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. | |||||
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 ResetFactory 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.
