CALYS 1500
B.2.8
Measurement by Thermocouple (Temperature)
Display the MEASUREMENT MENU dialogue box:
Select the Tc measurement function, then the appropriate "type of thermocouple" using the function and
navigation keys.
Select the display unit
Select the type of cold junction (CJC) used. Enter the temperature of the cold junction in the case of a
programmed cold junction.
Confirm with ENTER.
The thermocouples available are: K, T, J, E, N, U, L, S, R, B, C, PL, Mo, NiMo/NiCo.
After a significant thermal shock, it is recommended that the unit is left for the temperature to stabilize in order to
use the internal cold junction (CJC) with maximum accuracy.
B.2.9
Thermistor Measurement (Temperature)
Display MEASUREMENT MENU dialogue box:
Select Thermistor "measurement function, then select Auto, 2-Wire, 3-Wire or 4-Wire connection with the
function and navigation keys.
Enter coefficients corresponding to thermistor Coeff. A, Coeff. B and Coeff. C.
Confirm with ENTER.
Wiring diagram is automatically detected by the calibrator. The CALYS 1500 displays an icon showing the connection
used to carry out measurement (
On channel 1, thermistors can be measured over a 0-50 KOhm range, while measurement is limited to 0-3.6 KOhm on
channel 2.
To avoid errors when measuring with 3 wires, the following is recommended:
Measure using conductors with same length, same diameter and same type.
Clean connections to avoid development of spurious electromotive force (emf).
Use Y-shaped lugs to reduce connector resistance.
