Operating Manual V 3.3 / 9 Dec 2019
MARWIS-UMB
6 Operation modes
6.1 Normal operation
The MARWIS-UMB / STARWIS-UMB is switched on and off by connecting and disconnecting
the power supply.
After being switched on it takes a starting time of about 10 seconds before the first measure-
ment values appear. Depending on the operating temperature and on the current ambient
temperature a warm up phase of 5 up to 15 minutes may be required before the first plausible
values appear. This period can be reduced if the MARWIS-UMB STARWIS-UMB is powered
with 24 V (as opposed to 12 V). The state of readiness is indicated by the status LED turning
green or blue respectively in case the Bluetooth connection is active. The meanings of the
status LED's colours are described in chapter 4.12 on page 12.
