Motwane’s Digital Contact Resistance Meter, Model PCRM-100S is specially designed to measure extremely low resistances in micro ohms. The instrument is based on the Kelvin four wire connection method for the measurement of low resistance. The selectable current injection is 100A. PCRM 100S has a large LCD with a backlight and displays real-time test information like injected current with measured resistance value & voltage drop. This user friendly instrument comes with heavy duty cables with clamps for accurate measurement and can be easily transported in its transportation case. Advanced Windows based software is provided for data downloading, analysis, and report generation. Internal memory of 99 records is provided for onsite data storage along with an in-built thermal printer to print the test results on the field.
PCRM 100S has a dual ground technique to test circuit breakers with both sides grounded, which makes it safer to conduct tests in substations
PCRM 100S has a Bluetooth connectivity module with Motware mobile app for remote access of testing data & storage in the cloud for further analysis & record purposes.
Stationary and moving contacts are built from alloys that are formulated to endure the stresses of electrical arcing. However, if contacts are not maintained on a regular basis, their electrical resistance due to repeated arcing builds up, resulting in a significant decrease in the contact’s ability to carry current and an increase in resistance. Excessive corrosion of contacts is detrimental to the breaker’s performance. Hence to check contacts, apply DC and measure the contact resistance or voltage drop across the closed contacts. The use of a higher current value gives more reliable results than using lower current values. The resistance value is usually measured in micro ohms (μΩ).
PCRM-100S is specially used to measure static contact resistance of LV, HV, EHV circuit breaker contacts installed in energized switchyards. High accuracy and repeatability make it a reliable tool for quality assurance and easy operations. It is a very handy tool for quick maintenance checks in various industries.

Motware Cloud Application
Motwane has designed and developed MOT-WARE – a cloud-based Test Data platform to aid in accurate Asset Health Assessment. Through Motware, the Test and Measurement industry has taken a huge leap forward. It is a revolution in the way tests are conducted and the way data is analyzed.
MOT-WARE captures data from a full range of BLE Enabled Motwane Testing Equipment. It is accessible from web based applications, desktop applications, and mobile applications. In addition, it offers an open architecture that can seamlessly integrate with any non Motwane Test and Measurement equipment for quick and authentic digital test data. Data can be captured periodically as well as be streamed in real-time via sensors from IoX’n Series of IoT devices. (link to Ioxn page)
Some of its features include a pre-loaded repository of test templates for various assets as well as customizable test templates. A customized report builder in MOT-WARE allows users to create reports that can be designed and generated as per their desire. MOT-WARE also has a facility to upload test data history and the breakdown history of the assets. Tests can also be viewed in various metrics such as Pass/Fail.
Digital test data enables data analytics and visualization which offers multiple statistical advantages. It improves productivity & efficiency, enables cost reduction, and improves asset life. Data analysis done through MOT-WARE includes trend analysis, MIS reports, and pivot tables. As an add-on, MOT-WARE also offers ‘Motwane AI Analytics’(Link to AI Analytics page) which uses a proprietary AI algorithm and Machine Learning to make accurate predictions about your asset’s life based on its behavioral patterns and operating conditions.
MOT-WARE can be used for various applications across customer segments like Utilities, OEMs, Industries, Electrical contractors (Testing, O&M) or Field repairs & service providers, EPCs, commercial premises, and many more.
