Images are for illustration purposes only. E&OE Overview The K3007 has three test voltage ranges: 250V, 500V and 1000V and is equipped with a unique bargraph display that illustrates to the user that the insulation under test meets the minimum voltage required by the regulations.An advanced feature included in both models is Auto Null mode, this unique function subtracts the test lead resistance during continuity tests, ensuring repeatable accuracy.The top of the range K3007 is equipped with Trac-Lok circuits that improve battery life considerably, thus saving the user money.Another great feature is the EL Backlight on the display which enables readings to be taken in dimly lit areas.The K3007IS Intrinsically Safe option is available on request Features Three test ranges 250V-500V-1000VAuto null functionIntrinsically safe version available on requestMain bargraph indication of insulation resistance, sub bargraph indicates output voltageDisplays the value of external AC voltage along with flashing symbol and buzzerLock Down Test Button for continuous use1mA output current on insulation test200mA short circuit on continuity rangeTrac-Lok mode to extend battery life by up to 400%EL Backlight for dimly lit areasK3007IS is an Intrinsically Safe version Downloads Datasheet - MAJ K3007 PDF File 1.23 MB
