CG-5 Gravity Meter Operation Manual - Scintrex

Getting Started• If you look into the compartment you will see the connector on the bottom ofthe rear panel of the compartment. Insert the battery with the socket down sothat it mates with the plug• Replace the battery compartment cover.Note:You will know if you insert the battery the wrongway because the battery compartment cover will notclose completely.Note:The state of charge of the batteries is given bythe small icon at the bottom of the screen or by thepressing the INFO key and displaying theinformation page as described later in this section.When a battery is outside of the gravity meter itscapacity can be observed on its own "Fuel Gauge".CG-5 BatteriesThe CG-5 uses rechargeable Lithium Ion "Smart Batteries". Each battery hasinternal sensors and a microcontroller which communicates with the batterycharger to optimize the charging cycle. These batteries have the followingspecifications:• Operating temperature range: -20 - +60 degrees C• Storage temperature range: -20 - +60 degrees C. For long periods it isrecommended to store below 25 degrees C• Charging temperature: 0 - 45 degrees C• Nominal voltage: 11.1V• Nominal Capacity 6.6AhWith two fully charged batteries the CG-5 will operate for longer than 14hours at 25 degrees C without the need for recharging. As the operatingtemperature drops the battery capacity is reduced. At temperatures below -20degrees C it is recommended that the optional battery belt be used.When the batteries are discharged to below 10% of the total capacity a beeperwill sound at 15 second intervals. At this point at least one charged batteryshould be installed in the CG-5 or the external supply should be connected. If1-14CG-5 Manual - part # 867700 Revision 5
