Internal clock
±1 minute/month (18°C ... 28 °C)
The specifications apply under the following conditions:
- Annual recalibration,
- a warming up time of 10 minutes,
- an ambient temperature of 18 .. 28°C.
If the device is operated outside the range from 18 .. 28°C an additional measurement error equal
to ±0.01% of the measured value must be taken into account per °C difference.
Measurement uncertainty
The measurement uncertainty of the UMG604 applies to use of the following measuring ranges.
The measured value must lie within the given limits. Outside these limits the measurement
uncertainty is unspecified.
