SR570 Low-Noise Current Preamplifier
REPACKAGING FOR SHIPMENT
The original packing materials should be saved for
reshipment of the SR570. If the original packing
materials are not available, wrap the instrument in
polyethylene sheeting or equivalent and place in a
strong box, cushioning it on all sides by at least
three inches of high-density foam or other filler
material.
USE IN BIOMEDICAL APPLICATIONS
Under certain conditions, the SR570 may prove to
be unsafe for applications involving human
subjects. Incorrect grounding, component failure,
and excessive common-mode input voltages are
examples of conditions in which the instrument
may expose the subject to large input currents.
Therefore, Stanford Research Systems does not
recommend or approve the SR570 for such
applications.
WARNING REGARDING USE WITH
PHOTOMULTIPLIERS
The front-end amplifier of this instrument is easily
damaged if a photomultiplier is used improperly
with the amplifier. When left completely
unterminated, a cable connected to a PMT can
charge to several hundred volts in a relatively
short time. If this cable is connected to the inputs
of the SR570, the stored charge may damage the
front-end op amps. To avoid this problem, always
connect the PMT output to the SR570 input before
turning the PMT on.

WARNING REGARDING BATTERY
MAINTENANCE.
Batteries used in this instrument are sealed lead
acid batteries. With usage and time these batteries
can leak. Always use and store this instrument in
the feet-down position. To prevent possible
damage to the circuitboard, it is recommended that
the batteries be periodically inspected for any
signs of leakage.
