Software for Archer-OBS Manual

Section 1. Operations
1.12 Cyclic Sampling
This mode is for logging data at regular time intervals such as 1, 10, 15, 30,
etc. minutes for example.
1. Request
Barometric Correction. Be sure to do this while the
OBS-3A is at the surface. Doing so when the instrument is submerged
will result in large depth errors.
2. Click
and select sensors, statistics, depth units (meters or feet),
water temperature, and salinity. Selection of temperature and salinity only
affects the depth calculation. It does not influence temperature or salinity
measurements.
3. Configure the Wave Setup if you want to measure wave heights and
periods (see Section 1.8—Definitions). Do this before scheduling the
other sample parameters.
4. Select Interval, Duration, Rate, and Power level; see recommendations
in “Sampling Schedules” (Section 1.9). The duration must be longer than
the Record Length. The minimum duration for the Record Length will
be computed and displayed by the OBS-Mobile.
5. Click Start Sampling to begin logging data. Unplug test cable; install
dummy plug and locking sleeve. The instrument is ready for deployment.
