MIT415
Insulation Tester
DESCRIPTION
The new Megger MIT415 insulation and continuity tester
has been designed for electrical testing by utilities,
industrial, commercial and domestic electricians. The wide
range of test voltages makes the MIT415 series ideal for the
engineer or technician involved with combined applications
of both communications circuits and power circuits such as
would be found in elevator service/repair and routine main-
tenance. The low test voltage insulation ranges also makes
the MIT415 ideal for ESD testing.
The MIT415 replaces the well-established BMM2000ESD
insulation tester, gives greater functionality with simplified
operation, greater application range and an ergonomically
designed case.
INSULATION TESTING
nTest voltages -10 V, 25 V, 50 V, 100 V, 250 V and 500 V
nTest Lock -Locks insulation test on continuous.
nTest voltage display -The actual test voltage is displayed
on the smaller digital readout, with the insulation result
on the larger digital display.
nAnalogue arc -The display also features an analogue arc
to replicate the response of a moving coil display.
nPI and DAR - Polarisation Index (PI) and Dielectric
Absorption Ratio (DAR) functions
n50 GΩ-Insulation testing from 1 GΩto 50 GΩ
nSilicone leads -High quality flexible silicone test leads
are comfortable to use and prevent measurement er rors
on higher GΩranges.
nTest inhibit -prevents testing if system voltages in excess
of 50 V are detected when making insulation tests.
nInsulation buzzer -The buzzer can operate if the
insulation resistance is above a preset limit, set via the
Setup menu.
CONTINUITY TESTING
nAuto-test -Auto test on circuit contact enables real two
handed operation without the need to press the test
button.
n200 mA or 20 mA -Either 200 mA or 20 mA continuity
test currents are available. 20 mA test cur rent will
considerably increase batterylife.
nLead null -Lead resistance compensation (NULL)
operates up to 10 Ωof resistance.
nBuzzer -ON-OFF selected by simple push button.
nBuzzer limit -Continuity buzzer limit alarm provides
adjustment of the maximum resistance at which the
continuity buzzer sounds. This is adjustable from 1 Ωto
20 Ωin 5 steps.
nResistance - kΩrange extends continuity measurement
to 1 MΩ.
n10 V and 100 V ESD testing
n25 V & 50 V signal cable insulation testing
n250 V & 500 V Insulation testing up to
50 GΩ(500 V)
nContinuity testing at 200 mA or 20 mA
from 0.01 Ωto 999 kΩ
nDC and TRMS AC voltage measurement
nLarge backlit display
nCombined analogue and dual digital
readout
nWeatherproof to IP54
nSupplied with AA alkaline cells

DISPLAY
The display offers a combination of analogue arc and a dual
digital readout:
Analogue arc:
nFull display width analogue arc.
nPatented arc display shows essential charge and discharge
characteristics not visible on a digital numeric only
display.
nSingle pointer “needle” response is similar to a moving
coil meter.
nLogarithmic display for better low insulation value
measurements.
Dual digital display:
nLarge main digital readout for good visibility of all main
measurement results
nSecond digital display for additional data such as:
Insulation test voltage.
Insulation leakage current.
Supply frequency (when measuring volts).
Test mode eg. PI, DAR or TI (Timed mode).

SAFETY
Designed to be exceptionally safe to use, fast detecting
circuitry prevents damage to the instr uments if accidentally
connected to live circuits or across phases. Specifically, all
instruments:
nMeet the international requirements of IEC1010-2 and
EN61557.
nLive circuit detection inhibits insulation testing on circuits
above 50 V.
nLive circuit detection and test inhibit on continuity
measurements.
nDefault display of live circuit voltage on all ranges.
nDetection and inhibit functions even if the protection
fuse has failed.
nSuitable for use on CAT IV applications and supply
voltages (of up to) 600 V to ground.
