see table below.
Cause What to do
E-01
EEP.E
Error in EEPROM cell programming. Call Assistance.
E-02
SYS.E
Cold junction sensor fault or room
temperature outside of allowed
limits.
Call Assistance.
E-03
MEM.E
Error in Memory card programming. Repeat Memory card programming.
E-04
EEP.E
Incorrect con guration data.
Possible loss of calibration values.
Check if the con guration parame-
ters are correct.
E-05
prb.
Thermocouple open or temperature
outside of limits.
Check the connection with the
sensors and their integrity.
E-08
SYS.E
Missing calibration data. Call Assistance.
