Megger IMT100 Offers

The industrial multi tester is a versatile instrument with a complete suite of insulation and low resistance testing capabilities, plus continuity, inductance, capacitance, voltage, and temperature measurements. Additionally, the instrument can test insulation resistance from 100 Ω up to 200 GΩ, with test voltages of 50, 250, 500 V, 1 kV, and selectable variable voltage. The instrument includes a guard terminal, and supports several diagnostic insulation resistance functions including spot reading, polarisation index ratio, and timed insulation testing.

The multi tester comes with a unique four-wire digital low resistance function that includes a stable power supply that can deliver 200 mA in long circuits with a resistance range from 1 mΩ up to 10 Ω. This unit offers different test modes selectable through a soft keypad, including bidirectional, unidirectional, automatic, and continuous. The rotary switch and soft keypads are easy to operate, with or without gloved hands, and the instrument’s full colour graphic display makes it easy to select functions and take readings. 

The unit also has a supplied thermocouple (CAT III to 600 V) that enables you to test temperature and insulation resistance compensation. What’s more, the LRC function allows the IMT100 to automatically determine if the main element of the load is inductive, capacitive, or resistive, and displays the result on screen. It also gives you the ability to select each function and frequency of 120 to 1000 Hz.

• 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, while lead resistance compensation operates up to 10 Ω of resistance
• Dedicated buzzer switch either ON, VISUAL or OFF, adjustable buzzer for maximum resistance limit (1 to 200 Ω in 12 steps) and buzzer sounds on test pass
• DLRO four 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 rotation: Tests the direction of rotation of a motor under test and displays the phase sequence on screen
• Inductance, capacitance and resistance meter (LCR): Auto inductive, capacitive and resistive test, frequency selectable to 120 Hz or 1000 Hz
• In AUTO mode, the multi tester automatically determines if the main element of the load is inductive, capacitive, or resistive and displays the result on screen and selectable inductance and capacitance test
• Guard terminal: The guard terminal (G) is a third terminal on the connection panel that provides a return path for parallel leakage currents, which could otherwise create significant errors in the insulation measurement (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
• Safety: The multi tester is designed to be exceptionally safe to use, with fast detecting circuitry reduces the likelihood of damage to the instrument if accidentally connected to live circuits or across phases
• Live circuit detection and test inhibit on all measurements with user notification (except for direction of rotation measurements)
