1
The voltage gain is inverted to preserve the high slew rate of the output amplifier (i.e., a -1 V input results in
+20 V output).
2
The HV output will handle an accidental short circuit without damage, but the output should not be shorted
continuously.
3
The HV monitor output will handle accidental short circuits without damage, but must not be shorted for more
than 5 sec to prevent excessive heating of the output resistor. The HV monitor output will source up to 200 mA
when a short circuit is applied.
