The EUT was then measured for all the radiated emissions in the frequency range of 30MHz 1GHz. Measurements were made using the spectrum analyzer and receiver using the appropriate antennas, amplifiers, attenuators, and filters. The required Quasi-Peak CISPR bandwidth shall be 120 khz for the range 30 1000 MHz. A 1 MHz Resolution Bandwidth (RBW, CISPR Band E) shall be used and a 10 Hz Video Bandwidth (VBW). The ANSI C63.4:2014 requirement for the placement of RF Absorber on the turntable Ground Plane shall be satisfied. Emissions in both horizontal and vertical polarizations were measured while rotating the Equipment Under Test (EUT) on the turntable to maximize signal strength. In the case of high ambient noises, the measurements are performed at a closer distance and the limit is adjusted per the equation below. The result is added or subtracted to the required emission level to ensure compliance at the new distance. 20 log ( D1 D2 ) ; Where D1 = Current Distance D2 = Required Distance Report Number: E10858-1702_Kron_Rev1.0 Page 14 of 51

Modifications: No modification was required to comply for this test. Result: The EUT complies with the applicable standard. Report Number: E10858-1702_Kron_Rev1.0 Page 15 of 51

Section IV: IMMUNITY TESTING Performance Criteria as per standards EN 55024:2010/AC:2011 Criterion A Criterion B Criterion C The equipment shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended. The equipment shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is however allowed. No change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended. EXAMPLE 1: A data transfer is controlled/checked by parity check or by other means. In the case of malfunctioning such as caused by a lightning strike, the data transfer will be repeated automatically. The reduced data transfer rate at this time is acceptable. EXAMPLE 2: During testing, an analogue function value may deviate. After the test, the deviation vanishes. EXAMPLE 3: In the case of a monitor used only for man-machine monitoring, it is acceptable that some degradation takes place for a short time, such as flashes during the burst application. EXAMPLE 4: An intended change of the operating state is allowed if self-recoverable. Temporary loss of function is allowed, provided the function is self-recoverable or can be restored by the operation of the controls. EXAMPLE 1: In the case of an interruption in the mains longer than the specified buffer time, the power supply unit of the equipment is switched off. The switch-on may be automatic or carried out by the operator. EXAMPLE 2: After a programme interruption caused by a disturbance, the processor functions of the equipment stops at a defined position and is not left in a crashed state. The operator s decision prompts may be necessary. EXAMPLE 3: The test results in an opening of an over-current protection device that is replaced or reset by the operator.

4.1 Electrostatic Discharge Immunity Testing Date Performed: April 19, 2017 Test Standard: EN 55024:2010/AC:2011 Test Method: IEC 61000-4-2:2008 Minimum Criteria: Criteria B Method of Measurement: When the equipment is subjected to air discharge or contact discharge of the selected severity level, the equipment must meet the minimum performance criteria described above. Each operator accessible connector and control is discharged 10 times without a system failure. Longer time between discharges may be required in order to be able to distinguish between a response caused by a single discharge and a response caused by a number of discharges. IEC 61000-4-2: 8.3.2 - Indirect application of the discharge. Discharges to objects placed or installed near the EUT are simulated by applying the discharges of the ESD generator to a coupling plane, in the contact discharge mode. Horizontal coupling plane - at least 10 single discharges (in the most sensitive polarity) is applied to the horizontal coupling plane, at points on each side of the EUT. The ESD generator is positioned vertically at a distance of 0.1 m from the EUT, with the discharge electrode touching the coupling plane. Vertical coupling plane - at least 10 single discharges (in the most sensitive polarity) is applied to the centre of one vertical edge of the coupling plane. The coupling plane, of dimensions 0.5 m x 0.5m, is placed parallel to, and positioned at a distance of 0.1 m from, the EUT. Discharges shall be applied to the coupling plane, with sufficient different positions such that the four faces of the EUT are completely illuminated.
