Selecting the temperature unit (TEMP)
The temperature unit can be selected from the following;
•
°C which is the initial value, or
•
°F
Note
• In the User’s manual all functions and operations are explained using the
°C unit. When using the °F
unit, replace the
°C unit with the °F unit. For the measurement range/measurement accuracy and
maximum resolution in case of using the
°F range, refer to the following table as a replacement of the one
on page 14-2.
• Measurement range: Refer to the following table;
• Measurement accuracy/maximum resolution: Replace the values using the following formula
°F = (°C value × 9/5) + 32
• When changing the temperature unit as descibred above, other settings will be initialized at the same time
and therefore, all settings need to be done again. This initialization will be the same initialization as
described on page 9-17.
• In order to make the set or selected contents effective, the contents must be registered. For details, see
page 10-24.
• To return from the SET UP menu to the operation display mode, select END in the main menu. For
details, see page 10-24.
