1.12 Measuring thermocouples
• Thermocouples accepted
The instrument accepts direct connecon of thermo-
couples type K, J, E, N, L, R, S, B, T and C.
• Temperature ranges and total error
Temperature ranges and total error for each type of thermocouple
are indicated on ‘Table 10’ below.
• Cold juncon compensaon
The thermocouple cold juncon is automacally compensated by
the instrument. The automac compensaon can be disabled from
the conguraon menu.
• Resoluon and units
The instrument resoluon when measuring thermocouples is 1º.
Reading can be congured in ºC (degrees Celsius) or ºF (degrees
Fahrenheit).
• Sensor break detecon
In case of sensor break, the instrument will show ‘h.ovr’ or ‘h.udr’
(see secon 1.28) depending on the broken cable.

• Compensated cable
To correctly measure a thermocouple signal, always use compensat-
ed cable, of the thermocouple used, to connect the instrument and
the thermocouple.
• Response mes
The response me to a signal step is 300 mSeconds, independent of
the signal range selected.
• Terminal 5 ‘mulfuncon’ - External control
Terminal 5 remains congured as ‘EK’ external control funcon. See
secon 1.9 for a list of available funcons.
• Start-up, connecons and jumpers
For instrument start-up follow the steps listed at secon 1.7. Signal
connecons are indicated at secon 1.5. Locaon for internal jump-
ers is indicated at secon 1.9.
