“Power midgets”

The PocketDetect series provide you with a line of miniaturized, highly specialized and very easily operated voltage detectors.

Parts: PD-01HR and PD-01LM

Equipped with a thorough self test to ensure reliable function, a permanently enabled interface-tester to warn against defect interfaces or residual voltages and a low power long term display mode to ensure secure working each and every PocketDetect delivers uncompromising safety. They can be carried along due to their diminutive dimensions and light weight (e.g. in the optional available belt case).

Application and technique

PocketDetect is a VDS (Voltage Detecting System) according to IEC/EN 61243-5 (DIN VDE 0682 T415). You can choose between HR, MR, LR, LRM or LRP versions. Adapters are not planned yet.

The indication of the interface current is carried out by means of two bright LEDs, which display the conditions voltage absent, residual voltage, voltage present, string part ok and high current respectively. After 60 seconds of operation without user interaction the display switches to low power mode, indicating only the states voltage absent and voltage present. The device shuts down after four hours of operation automatically.

The evaluation of the actual voltage state is accomplished by an rms-value measuring method independent of the applied waveform. Moreover the interface will not be loaded, like it is ordinarily done in this field of scale. By means of the active display no external light source is required for metering, like it is needed for passive LC-displays: you rather deplete torch light batteries than device-batteries.

The integrated self-test ensures unfailing operation. It starts automatically whenever the device is switched on. After pushing the button once the device checks the LEDs, the battery voltage and the correct functioning of electronic measuring circuits and software. When an error is detected you will be notified of fault condition by deterministic flashlight signals and operation is denied.

The power supply is realised by an exchangeable, commercially available lithium coin cell (CR2032) supplying the thrifty microcontroller electronics for many operating hours.
