Installation of the model 7280 in the laboratory or on the production line is very
simple. It can be operated on almost any laboratory bench or be rack mounted, using
the optional accessory kit, at the user's convenience. With an ambient operating
temperature range of 0 ° C to 35 ° C, it is highly tolerant to environmental variables,
needing only to be protected from exposure to corrosive agents and liquids.
The instrument uses forced-air ventilation and as such should be located so that the
ventilation holes on the sides and rear panels are not obstructed. This condition is
best satisfied by leaving a space of at least 2" (5 cm) between the side and rear panels
and any adjacent surface.
An optional accessory kit, part number K02004, is available from
SIGNAL RECOVERY to allow the model 7280 to be mounted in a standard 19-inch
rack.
Upon receipt the model 7280 Lock-in Amplifier should be inspected for shipping
damage. If any is noted, SIGNAL RECOVERY should be notified immediately and
a claim filed with the carrier. The shipping container should be saved for inspection
by the carrier.
A standard IEC 320 socket is mounted on the rear panel of the instrument and a
suitable line cord is supplied.
Before plugging in the line cord, ensure that the model 7280 is set to the voltage of
the AC power supply to be used.
A detailed discussion of how to check and, if necessary, change the line voltage
setting follows.
CAUTION: The model 7280 may be damaged if the line voltage is set for 110 V AC
operation and it is turned on with 220 V AC applied to the power input connector.
The model 7280 can operate from any one of four different line voltage ranges, 90-
110 V, 110-130 V, 200-240 V, and 220-260 V, at 50-60 Hz. The change from one
range to another is made by repositioning a plug-in barrel selector internal to the Line
