IMPORTANT
To terminate the communication session and power down the sensor, press [CTRL]-[C] at
anytime, regardless of the current operational mode of the CTD. Note that if you are operating
the MMP with Version 2.07 or earlier you must place the CTD (and ACM) in open mode
manually before terminating the session. Some early models of the CTD could lose calibration
constants if shut down in run mode. See the CTD manual for further information.
Standard CTD settings exist for use with the MMP. The system will check for these
settings at the discretion of the operator before beginning a deployment. However, the system
will not automatically program the standard settings. The CTD pass-through utility can be used
to verify and program the standard settings before a deployment.
