First entered the thermocouple measurement mode, the default of the cold end
temperature compensation is automatic compensation reading as shown in
Figure 4.1.1-1.The sign represents that the current cold end
temperature compensation is automatic compensation. If you need further view
current automatic cold end temperature compensation value,you have to
operation key. Reading as shown in Figure 4.1.1-1,after press

4.2 Using Resistance Thermometer
Detector (RTD)
The calibrator accepts Pt100, Pt1000, Cu50 and Cu100, etc. The calibrator
accepts RTD measurements inputs in two-, three-, or four-wire connections,
with the three-wire connection the most common. A four-wire configuration
provides the highest measurement precision, and two-wire provides the lowest
measurement precision.
To measure temperature using an RTD input, proceed as follows:
1. Press to select mode.
2. Press for the RTD display. Then the screen will display as shown in
Figure 4.2-1. If desired, continue pressing this key to select the desired
RTD type.
3. Connect RTD to the corresponding port according to the connecting type
of ‘resistance measurement’.
