• Regulatory compliance
• Detailed report generation

The test bench is intended for measuring the open-circuit voltage, discharge current, and for calculating the impulse energy of an electroshock device when operating with a load.

The test bench consists of: an oscilloscope, a high-voltage voltmeter (or a high-voltage measuring divider), an ammeter (or a current sensor), and a load resistor.

1. Oscilloscope

The oscilloscope provides measurement and recording of the impulse waveform:

• open-circuit voltage measurement (no-load mode) via a high-voltage measuring probe/divider;
• ADC sampling rate: not less than 120 MSa/s;
• permissible measurement error: not more than 5% (when using standard/certified probes);
• capability to accurately display the waveform and to calculate the maximum value and the integral;
• capability to calculate power (W) and delivered energy (J) when operating with a 1,000 Ω load.

2. Voltmeter / High-voltage measuring chain

•  provides voltage measurement up to at least 100 kV (in open-circuit mode), taking into account the impulse nature of the signal;
• it is acceptable to use, instead of a separate voltmeter, a high-voltage measuring divider/probe that scales the signal down to a safe level for the oscilloscope.

3. Ammeter / Current sensor

• provides discharge current measurement when operating with a 1,000 Ω load;
• the measurement range shall match the expected current of the electroshock device samples under test, but not less than 10 mA.

4. Load resistor

•  provides a load of not less than 1,000 Ω;
• rated for impulse operation (permissible impulse energy/voltage according to the test modes);
• the design ensures electrical strength, required insulation distances, and protection against surface leakage currents.
