Vernier Thermocouples have been updated a few times since they first began shipping.<\/p>\n

In September 2016, we changed the calibration from linear to 2nd order polynomial to get better accuracy. These units have model number TCA1816R3 on the label. Logger Pro<\/i> 3.11, Logger Lite 1.9, and LabQuest App 2.7 are the first versions of our software to support this new model.<\/p>\n

Units shipped after September 2016 have the following calibration equations:<\/p>\n

Calibration ‘Thermocouple \u00b0C’:
\n     Equation: 2nd Order Polynomial
\n     y = cx^2 + bx + a
\n     a: -185.19
\n     b: 311.32
\n     c: -1.7873<\/p>\n

Calibration ‘Thermocouple \u00b0C Low’:
\n     Equation: 2nd Order Polynomial
\n     y = cx^2 + bx + a
\n     a: -274.27
\n     b: 640.14
\n     c: -305.66<\/p>\n

Calibration ‘Thermocouple \u00b0C High’:
\n     Equation: 2nd Order Polynomial
\n     y = cx^2 + bx + a
\n     a: -7.7423
\n     b: 195.71
\n     c: 16.904<\/p>\n

Units shipped before September 2016 have the following calibration equations:
\nThermocouple \u00b0C
\n     * Intercept: -196.88
\n     * Slope: 327.360<\/p>\n

Thermocouple \u00b0C Low
\n     * Intercept: -323.956
\n     * Slope: 514.839<\/p>\n

Thermocouple \u00b0C High
\n     * Intercept: -284.075
\n     * Slope: 353.501<\/p>\n

Units were also updated in spring 2004. Previous models had two wires, while the 2004 and newer model has only one wire. Logger Pro<\/i> 3.3 and Logger Lite 1.2 are the first versions of our software to support this model.<\/p>","protected":false},"excerpt":{"rendered":"
