Chapter 2 – Unpacking and Installing
Inspection
If the shipping carton is damaged, request that the carrier's agent be present when the unit is unpacked.
If the instrument appears damaged, the carrier's agent should authorize repairs before the unit is returned
to the factory. Even if the instrument appears undamaged, it may have suffered internal damage in transit
that may not be evident until the unit is operated or tested to verify conformance with its specifications.
If the unit fails to operate or fails to meet the performance specifications of Chapter 3, notify the carrier's
agent and the nearest Valhalla Sales Office. Retain the shipping carton for the carrier's inspection. DO
NOT return equipment to Valhalla Scientific or any of its sales offices prior to obtaining authorization to
do so.
Power Requirements
The Model Alpha 4314 is powered by an internal rechargeable heavy-duty NiMH battery pack. The battery
charge is maintained by an external AC/DC converter that plugs into a standard 100-240Vac 50-60Hz
receptacle. The AC adapter provides 6VDC @ 1.25A.
For safety reasons, the Alpha 4314 may not be powered directly from the AC adapter. The Alpha 4314
must be turned off and have the adapter connected in order to charge the batteries.
The battery pack may power the Alpha 4314 for up to 10 hours before requiring a recharge.
Although the batteries are fully charged prior to shipment, it may be desirable to refresh the charge for
24 hours before use. As a rule of thumb, the Alpha 4314 requires twice as much time to fully recharge as
the amount of discharge time. For example, if the instrument was used continuously for 2 hours, the AC
adapter must be connected for 4 hours in order to fully restore the charge.
To avoid damage, do not turn on the Alpha 4314 while connected to a load.
Installation
The Model Alpha 4314 consumes little power and generates virtually no heat. Consequently, it may be
used in any area where the environment does not exceed the temperature specifications of Chapter 3.
A rack mount adapter is available to allow installation of the Alpha 4314 in a standard 19" equipment rack.
This option is designated as Option R4. When installing this instrument in a rack environment, avoid
exposing the Alpha 4314 to extremes of temperature, which will affect the accuracy and shorten battery
life-span. For installation instructions, please refer to the drawing included with the option.
