ANALOG MW HiTESTER 3490 Field measuring instruments 3-range INSULATION & CONTINUITY 3Ω range, 200mA Bright LED OPTION TEST LEAD WITH REMOTE CONTROL SWITCH 9788 Insulation Testing in 3 Easy Steps Flip the Cover, Select Range & Test Check for Live Circuits 2 Check the Battery Status BATT : Hi BATT : Lo BATT : Dead Luminous Scale The LIVE CIRCUIT LED will light up in red whenever the voltage exceeds 20V AC between the LINE and EARTH terminals, and when at least 20V DC is still remaining during the auto discharge. Be well-informed about the condition of your batteries. Green signals that the battery level is sufficiently high, and red warns of low battery power. Replace the batteries before the LED turns completely off.
