Preparation
Installing the Batteries
Orion Star LogR series meters use four AA alkaline batteries. Do not use lithium or
rechargeable batteries. Improper installation of non-alkaline batteries could create a
hazard.
Note: For benchtop meters, the installation of batteries is not required if the unit
will always be connected to a power source via the universal power supply.
1. Confirm that the meter is off and gently place the meter upside down on a
clean, lint-free cloth to prevent scratching the LCD.
2. Remove the battery case cover.
3. Insert new batteries with the + side orientation as depicted in the battery
compartment housing.
4. Replace the battery case cover.
5. Stored data, calibrations and methods will remain in the meter's nonvolatile
memory when the batteries are being replaced. However, the date and time
may need to be reset when the batteries are changed.
