6. [.a]
The [.a] command is used to set the start and stop times for a specified
measurement interval. This command could be used in the process to
qualify a site for appropriate amounts of background radiation.
This parameter is only made use of when the CS725 is in the manual
mode. The CS725 is placed in in the manual mode by entering the
Parameter menu [.p] and set parameter 19 to 1 for manual mode.
Once the parameter is set (the setting will be saved automatically), use the
.a command to specify the delay and duration in seconds. For qualifying a
site, it is recommended that the sensor be setup in the desired location and
the delay of 5 be used with a duration of 3600 seconds (1 hour) as a
minimum. The example below shows the syntax for the recommended
delay and duration for the manual measurement:
(Delay should be larger or equal to 5s)
Format =>Delay Duration
=>5 3600<Enter>
After completion, the [.hr] command can then be used to view the results
in detail. If the CS725 is placed in Auto or HCalib mode, the following
message will be printed:
This function should be called in manual mode only.
7. [.t]
The [.t] command is used to read the internal temperature sensor of the
CS725 (degrees Celsius). This feature is mainly used for diagnostics to
apply temperature compensations. Temperature measurements are made
inside of the internal electronics and on the surface of the gamma detector
crystal. The output format is as follows:
temp crystal:23 temp electronics:27
8. [.d]
The [.d] command is used to display the current date and time. The
display order is:
Day of Month/Month/Year <4 space characters>
Hour:Min:Sec<CR><LF>
The format is as follows: 16/09/2009 15:00:20
The CS725 does not perform any time zone or daylight-savings time
correction. This can be done in the datalogger.
