MEGGER MIT300 SERIES INSULATION AND CONTINUITY TESTERS
Digital or analogue Megger MIT300, MIT310 and MIT320 all feature the popular Megger digital/analogue display is extremely easy to use. Large 20 mm high characters provide very clear readout, combined with an analogue are for the feel of an analogue instrument, with a true analogue response.
Intelligent Safety System for protection, self contained protective cover, living circuit warning, result storage and downloading, hands free use - it is Megger MIT300 series. Combining both Insulation testing and continuity testing, each instrument caters for all aspects of fixed wiring.
Insulation ranges : 250V, 500V, 1000 V (d.c.) Measuring range : 10kΩ - 999MΩ on all ranges Test current on load : 1 mA at min. pass values of insulation Continuity measuring range : 0,01Ω-99,9Ω (0-50Ω on analogue scale) Open circuit voltage : 5V±1V Short circuit current : insulation : 1,5 mA nominal continuity :205 mA, ±5 mA Voltage range : 0 - 600V a.c. (50/60Hz) or d.c. Accuracy at 20°C : insulation & continuity : ±3%, ±2 digits voltage : ±1%, ±2 digits Resistance range : 10Ω - 1mΩ Operating temperature : -10°C to +60°C Operating humidity : 93% RH at +40°C max Battery : 8 x 1,5V cells IEC LR6 type (AA alkaline) Battery life : 5000 consecutive tests (5 second per test) Certification : BS7671, HD384, IEC364, IP54, IEC61010-1,... Dimensions : 203 x 148 x 78 mm; Weight : 980 gms |
Internal memory Over 1000 results can be saved on site, and downloaded to a computer when convenient. Data is stored in non-volatile memory; being retained when the instrument is switched off or batteries are exhausted.
AutoPower Down (MIT310, 320, 330) operated after 10 minutes if left in standby mode.
Tough Designed to take the bashing that testers receive on site, the Megger MIT insulation testers are rubber armoured.
The rigid display cover folds right out of the way during testing and locks down to protect the display when its finished.
Simple to use Simple functions. Colour coded ranges help test selection, reducing testing time and help with fault location.
Hands free use It hands comfortably around the neck for hands-free use because the instrument is carefully balanced.
Continuity and buzzer testing starts automatically on connection to the circuit.
Insulation tests being activated from the instrument or the switch probe, supplied with MIT320 and MIT330 (not suitable for the use with the MIT300 or MIT310.
Backlighting Both the display and the range selected can be read in the dark because the MIT320/330 has a backlit display and range selection.
Safety features To protect the user and the tester from incorrect use the MIT series all have an extensive range of features known as the Megger Intelligent Safety System including:
Safety Interlock - prevents unsafe connections of test leads
Safe contact detectors - even if the MIT is connected to a live circuit whilst on continuity setting the tester will remain safe and not be damaged.
Live voltage warning - alerts the operator when a circuit voltage over 25V exists.
Safety lockout - prevents the test from operating when the circuit voltage is >50V.
Continuity check - prevents a continuity test or buzzer test on a live circuit.
All the MIT instruments meet or exceed the UK and International Wiring Regulations, including requirements of BS7671 and VDE 0413 parts 1 and 4, HD 384, IEC 364, NFC15-100, NEN3140, ES59009 and EN 61557.
