Personal Safety Voltage Detector
The 288SVD consists of an internal pickup AC sensor plate, a test (oscillator) and diagnostic circuit, an adjustable threshold comparator, a sound annunciator (buzzer), a visual indicator (super high bright led) and a 9V battery, all enclosed into the robust "beeper" style case. The enclosure has a built-in clip to be able to be attached on the outer garments/external clothing or belt.The 288SVD detects AC voltages using it's internal AC sensor plate. The AC sensor plate picks up part of the radiated electric field in volts per meter (V/M).
The electric field is amplified and processed by the internal circuitry and once the processed signal is above the threshold, triggers the input of an integrated circuit, which start the oscillator for the buzzer and LED. The Buzzer beeps and LED lit intermittently at a rate of 2 beeps/flash per second. The "self-test" diagnostic is actioned by depressing simultaneously both push button on the front panel. The battery monitoring is always ON. Please see the priority of alert on the front panel. It is recommended that when the 288SVD is used in HV yards of mixed voltages: In the presence of mixed voltages, it could become difficult to determine exactly which source has been detected or which source created the alert. Always treat all sources as LIVE.
