The KoCoS PROMET SE Precision Micro Ohm Meter weighs just 1.5 kg and features a compact housing fitted with a carrying strap, it can even be used in situations where it cannot be put down, for example when working on ladders or hoisting platforms. The powerful lithium-ion battery guarantees operation independent of the power supply even for periods of several hours and longer.
Determination of resistance at two measurement points
Because the device is equipped with two current outputs and two voltage measurement inputs, it is possible to carry out parallel measurements at two measurement points in order to be able to assess the quality of connections, for example. In addition, when used in combination with an ACTAS switchgear test system, up to six main contacts can be tested in parallel.
Constant test currents up to 200 A
A current source based on state-of-the-art power electronics and capacitor technology provides constant output for test currents up to 200 A, even during battery operation. The test currents are load-independent and adjustable.
Assessing the quality of connections
Because there are two voltage measurement inputs, the quality of connections such as screw connections on busbars can be determined quickly and easily using the quality factor. The quality factor is defined by the ratio of the resistance of the connection over the overlap length to the resistance of the busbar over the same length.
Measurement with temperature compensation
The KosCoS PROMET SE can measure resistances with temperature compensation. The temperature at the measurement point is measured using a sensor and the resistance value is calculated for the reference temperature. A material database for the temperature compensation of various different materials is saved in the device and can be extended as and when needed.
Precise determination of contact resistances
Regular measurements of the contact resistance allow an accurate assessment of the condition of contact systems. Using PROMET SE, excessively high transfer resistances resulting from poor connections can be identified by measuring the static contact resistance. This ensures that maintenance requirements can be identified at an early stage and down times kept to a minimum.
Simple and intuitive operation
The resistive 3½“ touch screen and function keys make for simple and intuitive operation. All test parameters are displayed clearly and can be set directly. The resistance values determined during measurements are displayed as results on the screen and can be saved in the internal memory with a time and date stamp.
Results management and test report output via PC
PROMET SE can be connected directly to a PC. Downloading and managing the data saved in the device is made easy by the user-friendly software. The measurement results, which are displayed in a clearly structured form, can also be exported to an Excel spreadsheet or presented in a test report.
