Description
Press set enter to enter a value or choice, confirm this if
valid, and move programming to the next field. Valid
values are voltage 35–3 500 V, current 1–400 mA, power
1–200 W, time 0:01–500 h, volthours 1–500 000 Vh,
milliampere-hours 1–25 000 mAh.
In the RUN mode, pressing set enter shows the
programmed parameters for the actual run. In addition,
set enter allows you to make changes in the program
during a run after first pressing pause continue.
After a run, when in END mode, pressing set enter puts

choice in the field which is blinking. Numerical values are
changed in an accelerating manner when a key is held
down. Clicking a key changes the value in preset
increments. Parameters or units (e.g. Vh) and choices (e.g.
Yes/No) are changed with one key push. The keys can also
be used to switch between time and volthours in RUN,
PAUSE and END. The values scroll i.e. they automatically
change from maximum to minimum value or vice versa.
Press run to start the run and put the program into RUN
mode. The current values for voltage, current and power
are shown on the display. The elapsed time, volthours or
milliamperehours are also displayed. Switch between
these last three parameters with
Press pause continue to put the instrument in PAUSE
mode and switch off the voltage. The display shows the

In the PAUSE MODE mode, set enter can be used to make
changes in the program. Return to RUN mode by pressing
pause continue or by pressing run.
Press STOP to stop the run and put the instrument in END
mode. The voltage is switched off and the end parameters
