MIT series tester provides excellent level of noise immunity, test performance, and safety Essential model is suited for users performing GO/NO GO testing not needing to record test results while working in tough locations Designed for diagnostic testing and maintenance of high-voltage electrical equipment Offers unparalleled performance, safety, and reliability for OEMs, industrial companies, electrical contractors, and utility providers Intuitive user interface ensures no time is lost for remembering how to use tester Simple operation via two rotary switches and large backlight screen that displays multiple measurements simultaneously Graphical quick-start guide attached inside lid to assist first-time users Provides ±5% accuracy up to 1 TΩ at 5000V or 2 TΩ at 10000V PI predictor function reduces time needed to perform PI tests up to 50% or more The Megger MIT1015 (1016-091) Essential Digital Insulation Resistance Tester and Megohmmeter offers rugged dependability, a long service life, and accurate measurements. The "no compromise" approach offers further levels of safety than simply complying with the relevant safety standards while the intuitive color custom display allows for users to work in extreme environments with an unbeatable viewing angle.
The MIT1015 provides an excellent level of noise immunity, test performance, and safety and offers a maximum test voltage up to 10 kilovolts. This Essential range model is perfect for performing GO/NO GO testing without the need to record test results while working in tough locations.
Instrument Productivity and Accuracy
The MIT1015 offers rapid charge batteries and operation from an AC source when the battery is flat or low. An intuitive user interface ensures that no time is lost remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and a large backlight display which enables various measurement information to be displayed simultaneously. A graphical quick-start guide is provided inside the lid to assist first-time users and features QR code links to the online User Guide.
Measurement accuracy is of high importance for any insulation resistance measurement and is particularly important to ensure that the accuracy is maintained up to higher IR values that are required by some applications. This Essential range model provides an excellent ±5% accuracy all the way up to 1 TΩ at 5000V or 2 TΩ at 10000V. Users should always check that the expected range of measurements sits within the accuracy range capability of the instrument.
PI Predictor Function (PIp)
The Polarization Index test can be time consuming, with a ten minute test (30 minutes on 3-phase) and with multiple items to test, any time saved is a bonus. The PIp function helps users save that valuable time. The PI predictor function uses the first part of the IR curve to predict the rest at five minutes into the test. The PIp can start as early as three minutes into the test and will stop when it is confident in the prediction.
RE>Act Test Mode
The RE>ACT test mode feature will revolutionize the reliability of measurements. When insulation testing, it is essential that any re-absorption current from the insulation under test is fully discharged before starting the test. Remaining absorption current, depending on polarity, can result in IR measurements that are falsely high or low, with the potential to incorrectly pass any failing insulation. The RE>Act mode not only measures this reabsorption current but also provides an indication to the user of the impact it will have on the instrument's measurement range and accuracy.
Safety Features
Safety of operation is built in with this 10 kV model safety rated to CAT IV 600V up to an altitude of 3000 meters.
Dual Case
The dual case design features a tough outer case to protect the tester from knocks and drops along with a fire retardant inner case. The case IP rating prevents moisture and dust ingress when storing or carrying the instrument. The lids have velcro-on pouches ensuring that leads remain with the instrument at all times. Case lids are removable for improved access to the terminals.
Voltage Warnings
A multitude of voltage warnings help ensure user safety with five levels of warnings. Before testing has started, the instrument will provide these warnings:
Level 1: Live voltage above 30V has been applied.
Level 2: 75% of the instrument's noise limit has been exceeded, users should check filter settings.
Level 3: 100% of the instrument's noise limit has been exceeded, warnings and tests are inhibited.
Level 4: The external voltage overheating discharge resistors disconnect.
Level 5: The fifth warning is a unique one. During testing in high noise environments, induced noise surges can result in extremely high voltages being applied to the instrument. In the event that these voltages are higher than the instrument's reinforced insulation limits, the instrument will halt the test to reduce terminal voltage and warn t
