Chapter 4 Menu and operation
The zero point and coefficient of current
calibration, and the value calculated by the
instrument during current calibration. (Note:
During operation, please do not arbitrarily
change the value here, which will affect the
accuracy of current output)
The zero point and coefficient of
temperature calibration are used to correct
the measurement error of temperature
sensor. (Note: Please do not arbitrarily
change the values here during the
operation, which will affect the temperature
measurement accuracy and level
measurement accuracy)
Sound speed calibration requires a standard
distance measuring instrument. Given a
distance, enter the standard measurement
value into the value in the second row. The
distance in the fourth row displays the
measured value of the instrument. Press
SET key to prompt successful or failed
calibration. (Note: Considering the accuracy
of sound velocity calibration, calibration can
only be carried out when the distance is
greater than 1 meter. In addition, please do
not arbitrarily change the value here during
operation, which will affect the accuracy of
level measurement)
