2.1 Electrical Connections
To prevent instrument errors, make sure that the electrical
connections (Figure A1 - Item 10 and/or Figure A2) are
correct.
The Help button (Figure A3 - Item 25) shows a
connection diagram for the task selections you have
set.
2.2 Communications Port Connections
Use the communications port (Figure A1 - Item 9) to attach
an IDOS Universal Measurement Module (UMM).
When you attach the cable from a UMM (Figure 13 &
Figure 14), the instrument automatically changes the
menus to give you all the applicable options (Table 2 &
Table 3).
2.3 Change the Output Values
When the output operation is set up (Table 5), use one of
these procedures to change the output values:
Table 7: Menu options - Set Up
Output Procedure
Select Edit () and/or use the  buttons.
See the example below.
Select Start/Stop () or use the  buttons
,
to make the step changes manually.
Select Start/Stop ().

2.4 Measure/Supply mA
To measure/supply a current:
1. Connect the instrument (Figure 1, Figure 2 or Figure 3)
and, if necessary, adjust the Set Up (Table 1).
2. Select the task from the task selection menu (Table 2 &
Table 3).
Note: Use the Dual Function area () to do two
operations at the same time. If the area  selection is
not necessary, set this area to off (). This saves the
battery power.
