point and full range point. The zero calibration requires the pressure
transmitter to accept an accurate minimum range pressure that the user
wishes to set, and then perform the calibration; full range point
calibration requires the pressure transmitter to accept an accurate
maximum range pressure that the user wishes to set, and then perform
the calibration.
Transmitter current calibration: it is divided into two parts: 4mA
calibration and 20mA calibration. There will be a set value and a
measured value in the calibration interface. The set value is the current
value that is intended to control the output of the pressure transmitter,
and the measured value is the actual current value measured by the
calibrator. If the actual current value is not equal to the current value of
the calibration point, it is necessary to change the set value until the
actual current value is equal to the current value of the calibration point.
At this moment, the calibration is finished.
Read/modify damping: used to modify the measured damping time
of the pressure transmitter. The unit is second.
Conversion function: used to set the conversion relationship
between pressure measured by pressure transmitter and time output
current. It is divided into linear or square root functions.
8 Saving the Verified Data
This pressure calibrator has convenient verified data saving
function, which saves users from the trouble of manually recording
verified data when verifying various types of pressure transmitters, and
stores up to 30 files *110 data. The operation process can be divided into
three steps: (1) creating verified data document; (2) verifying and saving
by point; (3) the verification is completed. After that, the document can
be read through the upper computer software.
