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 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
instrument to fix.
Error 1
Measured value is over upper limit of allowed full scale range. There is a reading „Err1“ on LCD
display. This state appears if measured temperature is higher than approximately 600°C (i.e. high
non-measurable resistance of temperature sensor, probably opened circuit).
Error 2
There is a reading „Err2“ on LCD display. Measured value is below lower limit of allowed full
scale range. This state appears if measured temperature is lower than approximately -210°C (i.e.
low resistance of temperature sensor, probably short circuit).
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 measurements proceed. It is a serious error, contact distributor of the instrument.
