Temperature (TC
type K; internal
reference point
measurement:
measuring range 0 to
+40 °C, accuracy
±0.5 °C)
Measuring range: -200.0 to +1370.0 °C
Accuracy: ±(0.3 °C + 0.1 % of meas. val.)
Resolution: 0.1 °C
The accuracy information applies in
an adjusted, stable temperature
state. Plugging in the mains unit,
charging the battery or adding
digital probes can distort this
temporarily, and additional errors
may occur.
Differential pressure Measuring range: -100 to +100 hPa
Accuracy

: 0...+25 hPa:
±(0,3 Pa + 1% of meas. val.)
+25.001 to +100hPa:
±(0,1 hPa + 1.5% of meas. val.)
Resolution: 0.001 hPa
The accuracy specification applies
immediately after zeroing of the
sensor. For long-term
measurements, mains operation
with fully-charged battery is
recommended.
