Insulation/Continuity Tester with Storage, 50V/100V/250V/500V
Megger MIT481/2-LG
Insulation/Continuity Tester with Storage, 50V/100V/250V/500V
The Megger MIT4812 Insulation and Continuity Tester replaces the original MIT480 and is designed specifically for the Telecommunications and Cable testing markets. The tester features a redesigned case, back-stand, and 6-cell battery compartment with separate fuse access. This unit is over-molded for increased protection and to achieve an IP54 weatherproof rating.

The Megger MIT481/2 (1004-741) Insulation and Continuity Tester replaces the original MIT480 and is designed specifically for the Telecommunications and Cable testing markets. The tester features a redesigned case, back-stand, and 6-cell battery compartment with separate fuse access. It is over-molded for increased protection and to achieve an IP54 weatherproof rating.
Three Terminal Connection:
Three terminal measurement permits the connection of all three test leads for A, B and E (or Tip, Ring and Ground). The measurement pair is selected from the A-B-E (T-R-G) button on the front panel. Selection is confirmed in the display. No disconnection of test leads to measure individual pairs is required.
Insulation Resistance Testing:
The feedback-controlled insulation test voltage is now accurate to +2% -0% compared to the original +20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits. A variable range allows the exact test voltage to be selected from 10V up to 500V.
Features Include:
Test voltages - 50 V, 100 V, 250 V, and 500 V.
Variable test voltage - Adjustable test voltage from 10 V to 500 V.
2% test voltage accuracy - The output test voltage is maintained within the tolerance or 0% +2% +2 V
PASS/FAIL indication - PASS or FAIL displayed depending on threshold voltage
Stabilized test voltage - The voltage is feedback controlled to ensure it remains within specification throughout the full test range
Test voltage display - The actual test voltage is displayed on the smaller digital readout, with the measurement on the larger digital display.
Test range - Insulation testing up to 100 Gandohm; @ 500 V.
Measurement range displayed - The test range is displayed during selection
Measurement voltage display - The measurement voltage is displayed during the test
Analog arc - The display also features an analog arc to replicate the response of a moving coil display.
Timed testing - Automatically test to a time limit
Silicone leads - High quality flexible silicone test leads are comfortable to use and prevent measurement errors on Gandohm; ranges above 5 Gandohm;.
Test inhibit - prevents testing if voltages in excess of 25, 30, 50, 75 or 100 V (set by the user) are detected when making insulation tests. Default is 50 V.
Insulation buzzer - The buzzer can be set to buzz if the insulation resistance is above a user adjustable limit, set in the Setup menu.
Test Lock - Holds insulation test on continuously
Continuity (Resistance) Testing:
Single resistance range - One range fully automatic from 0.01 andohm; to 1.0 Mandohm;.
200 mA or 20 mA - Either 200 mA or 20 mA continuity test currents are available. 20 mA test current will considerably increase battery life.
Lead null - Lead resistance compensation (NULL) operates up to 10 andohm;s of resistance.
Buzzer - ON/OFF selected by simple push button.
Buzzer limit - Continuity buzzer limit alarm provides adjustment of the maximum resistance the continuity buzzer sounds. This is adjustable from 1 andohm; to 200 andohm; in 12 steps.
Differential measurement - Allows the difference between two consecutive continuity tests to be measured
REN - Displays the appropriate REN value for the circuit under test.
Available on 100 V ins or continuity range
Voltage Measurement:
True RMS voltage measurement to 600 V ac or dc with resolution from 0.1 mV.
Digital voltage measurement up to 600 V ac/dc
Analog arc measurement to 600 V ac/dc
Automatic display of frequency during voltage measurement.
Input impedance is 10 Mandohm; to prevent loading the circuit and reporting low voltages.
Current Measurement:
andoslash; - 400 mA AC/DC
