Instrument Overview
RG-1 Operation Manual p/n 910702 Rev.0
1—2
The RG-1 is an automated gravity meter that has a worldwide measurement range of
7,000 mGals and a reading resolution of 0.001 mGal. This enables the user to operate in
both detailed micro-gravity surveys and large scale regional or geodetic surveys.
This self-leveling remote-operating gravity meter is designed to be incorporated into
vehicles or platforms for the purpose of acquiring gravity data remotely on the sea floor or
on land. It can be integrated into an existing AUV / ROV, requires low power and includes
a standard RS232 port for control and data output.
Protection from changes in ambient temperature and atmospheric pressure is achieved
by installing the RG-1 sensing element in a sealed temperature-stabilized chamber. The
broad operating temperature range of -40°C to +50°C enables the RG-1 to function in
most environments.
Internal tilt sensors constantly supply the RG-1 with tilt information in order to correct, in
real time, measurements taken on unstable ground.
The provided laptop computer allows the user to easily setup the RG-1 and store the
recorded gravity data. The laptop computer is pre-loaded with RGS software that allows
user to remotely setup, level, record, and continuously monitor gravity and other signals.
When the included battery and GPS antenna are attached to the RG-1 it can be used,
together with the laptop as a land gravity meter.
The included smart Li-ion rechargeable battery provide sufficient power to operate the
RG-1 throughout a normal survey day.

Unpacking the Instrument
The RG-1 is packed in a padded case (with the battery stored separately and packaged
individually to comply with IATA transport safety regulations) to protect the instrument
during shipment and transportation to the field.
Important: During shipment, the battery must be removed from the instrument
and stored separately. If you have just received your RG-1, the
battery will have a charge of approximately 30% and be
disconnected from the instrument.

1.Press the red pressure release valve located in the front of the transportation case.
2.Pull up the tab of a link lock and turn the tab counterclockwise to unfasten the lock from
the keeper plate.
3.Repeat step 2 for the other link locks.

4.Open the RG-1 transportation case by lifting the lid.
5.Remove the RG-1 from the transportation case by pulling directly upward on the handle
and visually inspect for any physical damage that may have occurred during
transportation.
Important: The RG-1transportation case has a shock watch monitor affixed to
the side of the shipping box. Inspect the monitor and if the vial is
red please contact Scintrex Limited immediately. Please refer to
“When to ship the unit” on page 6-5.

Assembling RG-1 to Stand-alone Configuration
Installing the external battery and GPS assembly enables the RG-1 remote gravity meter
to be operated as a stand-alone land gravity meter.
Note: To operate the meter and record data, RG-1 needs to be connected
to the supplied laptop via the provided RS232 cable [910532]
Installing External Battery Assembly
Remove 4X SCREWS TRUSS HD SLOT 10-32 3/8 ULTRA WD [330019] from RG-1
enclosure using screwdriver with SLOTTED INSERT BIT 14-16 from Tool kit, store
screws in BATTERY ASSY STORAGE BIN [910421]

Starting up the RG-1
Starting-up the RG-1 for the first time, or after it has been turned off for more than 24
hours, requires the following steps and waiting periods.
Powering up the RG-1: Please refer to the section entitled: Powering up the RG-1
below.
Warm-up period: after you power up the RG-1, it takes approximately one hour to reach
the operating temperature.
Stabilization period:the instrument takes 24 hours to stabilize after you power up.
Setting up the instrument for field operations:after the stabilization period your RG-1
is ready for field use. Refer to the next chapter (Operating RG-1 with RGS Software) for
details.
Powering up the RG-1
The RG-1 can be powered either by:
• The 15VDC external power supply, or
Figure 2-14 Connecting power supply to RG-1
• The external Smart Battery supplied with the RG-1.

Figure 2-15 RG-1 with External Smart Battery Installed
If the battery is in place when the external power supply is connected, the power supply
will power the unit and charge the battery if necessary. When the battery is fully charged,
the power supply will power the unit so that the battery maintains its full charge.
Charging takes approximately 4 hours if the battery has been fully discharged.
Charging the RG-1 Battery
In addition to being charged in-situ in the RG-1, battery can also be charged with the
Smart Battery Charger [400209],
To charge battery, open Battery Assembly as shown (no need to disconnect from RG-1
unit).
Seal should be properly oriented, with “LID SIDE” facing end cover with window.
