The environmental condition of different locations will be different and based on the shallowness of water, underwater habitat, water temperature and distance from the explosion, etc., the calibration of the device will change but for the primary test condition the whole system will have a fixed sets of parameter and only the gain of the pre-amplifier will vary (motherboard), and this method of calibration will be put on to the trial at the actual field test. So, to achieve this single variable-based calibration process, the following steps were taken:

1. From the function generator, the amplitude of the test signal (sinusoidal wave) has been set to 100mVp
2. Set the Pre-Amplifier output to 1V
3. Set all the amplifiers (only for ASA) output to 2V
4. Set all the LLC’s threshold voltage to 600mV (Positive level detector, threshold value)
