Features:Able to measure DC/AC voltage， resistance and perform continuity and insulation test.Insulation test lock， to perform the insulation test until the test lock is unlocked.Timer function， insulation test will stop automatically when the preset time is up.Storing test data， to save 20 data and memory code from 00 to 19.Reading test data， to display the data in memory.Delete data， to delete selected data.Data compare with the preset value limit.Data holding function， to freeze the displayed value.Relative measurement， to show the difference between actual value and relative base.Able to select and review maximum， minimum and average value.Able to measure the DAR and PI value.Automatic power off to conserve battery power.LCD display with analog bar and backlight.Low battery indication.Solid case is shake-proof and skid-proof.Note:1. Lock function is invalid when timer function is selected.2. When the input terminals is "Hi" and "Lo"， the overload protective voltage is 600V. When the input terminals is "V" and "COM"， the overload protective voltage is 1200V under the voltage test. In other test mode， the overload protective voltage in 250V.Specifications: Voltage measurement range 1000V DC voltage， 750V AC voltage Insulation measurement range 0.01M to 10.0G Insulation test voltages 50V， 100V， 250V， 500V， 1000V Insulation short-circuit test current 1.8mA nominal Insulation test automatic discharge time Capacitance (C) = 1 F or less， discharge time < 1 second Insulation live circuit detection Inhibit test if terminal voltage > 20V prior to initialization of test Insulation maximum capacitive load Operable with up to 1 F load Insulation Output voltage Range Resolution Test current Accuracy 50V020% 020M 0.01M 1mA@50K ÷(3%+5) 2050M 0.1M 100V020% 020M 0.01M 1mA@100K ÷(3%+5) 20100M 0.1M 250V020% 020M 0.01M 1mA@250K ÷(3%+5) 20200M 0.1M 200250M 1M 500V(020%) 020M 0.01M 1mA@500K ÷(3%+5) 20200M 0.1M 200500M 1M 1000V(020%) 0200M 0.1M 1mA@1000K ÷(3%+5) 2001000M 1 M 1.005.00G 0.01G ÷(5%+0.1G) 5.0010.00G 0.01G ÷(10%+0.2G) DCV Range Resolution Accuracy 200V 0.1V ÷(0.5%5) 1000V 1V ÷(0.5%5) ACV Range Resolution Accuracy (50~60Hz) 200V 0.1V ÷(1.5%5) 750V 1V ÷(1.5%5) Resistance Range Resolution Accuracy 20 0.01 ÷(1%5) 200 0.1 ÷(1%5) Power supply 6 * AA 1.5V battery (not included) Storage temperature -40 -60 Operating temperature 0 40 Storage altitude Max. 12000m Operating altitude 2000m 1000V CAT III， 3000m 1000V II Temperature coefficient 0.05 * (specified accuracy) per for temperature < 18 or > 28 Relative humidity 40%~75% (40%~60% when insulation test > 1G) Tester size 19.5 * 15 * 7cm / 7.7 * 5.9 * 2.8in Tester weight 817g / 28.8oz Package size 34 * 26.5 * 10.4cm / 13.4 * 10.4 * 4.1in Package weight 1080g / 38.1oz Package including: 1 * Digital Insulation Tester1 * Pair of Test Leads1 * Pair of Test Clip1 * User Manual (English)
