4.3. First Start
1. Connect the power cable to the POWER connector.
2. The green AC LED indicator must turn on,
If not:
▪
In case of AC powered Instrument:
Disconnect the power cable from the Instrument.
Open the Lid of the Instrument (refer to section 3.5).
Check if the internal FUSE is blown.
If so, then replace it with a 500 mA slow blow fuse.
Check if the AC power is present at the plug.
▪
In case of DC powered Instrument:
Check the power supply to the Instrument and the cabling.
Check the power delivery from the power supply in accordance with section 4.2.2.
3. When the problem is solved, reconnect the power cable to the Instrument.
4. Open the Lid of the Instrument (refer to section 3.5).
5. Insert the memory card if applicable.
6. Flip the main switch to its ON position.
The green RUN LED flashes once per second during the "Turn-On Delay" time (default 15
seconds). Afterwards it changes to one pulse every two seconds. This indicates that the instrument
is running.
Do not move or vibrate the sensor during the power up cycle. The Instrument is
calculating the baseline of the incoming signals; any noise could distort these signals.
You can now configure the operation parameters, start data acquisition or leave the Instrument for
operation with the actual configuration as described in the following sections.
4.4. Configuring Parameters and Putting in Operation
For configuration and data acquisition a PC running GeoDAS has to be used.
a
For the installation and usage of GeoDAS refer to the GeoDAS Manual, which explains the use
of the software in full details.
The typical procedure to be followed is to connect the cable from the PC to the RS-232 Port of the
Instrument and follow the steps described in the GeoDAS Manual to configure or perform following
functions:
•
Login to and Communication with the Instrument.
•
Verifying the operation of the Instrument and its sensor via Analog Signals.
•
Setting Date and Time.
•
Saving and/or Loading Configuration File.
•
Setting Recording parameters
•
Retrieving and Managing files
4.4.1. Serial Data Output
a
Only in GSR-18 delivered with “Serial Data Output” option.
With this option enabled, the Instrument will send out serial data stream through the RS-232
connection when the user logs out. As soon as GeoDAS is used to login, the Instrument stops the
data output.
The serial data stream of the Instrument contains all three channels. Depending on the configuration
that has been set via GeoDAS, it is possible to enable or disable the serial data output and select
between two modes of operation:
•
Sample Oriented Mode (SOM): After logout, every sample is sent to the communication line.
