To zero balance the beam balance scale, place the main and fractional sliding beam weights directly over their respective zeros, and move the adjustable weight until the beam is in zero balance. Then push the weight back towards the zero position until too much weight has been removed. Move the weights on the fractional beam back and forth until the indicator is centered. Weight for length above 95th percentile. Weight for length below the 5th percentile.
Growth curve is flat over period of time.
Weight for age at or above the 95th percentile. This indice is only useful when serial measurements are taken over time. Weight for age at or below the 5th percentile. This indice is only useful when serial measurements are taken over time.
