I’m measuring temperature, but the recorder's temperature display is higher than the actual temperature. Can I correct the temperature on the recorder? I don't have the broken line correction option (/CC1).

Yes, by setting the range rating mode to Scale.

For example, with a K thermocouple and measured values with an input span of 0.0°C–100.0°C, to lower all temperatures by 1°C, enter the following settings.

Mode: Scale

Range: TC

Type: K

Span lower limit: 1.0

Span upper limit: 101.0

Scale lower limit: 0.0

Scale upper limit: 100.0

Unit: °C
