6.4 - Use of the functions

6.4.1 - Reading the external probes (only TC version)

It is possible to display one or two probes tied to the EXT and REF inputs.

The following probes can be connected:

1. THERMOCOUPLES TYPE J, K, R, S, N, E with automatic compensation

of the terminal clamp temperature.

2. THERMAL RESISTANCE Pt 100 to 2, 3 or 4 wires.

 Connect the probe’s wires to the clamps as it is indicated in the figures.

 Thermocouple – connect the wires to the clamps 2-4 to make

attention to the polarity; connect the clamps 1-3 as indicated.

Reference to Fig. 7-A

 Pt100 to 4 wires – connect the clamps 1-2-3-4 as indicated in Fig.

7-B

 Pt100 to 3 wires – connect the wires to clamps 1-2-3; connect the

clamps 3-4. Reference to Fig. 7-C

 Pt100 to 2 wires – connect the wires to clamps 2-4; connect the

clamps 1-2 & 3-4. In case of two wires connections remembers to

us shortest wires possible. Refer to Fig. 7-D

 In order to read the external probe’s temperature press the F key up to

read SENSOR, select EXT or REF or EXT + REF then confirm with E

key. Press the and F keys together to jump to the second level of the

parameters, press F to read EXT SENSOR TYPE and REF SENSOR

TYPE and press the  and the keys to select the probe; the

temperature will be displayed on the at the bottom of the display.

 Press the and F keys together to jump to the first level again , the

temperature will be indicated on the bottom of the display.

 In order to read in the '°F' way, refer to the procedure explained in

paragraph 10.1 till Units°C/°F/K; the conversion of the new scale will be

carried out at once.

NOTE: The calibrator always thermally adjusts with the control probe

situated inside the block.

MESSAGE OF ERROR OF THE EXTERNAL PROBES DISPLAY

The display in the case of connection or configuration errors indicates:

EST SENSOR FAIL : wrong connection or configuration of the EXT probe

REF SENSOR FAIL: wrong connection or configuration of the REF probe

SENSORS FAIL: wrong connection or configuration of the REF and EXT probes
