Temperature characteristic
• “Measurement accuracy × 0.1/°C” is
added (excluding 23°C ± 5°C (73.0°F ±
9.0°F)).

range, “Measurement
accuracy × 0.4/°C” is added (excluding
23°C ± 5°C (73.0°F ± 9.0°F)).
Other conditions
The accuracy of the two connected L4931
Extension Cable Sets (3 m) is guaranteed.
• rdg. (reading or displayed value): The value currently being measured and
displayed on the measuring instrument.
• dgt. (resolution): The smallest displayable unit, i.e., the input value that
causes the digital display to show a “1”.
