8.BASIC PROGRAMMING

8.3 °C/°F Computation Selection

This programming is to select a “°C” or “°F” computation for a temperature range (thermocouple or resistance thermometer). The default setting is “°C”. Press SHIFT and simultaneously 3 seconds or more in the operation screen to display the “°C/°F computation” selection screen. Select “°F” if necessary.

1) In case of temperature unit “K”

The temperature unit for the range No.47 (AuFe-CR) and 80 (Pt-Co) is “K”. It does not affect this programming.

2) Influence onto other programmed parameters

The programmed parameters for “Range/Printing range”, “Scale” and “Alarm setpoint” are not changed automatically. If the programmed parameters cannot be used for the selected computation unit, reprogram them again. Even if “°C” or “°F” is programmed at the “Engineering unit programming”, it does not change the computation.
