EPLACEMENT
During the annual calibration of your HI-6053 at the ETS-Lindgren factory, the
batteries are tested to verify continued operability. If required, the batteries are
replaced at that time. It is rare that you should need to replace the batteries
between calibration checks, but in that event, follow these steps.
Note: If you are not qualified to perform this procedure, please
consult ETS-Lindgren Customer Service. ETS-Lindgren is not
responsible for damage to the probe as a result of replacing the
batteries.
Note: See the Product Information Bulletin included with your
shipment for information on ETS-Lindgren calibration services.
1. Turn the HI-6053 off. Verify that the green indicator light is not flashing.
2. Carefully disconnect the fiber optic cables from the Transmit and
Receive connectors.
3. Remove the two nuts; one on each fiber optic connector.
4. Remove the four screws from the bottom of the electronics housing.
5. Lift the bottom
away from the
housing. Wires
from the power
button are
connected to the
internal circuitry,
so carefully turn
the bottom over
and place it to the
side, avoiding
placing stress on
the wires.
