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 4314KV/KVS is powered by an internal rechargeable heavy-duty Nickel–metal hydride (NiMH)
battery pack. The battery charge is maintained by an external AC/DC converter that plugs into a standard
receptacle. The AC adapter can accept an input voltage from 100 to 240 Vac (50-60Hz) and an output of
6VDC @ 1.25mA.
The 4314KV/KVS must be turned off and have the adapter connected in order to charge the batteries.
The battery pack may power the 4314KV/KVS 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 4314KV/KVS 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.
Isolated AC version are available. Option AC115.
Installation
The Model 4314KV/KVS 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.
