| My
Model 2300 seems to produce a DC offset when placed
in current mode. How can I eliminate this offset? |
| You can eliminate the offset by AC-coupling the output of the Model 2300 (provided you are trying to generate a biphasic waveform). There are two concerns in using this method: the limited bandwidth and DC offsets in general. Any DC offset, no matter how small, will charge the capacitor in the AC-coupling circuit over time to the point where the output amplifier saturates, and can no longer produce the requested output current. For more information on AC-coupling the output of a Model 2300, please contact our technical support team (tech@a-msystems.com).

| My
Model 2300 is beeping at me, indicating the battery
is low, but the battery test light illuminates, indicating
OK levels. How can this be? |
| The
9V battery has discharged below acceptable levels, but
it is still slightly strong enough to partially light
the led. It needs to be replaced.

| My
Model 2300 is not working, but our university has an
excellent electronics facility. Can we repair the unit
ourselves? |
| It
is recommended that A-M Systems perform the needed repairs
as we are the most familiar with the units. However,
if you are confident in your electronic technician's
skills, you can always purchase the schematics for the
Model 2300 from us and attempt them yourself.
Please
note that any user-attempted repairs during the warranty
period may invalidate the warranty, and might invoke
additional charges to correct them if A-M Systems is
required to make repairs at a later date.

| Can
I use this instrument outside of the United States? |
| All
of A-M Systems instruments can be modified to work outside
of the United States. Typically, this modification is
made at the factory (at no additional cost) prior to
shipping to our customers. Just inform the customer
service department where the instrument will be used,
so our technicians can prepare the proper power supply
modifications.
