Hoefer PS2A200 - Manual (Page 25)

Adjusting parameters during a run
The location of the cursor indicates which param-
eter is being held constant, and this parameter can
be adjusted directly by pressing the (+) and (–)
adjust keys. Other parameters can be adjusted by
pressing the set/read key to switch to SET mode.
After 5 s of inactivity, the display automatically
reverts to READ mode.
At the end of the run
Once a time or volt-hour limit is reached, a 30
second beep sounds. The LCD will report that the
cycle is complete. At the end of a Time & Hold
run, there will be an additional message indicating
that the voltage output is being held at 5.0 V. Press-
ing any key will display the last parameters set.
Reviewing run parameters
After the run, the LCD will display statistics for
the completed run when both the HV power is
off (the HV lamp is not lit) and the set/read key
is pressed. The programmed settings and power
conditions at the start, midpoint, and end of the run
as well as the total volt-hours will be displayed.
Documentation
When using a serial printer to document run
parameters the recorded information includes the
instrument serial number and software version, the
protocol name and running conditions, a report of
the output every five minutes, indications of each
step change and the end of the run.
