PAUSE CONTINUE
Puts the instrument in PAUSE mode and switches off the voltage. The display shows the
status of the run at the time the key was pressed. PAUSE CONTINUE only operates in
RUN mode. Time, integrated voltage and integrated current are retained. In the pause
mode, SET ENTER can be used to make changes in the program. Return to RUN mode by
pressing PAUSE CONTINUE or by pressing RUN.
STOP
Stops the run and puts the instrument in END mode. The voltage is switched off and the
end parameters are displayed. Switch between time, integrated voltage and integrated
current by pressing

. A run cannot be continued after pressing STOP. Press RUN to
run the same method again or press SET ENTER to choose another program, program a
new method or make changes in an existing method.
INSERT DELETE
Press INSERT DELETE to insert or delete a phase in a program. This function is activated

The negative output socket gives between 0 and –1750 V and the positive gives between
0 and +1750 V.
