On receiving command the transducer replies by sending an ASCII string containing the
firmware version, the reference date and the serial number.
14.3.6. COMMAND “T”
Command “T” allows transducer calibration: it memorises what the transducer has
measured, when the cursor is positioned in correspondence to the ZERO or FULL SCALE
references, matching the measurement to the numerical references set with the “L”
commands.
Example 1:
@ 0 T0Z <cr>
Measures and memorises the position of cursor 0 at the ZERO point.
Example 2:
@ 0 T0F <cr>
Measures and memorises the position of cursor 0 at the FULL SCALE point.
Example 3:
@ 0 T1Z <cr>
Measures and memorises the position of cursor 1 at the ZERO point.
Example 4:
@ 0 T1F <cr>
Measures and memorises the position of cursor 1 at the FULL SCALE point
IMPORTANT NOTE : after memorising the new positions, in order for them to have effect,
it is necessary to switch the transducer off and then switch it on again. In this way the
internal coefficients can be recalculated.
To ensure correct transducer operation it is necessary to calibrate the transducer so that
the correlation summarised here can be observed:
ZERO FULL SCALE
Set reference Memorise
measurement
Set reference Memorise
measurement
Cursor 0
@0L0Lxxxxxx @0T0Z @0L0Hxxxxxx @0T0F
Cursor 1
@0L1Lxxxxxx @0T1Z @0L1Hxxxxxx @0T1F
Note 1: “xxxxxx” refers to the 5-figure subject to be sent to the transducer with relative
command.
Note 2: Each command sent to the transducer must end with <cr> (Carriage Return, 0x0D)
14.3.7. COMMAND “X”
Command “X” allows to read the memory contents of the EEPROM programming.
In this memory the parameters for transducer configuration are permanently stored. These
are modified and memorised with the aforementioned commands. Table 4 indicates the
significance and location of the parameters.
