A Quick Review Of Its Inside Working - koban KVD-01-33 Mode D'emploi

4. A quick overview of its inside working
● Arming
The detector has a combined manual and a self arming mode.
● Manual Arming Mode
The ARMING/TEST button is mounted on the front viewing face of
the detector (the front viewing face of the detector has the buzzer,
mounting stud (which has the attachment adaptor to the link stick),
arming/test button and the lights It's also called the Facia).
twice per second and the loud Buzzer (audible warning device)
sounds also twice per second.
This is the display for voltage PRESENT.
Pressing the button, activate an internal oscillator, and couple it
to the input of the sensing circuitry, tough, simulating an external
voltage.
When the button is released the display changes to the High
This is the display for voltage NOT PRESENT and battery OK. The
detector is then armed and ready for use. This armed condition
lasts for about 3 minutes.
Arming the detector also functionally checks the internal circuitry
but does not check the input protections or contact electrode
extension nor the internal sensing capacitor for an open circuit
● Self Arming Mode
In this mode of operation the detector automatically switches on
when a High Voltage A.C. is applied to the contact electrode.
● Indicating lights
Two sets of High Bright Leds, one is Green, one is Red are
available.
One is green for voltage NOT PRESENT and Battery OK and the
other is red for voltage PRESENT.
