East Tester HART 475 User Manual page 10

Click the following operation to enter the unit function of setting pivot variables:
(4 detailed Settings) → (2 signal conditions) → (1 user range unit)
7.2 set the upper limit of the range
The upper limit of the range can be set by following:
(4 detailed Settings) → (2 signal conditions) → (2 user range upper limit)
7.3 set the lower limit of the range
The lower limit function of the set range can be entered by following operations:
(4 detailed Settings) → (2 signal conditions) → (3 lower limit of user range)
7.4 setting damping
Press the following operation to enter the setting damping function:
(4 detailed Settings) → (2 signal conditions) → (4 damping)
7.5 output current fine-tuning
Press the following operation to enter the output current fine-tuning function:
(2 diagnosis and maintenance) → (3 calibration) → (1 output fine-tuning)
Note: the output current fine-tuning function can only be performed when HART
instrument leaves the factory and is tested periodically.The use of this function
requires the authorization of the HART instrument owner, otherwise the output error
of HART instrument may be increased.
7.6 pivot variable zeroing
Click the following operation to enter the pivot variable zeroing function :(some
instruments do not have this function)
(2 diagnosis and maintenance) → (3 calibration) → (3 sensor fine-tuning) → (1
zero calibration)
Note: the zero setting function of the principal variable can correct the zero
deviation of the instrument output caused by the installation position, which can
only be carried out when the HART instrument is first installed and the instrument
cycle is verified.The use of this function requires the authorization of the HART
instrument owner, otherwise the output error of HART instrument may be
increased.
