Name: The logger is a user definable name to identify the logger. Up to 32
characters are allowed however, a continuous string of characters of more than 16
with no spaces may not be displayed correctly. Click on the field to enter
information.
Sensor Warm-up Time: To conserve battery life, the
sensors do not normally have power applied to them.
Before taking a reading, the logger powers up the
sensors for the sensor warm-up time, and then removes
power from them again. The allowable times are zero
(50mS) to 60 seconds. The sensor warm-up time for the
WQ-FDO sensor is 15 seconds. Click on the field to enter or
select the time in seconds from the pull-down menu.
Baud Rate: Leave this set to Auto Baud Rate.
Only change this to a fixed baud rate if planning to
use this logger in a telemetry application, such as
using Global Water’s Global Access radio modem
software. Once programmed in a fixed rate mode,
you must set the baud rate in the opening connection menu of the Global Logger II
software to this speed, or the logger will not communicate.
Sample Periodically: Sampling at regular intervals is the most common recording
mode. Click the Sample Periodically option, select the units from the pull-down
menu and click the numerical field to enter the number of those units up to 65,535.
Fast Sampling Mode: In Fast mode, the sample rate is fixed at 10 times per
second. The time stamp will not read fractions of a second so there will be 10
samples per time stamp. Click the Fast mode option to select this feature.
