win software a test can be performed from a PC, and the results can be obtained directly at a PC.
Communication between RMO60E and PC is through USB or RS232 cable. Using DV-Win the result can be arranged as an Excel spreadsheet that can be later shown as a diagram and printed for a report.
The set is equipped with thermal and overcurrent protection.
The RMO60E has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing proprietary
DV-Win Software:
RMO DV-Win Software provides several advanced features as a supplement to multiple functions of RMO devices.
Testing in Continuous mode is upgraded with a sample time feature which allows user to record test results in specific time intervals set in seconds.
After performed measurements results can be saved in a various formats and test report can be generated and saved or printed.
Result can also be downloaded from the device to the PC by use of several different search filters.
For the RMO form of DV-Win software there is Help menu available, with detailed instructions and explanations of all functions and features.
