Setting the clock - Sync to PC
The logger clock may be synchronized with the host PC by pressing the
Sync to
PC
button (confirm PC clock first).
Start of logging, End of logging, Sampling period and Averaging
period
All of these parameters may be set in the
Date and time picker
window which
will open after clicking one of these buttons. The parameters will be set into the
logger when the
Enable logging
button is pressed.
The Date and time picker window:
The current date is circled in red and the target date is highlighted in blue.
The
Start time
date and time picker may be ignored by clicking on
Now
. If
Now
is selected, the
Start time
calendar is hidden and the logger will start within 10 to
20 seconds of being enabled.
The minimum
Sample period
for the DR-1050, TR-1050/1060, 2050 family and
XR-420 series of loggers is 1 sample/second. The XR-620 series, however, is
capable of sampling at a rate of 6 Hz.
At the bottom left of the dialog box is the logger capacity calculation. The
memory usage and the battery usage of the proposed deployment are shown.
The battery usage is based on a de-rated battery capacity from the nominal
1300mAH to 1000mAH. The battery usage is offered as a guide, further derating
may be necessary for operation in cold conditions. See the section on
Setup
simulation
(p.24) for a way to calculate battery usage for any particular
deployment as well as Appendix A (p.44) for more information. If the RS485
serial protocol is employed, an additional drain is imposed on the battery. If the
RBR Windows Software considers that your logger may be using RS485, an
additional battery usage value will appear in the window.
