Lamp in the top part with high-brightness, low-consumption LEDs, for use in dark places. Lamp use is independent of the detection system. Voltage present indicator using multiple high-brightness red LEDs over 360° and buzzer-type intermittent acoustic signal. Absence of voltage indicator with multiple high-brightness green LEDs over 360º. Low battery indication by orange LED. Self-checking system for the full circuit by pressing the test button. Stops operating when the battery is low.
Working temperature range: -25°C to +55°C. Auto-start-up with voltage presence. Auto-power-down to standby after two minutes with absence of voltage. Power consumption is less than 1 µA in this mode.
Coupling to stick using Universal head. 2xAA high-capacity and high-durability batteries included.
