OFF: Temperature compensation disabled, speed of sound equal to setting of parameter P 07 1: Water-like liquid (parabolic temperature dependence) 2: Other liquid (linear temperature dependence) 6.36 Parameter P 61: Speed of sound at apex The following parameter applies only to water-like liquids: parameter P 60 = 1. 0250 ... 8000: Speed of sound at apex in [m/s] It may happen that the speed of sound is at its maximum at 20°C. The speed of sound in parameter (P 07) always relates to a temperature of 20°C. In such a case simply enter a second pair of values for speed of sound and temperature at P 61 and P 62 even if that is not the maximum speed of sound. The SONOMETER 30 automatically detects it and selects the appropriate instruction for calculation. 6.37 Parameter P 62: Temperature at apex The following parameter applies only to water-like liquids: parameter P 60 = 1. -50 ° ... 150 °: Temperature at apex of characteristic in [°C] 6.38 Parameter P 63: Linear drift of speed of sound Other liquids This parameter applies to all liquids that are unlike water: parameter P 60 = 2. -9.990 ... 9.999: Drift of the speed of sound in [m/s per K] Page 46
