Parameter Description
P650 Offset Calibration
Typically used to calibrate the ultrasonic measurement, and its associated
outputs, to a known value.
• fill the tank as much as permissible, without going into the near blanking.
• monitor P650 until a stable reading is obtained.
• Press
(to access change function).
• scroll the value to the actual level, space or distance respective to the mode
of measurement (P001).
• Press
(to validate entry). The MiniRanger Plus calculates the
measurement offset to be applied to the reading.
P651 Sound Velocity Calibration
Provides sound velocity compensation on an empty tank. This is typically
required on an application where the atmosphere in the tank is a
homogenous gas or vapour other than air.
• empty the tank as much as permissible. Leave filled with normal vapour and
normal operating temperature.
• monitor P651 until a stable reading is obtained.
• Press
(to access change function).
• scroll value to the actual level, space or distance respective to the mode of
measurement (P001).
• Press
(to validate entry). The MiniRanger Plus calculates the new sound
velocity for measurement correction.
P661 Temp Fixed
For use with ST-25 Ultrason® transducers. As these transducers do not
have an integral temperature sensor, a nominal value representing the
ambient temperature of the transducer must be entered.
If the temperature between the transducer and the target varies, enter the
average temperature.
entry:
–50 to 150 °C
P664 Temperature
View the temperature in °C as registered by the transducer's integral
temperature sensor (Echomax series). If a non temperature sensing
transducer is being used, the fixed temperature (P661) is displayed.
values:
-50 to 150
