After jumper is opened transducer address changes to 9Fh
Format of data
Transducer uses data format „Engineering units“, i.e. fixed decimal point. Temperature is
displayed with 2 digits behind decimal point, second digit behind decimal point is always zero.
General writing:
„
>±xxx.x0 cr
“
Examples:
>-050.20

Error States of the transmitter
Transmitter continuously checks its state during operation. In case error is found LCD displays
corresponding error code:
Error 0
First line displays „Err0“.
CRC check sum Error of stored setting in transmitter memory. This error appears if writing
procedure to transmitter memory was not correct, if writing to other address than allowed,
optionally if damage of calibration data appeared. At this state transmitter does not measure and
calculate values. It is an serious error, contact the distributor of the instrument to fix.
Error 1
Measured value is over upper limit of allowed full scale range. There is a reading „Err1“ on LCD
display. Value read from the transmitter is +999,9.
This state appears in case of:
•
Measured temperature is higher than approximately 600°C (i.e. high non-measurable
resistance of temperature sensor, probably opened circuit).
Check connection of measuring sensor.
Error 2
There is a reading „Err2“ on LCD display. Measured value is below lower limit of allowed full
scale range. Value read from the transmitter is -999,9.
This state appears in case of:
•
Measured temperature is lower than approximately -210°C (i.e. low resistance of
temperature sensor, probably short circuit).
Check connection of measuring sensor.
Error 3
There is a reading „Err3“ on LCD display upper line.
Error of internal A/D converter appeared (converter does not respond, probably damage of A/D
converter). No measurement and calculations of values are proceed. It is a serious error, contact the
distributor of the instrument.
