Fast & Reliable
Ideal for many applications, this rotating machine tester features a guard terminal, to eliminate any surface leakage current and detachable test leads with interchangeable clips and probes. Additionally, test results can be downloaded to a USB storage device, which can be accessed by connecting to a PC.
Features
Safety
Insulation Resistance Tests
Voltmeter
Continuity (Resistance) Tests
DLRO Four Wire Kelvin Low Resistance
Motor Direction of Test
Tests the direction of rotation of the motor under test and displays the phase sequence on screen. The connected motor is rotated in one direction and the display shows sequence of the phases of rotation. The motor is next rotated in the opposite direction, the phases are checked again and shown on the display.
Inductance, Capacitance and Resistance Meter (LCR)
Auto inductive, capacitive and resistive test. Frequency selectable to 120 or 1000 Hz. In AUTO mode, the unit automatically determines if the main element of the load is inductive, capacitive or resistive and displays the result on screen. Selectable inductance and capacitance test.
Temperature
Temperature measurement of unit under test, via the supplied thermocouple, allows temperature compensation to be applied in insulation resistance tests.
Display
Full colour graphic display makes the MTR105 simple to understand and easy to use.
Guard Terminal
The guard terminal (G) is a third terminal on the connection panel. Connection of the guard terminal, on certain applications, provides a return path for parallel leakage currents, which could otherwise create significant errors in the insulation measurement. This is especially so for surface contamination of equipment or cables.
Storage and Download of Results
Test results can be downloaded to a USB mass storage device, which can be accessed by connecting to a PC or a Laptop running PowerDB.
Instrument Software Updates
Occasional information bulletins and software updates may be issued on the web site.
