Predeployment Checks
Before configuring and deploying the CTD-N, you should perform some predeployment checks.
These checks comprise verifying adequate battery and memory capacity for the required length of
deployment and running the diagnostic tests on the instrument.
NOTE.
Diagnostic tests should be done in air in a constant unchanging environment.
Verifying Battery Pack Capacity and Memory Requirements
Before deploying the CTD-N you should verify that the battery pack capacity is sufficient for the in-
tended deployment period and that there is enough memory to store all the data acquired during
this period. CTDPro provides an estimator which calculates the available running days based on the
selected running mode and the known—or measured—battery pack capacity in the instrument. In
addition, the estimator calculates the number of days at which the memory will fill based on the se-
lected running mode and sampling rate. The calculated results are displayed and can be printed and
saved to a file.
NOTE.
External power must be disconnected to make this measurement effectively. Otherwise, CTDPro
will calculate longevity based on the external voltage supply rather than the battery pack itself.
To verify sufficient battery pack capacity and enough memory for a deployment:
1. If you want CTDPro to measure the battery pack capacity in the instrument when calculat-
ing the available running days, connect the instrument to your computer.
If you want to enter the battery pack capacity directly to calculate the available running
days, you do not have to connect the instrument to your computer.
