A variable rage allows the exact test voltage to be selected from 10 V up to 500 V. FEATURES INCLUDE: Test voltages (New) - 50 V, 100 V, 250 V, ad 500 V. Variable test voltage (New) - Adjustable test voltage from 10 V to 500 V. 2% test voltage accuracy - The output test voltage is maitaied withi the tolerace or -0% +2% +2 V. PASS/FAIL ( / ) idicatio (New) - PASS or FAIL ( / ) displayed depedig o threshold voltage. Stabilized test voltage - The voltage is feedback cotrolled to esure it remais withi specificatio throughout the full test rage. Test voltage display (New) The actual test voltage is displayed o the smaller digital readout, with the measuremet o the larger digital display.
Test rage - Isulatio testig up to 100 GΩ * @ 500 V. Measuremet rage displayed (New) - The test rage is displayed durig selectio. Measuremet voltage display - The measuremet voltage is displayed durig the test. Aalog arc - The display also features a aalogue arc to replicate the respose of a movig coil display. Timed testig - Automatically test to a time limit. Silicoe leads - High quality flexible silicoe test leads are comfortable to use ad prevet measuremet errors o GΩ rages above 5 GΩ. Test ihibit - Prevets testig if voltages i excess of 25, 30, 50, 75 or 100 V (set by the user) are detected whe makig isulatio tests. Default is 50 V. Isulatio buzzer - The buzzer ca be set to buzz if the isulatio resistace is above a user adjustable limit, set i the Setup meu. Test Lock - Holds isulatio test o cotiuously. * Gated access prevets accidetal selectio. Test rages exted from 10 GΩ to 100 GΩ depedig o test voltage as below: 50 Volts up to 10 GΩ 100 Volts up to 20 GΩ 250 Volts up to 50 GΩ 500 Volts up to 100 GΩ CONTINUITY (RESISTANCE) TESTING Sigle resistace rage (New) - Oe rage fully automatic from 0.01 Ω to 1.0 MΩ. 200 ma or 20 ma - Either 200 ma or 20 ma cotiuity test currets are available. 20 ma test curret will cosiderably icrease battery life. Lead ull - Lead resistace compesatio (NULL) operates up to 10 Ωs of resistace. Buzzer - ON/OFF selected by simple push butto. Buzzer limit - Cotiuity buzzer limit alarm provides adjustmet of the maximum resistace the cotiuity buzzer souds. This is adjustable from 1 Ω to 200 Ω i 12 steps. Differetial measuremet (New) - Allows the differece betwee two cosecutive cotiuity tests to be measured REN (New) - Displays the appropriate REN value for the circuit uder test. Avaliable o 100 V is or cotiuity rage VOLTAGE MEASUREMENT True RMS voltage measuremet to 600 V ac or dc with resolutio from 0.1 mv. Digital voltage measuremet up to 600 V ac/dc Aalog arc measuremet to 600 V ac/dc Automatic display of frequecy durig voltage measuremet. Iput impedace is 10 MΩ to prevet loadig the circuit ad reportig low voltages. (New) CURRENT MEASUREMENT ø - 400 ma AC/DC DISPLAY The display offers a combiatio of aalog arc ad a dual digital readout: Aalog arc: Full display width aalog arc. Aalog arc display shows essetial charge ad discharge characteristics ot visible o a digital display. Sigle poiter eedle respose is similar to a movig coil meter. Setup fuctios allow cotrol of Buzzer limit alarms, Cotiuity test currets, kω/mω/gω. Dual digital display Large mai digital readout for good visibility of all mai measuremet results Secod digital display for additioal data such as: Isulatio test voltage. Isulatio leakage curret. Supply frequecy (whe measurig volts). Differetial measuremet result display OTHER FUNCTIONS AND FEATURES Weatherproof - Every tester is sealed to IP54, providig a weatherproof case to reduce the chaces of water igress, icludig the battery ad fuse compartmet. Tough housig - Rubber over mouldig combies the tough shock absorbig outer protectio with excellet grip, o a strog modified ABS housig, providig a almost idestructible case. Batteries - Battery requiremets are 6 AA batteries of either stadard Alkalie or Nickel Metal Hydride (NiMH) rechargeable type, providig a miimum of 3000 isulatio tests at 500 V. VARIABLE INSULATION VOLTAGE TESTER * The variable mode provides a uique solutio for awkward isulatio voltage measuremet applicatios. The rage optio allows a isulatio test voltage from 10 V to 500 V i 1 V steps. STORAGE AND DOWNLOADING RESULTS Revised Bluetooth ad pairig procedures have made the MIT480/2s far easier to pair ad dowload data.* The test results are dowloaded to a CSV file which ca the be opeed as a Excel spreadsheet.*
