I’m inputting a signal of 0–150°C/1–5 V from a transformer to the µR10000. The temperature does not exceed 100°C, so can I scale it to the chart paper values of 0–100 (so that the chart records 100 when the temperature is 100°C)?

Yes. Set the range settings as follows.

Mode: Linear scaling

Range: 6 V

Left span: 1.000 V

Right span: 3.667 V

Left scale: 0.0

Right scale: 100.0

(Note: if the mode is 1–5 V, you cannot set the right span outside of 4.8–5.2 V.)
