Measurement procedure. True RMS power measurements will be taken at the light switch that energizes the circuit containing only the sampled fixtures.
Measurement procedure. The frequency characteristics of the sound shall be measured together with an input signal to the external sound generation system corresponding to the reference vehicle speed. The sound output of the system shall be measured as follows: Record at least 5 seconds of the sound at a constant vehicle speed. Using a Xxxxxxx window, calculate the autopower of the signal with a frequency resolution of at least 1 Hz using at least 66.6% overlapp averages from the 5 second time signal The frequencies, fi, speed, of the external sound generation system signal shall be measured and recorded. The corresponding vehicle speeds, fi,speed and fi,ref shall be measured and recorded. Calculate del_f, the frequency shift of the external sound generation system signal according to equation (1): del_f = {[(fi,speed - fi,ref)/(vtest – vref)]/fi,ref} · 100 (1) where fi,speed is the frequency at a given speed value; fi,ref is the frequency at the reference speed value; vtest is the vehicle velocity, actual or simulated, corresponding to the frequency fi,speed; vref is the vehicle velocity, actual or simulated, corresponding to the frequency fi,ref; This equation is only valid when the actual vehicle speed, vtest, is higher than the reference vehicle speed, vref. Results shall be reported using Table 3. Table 0A3 — Vehicle speed for measurement to determine frequency shift Target speed Actual Speed (km/h) Frequency, fi, speed (Hz) Frequency Shift Reference vehicle speed Not Applicable 10 km/h 15 km/h 20 km/h NOTE The reference speed should be 5 km/h unless other speeds are desired. ISO comment : If we are going to choose the reference speed as 5, need to change sentence: " The reference speed shall be 5 km/h Figure 1a and 1b
Measurement procedure. Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle.
Measurement procedure. To measure time, an ordinary stopwatch and timing to a resolution of one second is sufficient. All power figures are to be recorded in xxxxx (W). Table 38 outlines the steps of the OM test procedure. Service/maintenance modes (including color calibration) generally should not be included in measurements. Any adaptation of the procedure needed to exclude such modes that occur during the test shall be noted. As stated above, all power measurements are to be made in accordance with IEC 62301. Depending on the nature of the mode, IEC 62301 provides for instantaneous power measurements, five-minute accumulated energy measurements, or accumulated energy measurements over periods long enough to properly assess cyclical consumption patterns. Regardless of the method, only power values should be reported. 1 Off Plug the unit into meter. Turn on unit. Wait until unit indicates it is in Ready mode. – 2 Ready Print, copy, or scan a single image. –
Measurement procedure. 3.1. Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle.

Measurement procedure. (a) Locate a 35 mm or larger format still camera, video camera, or digital equivalent such that the centre of the camera's image plane is located at Mr and the camera lens is directed at the centre of the display's rear- view image.
(b) Affix a ruler at the base of the rear-view image in an orientation perpendicular with a test object cylinder centreline. If the vehicle head restraints obstruct the camera's view of the display, they may be adjusted or removed.
(c) Photograph the image of the visual display with the ruler included in the frame and the rear-view image displayed.
Measurement procedure. The solar heat gain profiler will be placed across different areas of the measurement sample and 10-second averages will be taken. The results will be documented using photographs.
Measurement procedure. 3.1. Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle.
3.2. Separate values of Q shall be logged over the Part One and Part Two of the cycle."

Measurement procedure. 1. Sellers shall provide and install the Measurement Equipment, at its own expense, at a point the Delivery Point or downstream of the Delivery Point for establishing the volume of the Sales Gas that shall pass through the Delivery Point during the Day
Measurement procedure. To confirm that the harmonic voltage and current distortion is within specified limits, UtiliCorp Networks Canada will perform measurements at the customer's supply facilities. Where practical, the measurements will be taken from the POI. (The measurements may be taken elsewhere and calculated to the POI.) The measurements will be performed in such a manner that the harmonic voltage, current, and power flow up to the 50" harmonic is determined. These measurements shall be the basis for mitigation of problems caused by harmonic distortion.
