Tested using GPS system.
3
For use to a stability of ±0.025ppm, the unit should be powered on continuously for 2 to 5 days after initial unpacking.
4
Tested using GPS system.
5
For 24 hours continuous operation within temperature limits (see footnotes 5 and 6) after GNSS training. Refer to cumulative error specification if operating in GNSS trained mode beyond 24 hours since last
training.
6
For less than 3 °C ambient temperature change after training.
7
For less than 10 °C ambient temperature change after training.
