Terminal Description Using Thermocouple (TC)  

The calibrator supports 8 types of standard thermocouples, including J, K, T, E, R, S, B, N.

Lower table summarizes the ranges and characteristics of the supported thermocouples:

Graduation	Positive lead material	Positive wire (H) color		Negative lead material	Specified span°C
		ANSI*	IEC**
E	Chrome-nickel	Mauve	Purple	Constantan	-200~950
N	Nickel-chrome-silicon	Orange	Pink	Nickel-silicon-magnesium	-200~1300
J	Iron	White	Black	Constantan	-200~1200
K	Chrome-nickel	Yellow	Green	Alumel	-200~1370
T	Copper	Blue	Brown	Constantan	-200~400
B	Platinum (30% rhodium)	Grey		Platinum (6% rhodium)	600~1800
R	Platinum (13% rhodium)	Black	Orange	Platinum	-20~1750
S	Platinum (10% rhodium)	Black	Orange	Platinum	-20~1750
* Negative conductor (L) regulated as American National Standard (ANSI) is always red. *Negative conductor (L) regulated as International Electro-technical Commission (L) is always white.

Automatic compensation  

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.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  key, the  sign is replaced for current automatic cold end temperature compensation value as . The value  continue to display for 2s and then automatically return to the  sign. 

Factory Reset  

Factory reset consists of the following items:

1)  The working status recovers to the voltage measurement.

2)   Automatic shutdown time is reset to be 30 min, which is effective.

3)    LCD backlight brightness is set to be 60%.

4)   Output span is recovered to be factory default.

Start the calibrator and press  until the buzzer works, and the recovery of factory default will enter working mode when the recovery is completed.
