INTRODUCTION 4 – 0

Raytech Digital Micro-ohm meter, Micro-Centurion 2 (MC2), was designed for a high degree of

accuracy for the measurement of very low resistance. This technology was then packaged into a portable test system for use by apparatus manufacturers, rebuild shops, and electrical maintenance crews.

Ease of use: This intelligent system has an easy to use operation screen, which allows quick selection of the current level and resistance level to be measured. The system has the ability to detect the resistance level and suggest the correct range to select which provides for extremely accurate results.

Impressive Accuracy: The MC2 is a high precision, fully automatic, microprocessor based system. This system is designed for highly accurate readings on-site with laboratory precision.

Unique Measuring Technique: This newly designed technique of measurement incorporates a high precision measurement circuit and modular power source. Extensive filtering and high precision standards are used within the test system. The system is capable of precision measurements to 200 A.

Operation: The MC2 applies a preset current level and resistance range selected by the user. The results of the test are displayed within a few seconds automatically. The results are reported on the easy to read liquid crystal display and can be stored or printed out.

Compact Design: The MC2 is one of the most lightweight systems available that comes complete with its own rugged waterproof Fieldcase.

Simple Maintenance: There is No maintenance required. There is No calibration procedure (No potentiometers to turn). This is due to the utilization of high precision components in the design.

Advanced Protection: Upon powering on the system initializes itself with a self-calibrating, circuit checking sequence. If any problems are detected during this initialization period, or during operation, the operator is immediately notified. The system constantly monitors the condition when turned on. The MC2 has extensive protection built in to the circuitry. This is one of the many reasons we can extend our warranty to 5 years.

Advantages & Features:

Highest accuracy and Precision of any high current test system Automatic measurements of Low Resistance from 0.01 ...5 Microprocessor based system with internal storage for over 2000 test results Single or continuous measurements with automatic data storage User can preset a number of tests, at various timed intervals, for automatic data storage Printing and Storage of test results while the test system is measuring Complete automatic calibration system and system diagnostics Standard Centronics (Parallel) Interface & RS232 (serial) Interface Pure filtered DC Power source for the highest accuracy readings Automatic, high efficiency cooling system to dissipate internal temperatures Automatic shut off for over-temperature condition Panel mounted Emergency Stop Switch Wide input power source range Lightweight and Portable, Less than 33 lbs 5 Year standard warranty

SYSTEM DETAILS: 5 – 0

System Check:

The instrument is Line operated. The system is designed to be used with voltage power sources (mains power) between 100-250 vac 50/60Hz. The system performs a self check each time that it is powered on. The user should always visually inspect all connectors, cables and devices to be measured to avoid any safety issues.

Limitations of Resistance Testing:

The Test system is capable of sourcing 200 amperes DC. The current test leads should have a total resistance not exceeding 40 milliohms. Beyond the 40 milliohms the test set decreases the available output current at lower current settings. A warning message may appear:”Use 10 Amp

range”. The system is just letting the user know that the selected current output that the user

wishes to use may not be 100%. However, the system will continue to measure and display a less accurate result. If the message”Rx Too High” or “+++.+”is viewed in the display, then mandatory range switching must be complied with to continue to test.

Transformer windings:

Use of the MC2 for high inductive winding resistance is not recommended. The inductive characteristics of transformer winding testing require a long period to saturate the winding to get a stable reading. In addition, care must be taken when removing test leads such that a voltage charge does not remain on the winding. Lethal currents might remain and may cause personal injury and possibly damage the instrument. Specialized test sets with heavy duty discharge circuits and higher potential compliance voltages and current should be considered for winding resistance measurements (Raytech WR50 Series of test instruments).

Do not use test probes (MJ04 or other) when testing Inductive loads (Motors, transformers) or at current levels above 10 amperes. Consult the factory for additional information.

Low Resistance Testing:

The MC2 is an extremely useful device for checking Switch Contacts, SF6 Switchgear, Bus bars, Splices, Joints, Fuses, Breaker contacts, Rail bonds, and Low inductive windings.

The MC2 utilizes a 4 wire measuring technique. The Two (2) connections on the front plate marked +I & -I are the current leads. The Two (2) connections on the front plate make +P & -P are the Potential or Voltage leads. By connecting a test specimen to the Current leads (See figure

1) and applying the Potential leads across the resistance to be measured. The points where the

potential leads are connected determine the resistance reading.

Figure 1

The test set employs a very simple principle of Ohm’s law: R=V/I

R = Resistance, V = Voltage, I = Current

TEMPERATURE PROBE: 11 – 0

(Option 2021N-26001)

This probe can be purchased for the MC2 for the purpose of recording temperatures. Recording the temperature of the device under test is highly recommended due to the characteristics of the increase of resistance of a metallic object as its temperature increases. There are temperature compensation tables for Copper and Aluminum available to calculate the conversion factor (See page 16 for this option). The MC2 is a very accurate and precise test system. To take full advantage of this high accuracy, the temperature of the device under test should be recorded.

The temperature probe is mounted to a flexible extension cable that plugs into the front panel of the MC2. This option enables the user to record the ambient temperature or the actual temperature of the device under test.

The MC2 will automatically sense when the optional temperature probe, 2021N-26001, is connected to it. The temperature will be displayed on the instrument screen during a test and will appear when a print report is requested. The temperature, as well as the test results, can be saved into memory. The temperature can only be viewed during a test and on a printed report.

The actual temperature measured is displayed and can be saved into memory.
