误差。偏差。
误差是由于某个热电偶引起,这实际上可消除,(或者)超过了量程,(或者)使用一
个槽形面板(可能是变了形的,引起误差)。
偏差:是当在仪表上调整和温度精度标准调整时(所产生)。当使用不同的热电偶,虽然作了调整,(还是可能会产生偏差)。
较大输入:60V的直流或交流有效值24V,在输入引线或任何输入和接地之间(的电压)。
Technical
Temperature scale: oC or oF User-Selective.
Resolution: 1oC or 1oF (or 0.1oC or 0.1oF)
User-Selectable
Inputs: One K-type Thermocouple
Measurement Range: -50 ~ 1300oC, (-59 ~ 2000oF)
Meter Operating Range:For Using at 0oC ~ 50oC
Environment(32 ~ 122oF)
Accuracy:(18~28oC ambient)
±(0.3%rdg 1oC)-50 ~ 1000oC
±(0.5%rdg 1oC)1000 ~ 1300oC
±(0.3%rdg 2oF)-58 ~ 2000oC
The accuracy specification does not include
type D thermocouple probe accuracy.
Temperature Coefficient:
0.1 times the applicable accuracy specification per
oC from 0oC to 18oC to 50oC
Error Offset:Errors contributed by one particular thermocouple may be practically eliminated, over a limited measurement range, using a recessed front panel OFFSET adjust on the meter and an accurate temperature standard when making the adjustment. Although making the adjustment may increase measurement errors for using different themocouples
