5. Operation

5.1 Overview

The operation of the EPS 601 is described in the following sequence.
1. Programming or editing a method.
2. Running a method.
When the method is running, it can be interrupted (put in PAUSE mode) to apply samples and/or change
the program. During a run it is also possible to look at the program settings.
Programming and running are discussed in more detail in the following two sections.
Blinking characters are shown as bold characters.
5.2 Programming
Start position
When the power supply is switched on, the display shows the start position in SET mode. The previous
program set is shown and that program number is blinking, for example:
SET:
200 V
(If the power supply is switched on for the first time, the breakpoint para-meter and the alarm are off
and the values for voltage, current, and power are 6 V, 400 mA and 100 W respectively).
Choosing a program
Up to 3 programs can be entered. Press ENTER to confirm the program shown on the display or use
/ keys to choose another. Confirm with ENTER. The programming procedure can be followed step
by step in Fig. 3.
Setting voltage, current and power limits
The display will now flash for the set voltage limit. Using the
desired for the run. Confirm with ENTER. Repeat the same procedure for limiting current and limiting
power. Programmable values for voltage are 6–600 V, current, 1–400 mA, power, 1–100 W, time,
0:01–500 h, volthours, 1–500 000 Vh.
Setting break-point
Choose between manual break or automatic break. For automatic break, choose breakpoint units in
either Volthours (Vh) or time (h). Select the
