Handling –

1. Drop Test – The sensor assembly shall withstand a free fall of 1.5 meters (+0.1 m / -0 m) from each of three orthogonal axes, shown in Figure 4 below, on to a smoothhorizontal concrete surface.

Acceptance Criteria: Sensors shall meet the requirements of section2.2.2.  In addition, the sensors shall show no signs of cracking, damage or other physical degradation

2. Intermediate Signal Characterization – Dynamically measures the high and lowcurrent output after individual test environments, at temperature TN.  Testing shall be performed using the circuit in Figure 2 and fixturing which mimics the dimensions and materials used in theapplication, as described at the time of testing.  Measure and record the minimum and maximum current output (via the load resistor, Rload), and duty cycle for each sensor. Perform measurements at AGMAX andthe maximum and minimum frequency.

Acceptance Criteria: Sensors must perform within the applicable parameters outlined in section 1.2.
