P-63 sound velocity at 20°C
can be used to enter the known velocity, at 20°C, of sound in a particular
gas or vapour or to view the resultant velocity of an empty calibration
(P-61), normalized to 20°C. (F=344.1)
the units of velocity are assumed to be:
meters/sec if P-1= 1 (meters)
2 (centimeters)
feet/sec if P-1= 3 (feet)
4 (inches)
P-64 velocity at P-65
can be used to enter the known velocity, at the temperature of P-65, of
sound in a particular gas or vapour or to view the resultant velocity of an
empty calibration, at the temperature of P-65. (F=344.1)
the units of velocity are assumed to be:
meters/sec if P-1 = 1 (meters)
2 (centimeters)
feet/sec if P-1 = 3 (feet)
4 (inches)
P-65 air temperature in °C, as measured by temperature sensor or preset
transducer operating temperature, if sensor is not used, enter temperature
required in °C (F=20C)
P-66 maximum air temperature in °C
records max. temp. measured by
temperature sensor. Press then to reset (F=-99C)
P-67 minimum air temperature in °C
records the min. air temp. measured by temperature sensor. Press
then to reset (F=150C)
