P853 Allocation
This parameter indicates which transducer is being used to obtain the
temperature, in the case of the Zenith this can be viewed but cannot be
changed.
OPTION DESCRIPTION
0 = Xducer 1 (Default) Temperature obtained from Xducer 1
1 = Xducer 2 Temperature obtained from Xducer 2
P854 Fixed Temperature
This parameter sets the temperature, in degrees centigrade to be used if
P852 ( Temperature Source ) = 3 . Default = 20 o C.
Velocity
P860 Sound Velocity
This parameter allows for the velocity of sound to be changed according to
the atmosphere the transducer is operating in. By default, the velocity is set
for sound travelling in air at an ambient temperature of 20 degrees
centigrade (at 1bar, atmospheric pressure).
Default = 342.72 m/sec.
P861 Cal. Dist 1
This parameter is used to re-calibrate the speed of sound for Xducer 1
P861 Cal. Dist 1
This parameter is used to re-calibrate the speed of sound for Xducer 2, when
P100 4 (Avg. Level), 5 (Differential Level) or 6 (Volume Average)
To obtain best results calibration should be carried out when the level is as
near empty as possible and when any vapour present has stabilized.
With the material at a steady level, view the value of P861 , which will
indicate the current distance as calculated by Zenith with respect to the
current value of P860. Physically measure the distance from the face of the
transducer to the surface of the material level and enter this value, in
Measurement Units P104 and P860 will be automatically updated to
compensate for any difference between the displayed and entered values.
