1. Operation panel description:
• The transmitter board provides a three-button and Led display man-machine
interface to operate all transmitter Settings and calibration parameters.
• Key functions are multiplexed. A down key is a shift key when the input data
is shifted.
2. Clear the zero deviation:
• Given zero standard pressure, long press increase button for 10 seconds to
calibrate full degree.
• Given full standard pressure, hold down the reduce button for 10 seconds to
calibrate zero.
This operation is a shortcut provided to customers, generally not end users do not
enter this function to prevent calibration data damage.
3. Menu operation, as shown below:
Calibration menu is the transmitter calibration way for factory calibration and
general technical supervision department, general users do not enter the setting of
any data, non-professionals modify any data may lead to the transmitter
completely
unable to work.
Circuit board through the panel of the three keys to achieve all the parameters
input and calibration data Settings, collection. The circuit board on the meter
setting and input to take a variety of optimization measures to improve customer
operation speed:
• The decrease key and increase key of the meter have variable speed function
• For the menu that needs to be modified by a large number, the menu that
needs to continuously input data adopts the shift mode, and the menu that needs
to continuously input data adopts the incremental mode
• The meter will stop analog output in the set state, so if the user does not
operate the meter within 3 minutes, it will automatically exit to the measurement
state
• The shift input has a flashing prompt function
