How to measure the temperature of the LED Line

Tc point to measure the LED Line 1ft 3R temperature

Tc point to measure the LED Line 2ft 1R temperature

The Tc values are specified at the Tc point, which is indicated on the LED

Line. The temperature can be measured via thermocouples that are firmly

glued to the upper surface of the LED Line.

For LED Line 1R and 2R also the onboard NTC can be used for

measurements during development. For all measurements the

temperature must be stable before any reliable data can be obtained

(between 0.5 and 3 hours).
