THERMOCOUPLE-ACCURACY TABLES

The following tables are provided to easily ascertain the maximum error allowed for the
thermocouple types supported. They apply when either sourcing or measuring temperature with
thermocouple wires. A 95% confidence level (k = 2) is assumed. The errors were derived using
the RSS (root of the sum of the squares) of all the applicable sources for error. These errors
include:
1.
Cold-junction compensation (if used without CJC, errors are reduced).
Variation of the environmental temperature by ±5°C from calibration temperature. If
2.
a better temperature environment is maintained, errors will be reduced.
3.
Noise, 1 µV peak in a "0.1 Hz to 10 Hz" bandwidth.
4.
Accuracy, as listed on page
Uncertainty limits (k = 2) of Ectron's temperature measurement system, ±0.01°C.
5.
Conformity, ±0.4 µV.
6.
LCD with adjustable contrast and backlight, which can be
turned off, on, or timed out with settings of 30 seconds,
one minute, two minutes, or five minutes.
USB included; Ethernet, GPIB, and RS-232 optional.
Carrying case.
Calibration kit consisting of a terminal cover, shorting bar,
low-thermal cable, calibrated Type T thermocouple, and
calibrated Type E thermocouple.
