j)
RS-232 OUTPUT - An RS-232 port is provided at the rear of the unit (behind the battery door)
marked COM. The GR-130 is supplied with a customized cable that permits direct connection of
this port to a PC. This port can be used to download data memory from the GR-130 as well as
providing complete REMOTE control for special applications. Special user libraries can be
uploaded into the GR-130 memory as well.
k)
SYSTEM SUPPORT SOFTWARE - Support software is provided with the GR-130 on the disks
labeled SpecView. This is a Windows based program and operates under Windows 95 or 98.
The program is described in Appendix B and provides data downloading, data display, custom
library uploading and some processing - as well as ASCII downloading to produce the data in a
format suitable for importing into various Spreadsheet programs.
l)
TEST SOURCE - The GR-130 is supplied with a 0.25 µCi Cesium-137 source (does not require
licensing) to stabilize the GR-130 for Analysis and Dose Meter modes. To prevent accidental loss
of this small source and to ensure correct placement, the test source is supplied in a cylindrical
tube (1" long x 1.25" diam - 25mm L x 30mm D). The source is sized to fit exactly in the hole at
the end of the boot, thus placing the source at the correct location for system stabilization.
m)
VINYL CARRYING CASE - The system is supplied with a soft vinyl carrying case with shoulder
strap for easy transportation of the GR-130. An easy-open zipper flap allows access to the
instrument while providing additional weather protection. The carry-case also has an external
pocket for carrying note books, etc.
n)
MANUAL - This user manual is supplied with the instrument.
o)
SHIPPING/STORAGE CASE - The GR-130 system is shipped to the customer in a rugged black
polyurethane carrying case that is fully waterproof and highly shock resistant. This case is
intended for shipping and/or storage purposes. It is equipped with a pressure purge valve and is
capable of withstanding air-cargo shipping abuse while offering a high level of protection to the
instrument.
On site, most users carry the GR-130 in the vinyl carry-case leaving the storage case back at the
office. However, if the unit is to be transported under conditions where it could be bumped or
dropped, the shipping case is recommended and would prevent other luggage from damaging
the instrument.
NOTE :
Even if the user does not intend to use the polyurethane storage case, it should be kept in
storage as Exploranium will only honor the full instrument warranty if the GR-130 is returned
in this (or a similar) case.
p)
HIGH DYNAMIC RANGE G-M TUBE - The GR-130 is equipped with a G-M TUBE to extend the
dynamic range in the survey mode and for measuring high dose rate.
q)
DOCKING STATION OPTION - A DOCKING STATION is optionally available for the GR-130.
This device is a cradle that the GR-130 unit sites in. The cradle is connected to the AC
connection, has an internal radioactive source and may be connected to a PC. 3 “fingers” on the
base of the GR-130 connect to mating 3 fingers on the Docking Station to provide charging and
data connections without opening the rear access data door. Some users find that the Docking
Station internal source makes it easier to control sources as the normal source supplied is small
and may be misplaced. Please contact Exploranium if this option is of interest.
