Megger MIT481/2 Insulation/Continuity Tester

About this item

Product Description

The Megger MIT481/2 (1006-752) 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 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.

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 GΩ @ 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 GΩ ranges above 5 GΩ.

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 Ω to 1.0 MΩ.

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 Ωs 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 Ω to 200 Ω 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 MΩ to prevent loading the circuit and reporting low voltages.

CURRENT MEASUREMENT:
ø - 400 mA AC/DC
