Hoefer PS2A200 - Manual (Page 19)

Setting constant current output
1
Select “Const Amp”
Place the cursor in the first field of the second line by
pressing the select arrow keys (left and right arrows
under the display). Then press the adjust arrow keys
(pointing up and down) until “
Const Amp” displays in
the field.
As you scroll through the four options, a short beep
indicates each change.
2
Set the amp value
Place the cursor under the digit in the mA digit field
that you wish to change by pressing the select arrow
keys. Select the value of the digit by pressing the adjust
arrow keys. The (+) arrow increases the value, and the
(–) arrow decreases the value. A short beep indicates
that the change was registered. Repeat for each of the
four active digits in this field (1–2000 mA).
3
When the start/stop key is pressed to start the run, the
cursor will be in the mA field to indicate that this value
is being held constant. So long as the cursor is in the
mA field, this value can be edited without switching to
SET mode. To edit other parameters during a run, press
the set/read key.

#1 Protocol 1
Const Amp 2000mA
Timed Hrs
Step 1 10:00 hrs
Note: The output jacks are in
parallel. If both pairs of jacks
are used, the total mA value
displayed will be divided between
the loads in inverse proportion
to the resistance of each load.
For two identical loads to be run
at constant mA, set twice the
current desired for a single load.
The set voltage is supplied to
both pairs of output jacks.
