7. Error States of the device
Device continuously checks its state during operation. In case error is found LCD displays
corresponding error code:
Error 0
- first line of LCD displays „Err0“. Check sum error of stored setting inside device’s
memory. This error appears if incorrect writing procedure to device’s memory occurred or if
damage of calibration data appeared. At this state device does not measure and calculate values. It
is a serious error, contact distributor of the device to fix.
Error 1 -
measured or calculated value except in pressure is over upper limit of allowed full scale
range. There is a reading „Err1“ on LCD display. Value read from the device 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).
Relative humidity is higher than 100%, i.e. damaged humidity sensor, or humidity calculation
of humidity is not possible (due to error during temperature measurement).
Computed value – calculation of the value is not possible (error during measurement of
temperature or relative humidity or value is over range).
The value of pr999.9 hPa is correct value!
Error 2 -
there is a reading „Err2“ on LCD display. Measured or calculated value is below lower
limit of allowed full scale range. Value read from the device 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).
Relative humidity is lower than 0%, i.e. damaged sensor for measurement of relative humidity,
or calculation of humidity is not possible (due to error during temperature measurement).
Measured pressure value
with added correction for altitude
is outside of range from 300 hPa
to 1350 hPa (from 4.351 PSI to 19.580 PSI) or the pressure sensor is damaged. Please check
setting of pressure correction for altitude with User’s software.
Computed value – calculation of computed value is not possible (error during measurement
of temperature or relative humidity
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). This error does NOT
affect pressure measurement. Rest values are NOT measured. It is a serious error, contact
distributor of the device.
Error 4 -
there is a reading „Err4“ on LCD display. It is internal device error during pressure sensor
initialization. Under this condition device does NOT measure atmospheric pressure. Value read
from device is -999.9. Pressure sensor is probably damaged. It is a serious error, contact distributor
of the device.
Error 5, 6 -
there is problem with assigned value to output relay, there is some wrong setting
(mismatch). This error appears if incorrect writing procedure to device’s memory occurred.
Error 9 -
inserted password is not valid, there is shown for short time message “Err9” on LCD
display.
