Using the Autolog Feature with Battery Power, But Without the Battery End Cap Switch
The steps for using the Autolog feature on a battery powered instrument without the end cap switch
as opposed to one with the end cap switch are a little different. First, without a way to externally
break and make the connection from the battery to the instrument, the instrument will be depleting
the battery from the time it is setup to the time it is deployed. If this time is short, then the end cap
switch isn’t greatly missed. Secondly, the user must ensure that the instrument is commanded into
run mode using CTDPro’s terminal window, as cycling the power is not an option with the battery
enclosed in the instrument. To command the instrument to run mode type “***R” in the terminal
window and hit the ‘Enter’ key. The user can avoid wasting battery energy and avoid having to com-
mand the instrument to run mode by installing the battery after the instrument’s Autolog feature is
enabled (as well as saved) and before the instrument is to be deployed.
Using the Autolog Feature with Permanent External Power
If the instrument is externally powered and the power can not be cycled for any reason, then the
user must ensure that the instrument is commanded into run mode in order to activate the Autolog
feature. To command the instrument to run mode, type “***R” in the terminal window and hit the
‘Enter’ key.
