NOTE
Making adjustments is possible only after adjustments have been
unlocked. To unlock the adjustments, press the ADJ button on the
motherboard of the transmitter.
LCP1, LCP2, LCP3
The LCP1 command performs offset adjustment for barometer
module/module P1. The
LCP2 and LCP3 commands do the same for
modules P2 and P3. Use the commands:
- to view current linear/offset adjustments
- to activate or deactivate the linear/offset adjustment function
- to enter new offset or linear offset/gain pressure adjustments to the
transmitter.
NOTE
Each barometer module has its own adjustment commands. You must
enter the linear/offset adjustments for each barometer module
separately.
To enter new offset (1-point) or linear (2-point) adjustments:
1. Enter the command
LCP1 ? (and LCP2 ?, LCP3 ?, if
applicable) to display current pressure adjustments.
2. Write down the current settings if you want to restore the old
values later on.
3. Enter the command
LCP1 OFF (and LCP2 OFF, LCP3 OFF,
if applicable) to deactivate the previous adjustments.
4. Put PTB330 to reference pressure conditions and write down the
reference and measured P
1
(P
2
, P
3
) values for linear offset/gain
adjustment.
