Megger MTR105 Rotating Machine Tester

 

The MTR105 is a dedicated Static Motor Tester with Megger’s tried and trusted suite of insulation resistance tests (IR), plus all the great traditional features and reliability of Megger’s testers.
The MTR105 takes the test abilities of Megger’s proven IR test instruments adding DLRO four wire Kelvin low resistance test, inductance and capacitance tests to provide a versatile motor tester,all packaged in a robust hand held instrument, which up to now has simply not been available.
Additionally the MTR105 incorporates temperature measurement and compensation (for IR tests), motor direction of rotation plus supply phase rotation tests.
These new test abilities make the MTR105 a real world, versatile, hand held motor test instrument. The MTR105 comes in an over-moulded case, providing increased
protection and robustness, achieving an IP54 weatherproof rating.

*Important Calibration Information:

This instrument comes complete with the manufacturers calibration certificate. Please be aware that these certificates are generic and may also be time lapsed. If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.

Insulaton Resistance Tests

Resistance range 100 Ω up to 200 GΩ.
Supports PI, DAR, Timed and Temperature Compensation.
Stabilised insulation test voltage accurate to -0% +2%
±2 V, which provides a more accurate test voltage without
the risk of over-voltage damage to circuits or components.
The output voltage is maintained between 0 and 2%
throughout the test range.
Where a nonstandard test voltage is required, a variable
range allows the exact test voltage to be selected from
10 V up to 999 V and is subject to the same stabilised
output control.
Dedicated buzzer button either ON, VISUAL or OFF.
Adjustable buzzer for minimum resistance limit
(0.5 MΩ up to 1000 MΩ).
Buzzer sounds on test pass.


Voltmeter

Measures ac 10 mV up to 1000 V; dc 0 to 1000 V; TRMS
(15 Hz up to 400 Hz).
Three phase supply and direction of rotation.


Continuity Resistance Tests

Single automatic resistance range from
0.01 Ω to 1.0 MΩ.
Automatic test current selection uses the preferred test
current for the load resistance under test
(200 mA up to 4 Ω).
Bi-directional tests option automatically reverses the current
without reconnecting leads.
Lead resistance compensation (NULL) operates up to 10 Ω
of resistance.
Dedicated buzzer switch either ON, VISUAL or OFF.
Adjustable buzzer for maximum resistance limit
(1 Ω to 200 Ω in 12 steps).
Buzzer sounds on test pass.


DLRO 4 Wire Kelvin low Resistance

Automatic resistance range from 1 mΩ up to 10 Ω.
Selectable auto or manual test.
Bi-direction or single direction.
Bi-directional tests option automatically reverses the current
without reconnecting leads.
200 mA test current.


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 Hz or 1000 Hz. In AUTO mode, the MTR105 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 Megger web site.


Safety:

The MTR105 is designed to be exceptionally safe to use. The fast detecting circuitry reduces the likelihood of damage to the instrument if accidentally connected to live circuits or across phases.
  • Meets the international requirements of IEC61010 and IEC61557.
  • Live circuit detection and test inhibit on all measurements with user notification (except for direction of rotation measurements).
  • User selectable insulation test terminal lockout voltage 25 V, 30 V, 50 V, 75 V (default is 50 V).
  • Detection and inhibit functions when the protection fuse has failed.
  • Suitable for use on CAT III applications and supply voltages to 600 V.
