Operate with variable gain control or at a fixed
gain setting of 20.
•
Select Controlled-Current or Controlled-Voltage
modes of operation.
•
Trigger Standby mode when specified fault
conditions occur during operation.
•
Select the Stop mode state at power-up, or go
immediately to the Run mode state at power-up.
•
Configure for use in high voltage applications,
high current applications, or for applications
requiring mid-level amounts of both voltage
and current.
Your 2105 amplifier has been pre-configured to
