Local Adjustment
For configuration via local adjustment to be possible:
•
The write protection jumper must be disabled;
• Local adjustment jumper must be enabled.
See Figure 1.4 for the positions of the Local Adjustment and Write Protection jumpers on the main
electronic board.
The transmitter has, under the identification plate, two holes that allow the placement of the magnetic
tool for the Local Adjustment. See Figure 2.8.
Figure 2.8 – Local Adjustment
The holes are marked with
Z
(Zero) and
S
(Span) and henceforth will be designated by only (
Z
) and (
S
),
respectively.
The movement through the functions and their branches works as follows:
• By inserting the handle of the magnetic tool in (
Z
), the transmitter leaves the normal
measurement state to the transmitter configuration state. The transmitter software
automatically starts indicating the available functions on the display, cyclically;
• Leave the key at ( Z ) to cycle through all available configuration options;
• Once the display shows the desired option, change the key to ( S ) to select the option and
navigate within the branch of the selected option. Removing the key will make the equipment
save the changes made (in case of change).
The availble options for local adjustment of
