9.3 Accuracy

Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and dgt. (digit) values, with the
following meanings:
Guaranteed accuracy conditions
9.3 Accuracy
f.s. (maximum display value)
The maximum displayable value. This is usually the name of the currently selected range.
rdg. (reading or displayed value)
The value currently being measured and indicated on the measuring instrument.
dgt. (resolution)
The smallest displayable unit on a digital measuring instrument, i.e., the input value that causes the
digital display to show a "1" as the least-significant digit.

1 year
Guaranteed accuracy for
temperature and humidity
23°C ± 5°C (73°F ± 9°F), 80% RH or less (no condensation)
Warm-up time At least 30 minutes, after zero adjustment
Average function ON, 4 times
Measurement state Measurement taken in the same measuring environment as was in place
when zero adjustment was performed, including identical probe profile and
placement. Probe profile must not be changed during measurement.
Self calibration Except when using SLOW sampling, self-calibration should be executed after
warm-up.
Ambient temperature after self-calibration should be maintained within ± 2
°C.
