•
If the output range is changed in CH1, it changes immediately in the SLAVE
channels.
•
Any action made in the output control ON/OFF in CH1 occurs immediately in the
SLAVE channels.
•
Any action made in the
Step to 2
nd
Value
control in CH1 happens immediately in
the SLAVE channel.
•
The only operation made in CH1 than it is not immediately reflected in the SLAVE
channels is the
2
nd
Value Selection
that must be activated channel by channel in
any case.
•
The SLAVE channels remain independent in terms of control. It means that any
action made in a SLAVE channel only affects itself.
3.3.1.2. OPTICAL INDICATORS AND DISPLAYS
a) LED indicator for 2
nd
value selection
This is a 3 mm, red LED that is situated over the corresponding key. When this
LED is lit, it indicates that it is in the
2
nd
Value Selection
mode and that this value
is shown in the display.
b) LED indicator when 2
nd
value is activated
This is a 3 mm, red LED that is situated over its corresponding press key. It has
two states:
•
Not lit: indicates that the value in the output is the first value.
•
Lit: indicates that the value has changed to the second value.
c) Output range and output type selection
This key has two function modes:
1. Selection of the output type: this key serves to select the output type desired, that is
voltage (V) or current (I). When turning on the unit it will be in current output. To change
this output to voltage you must press this key for more than 2 seconds. To change this
output back to current, repeat the process.
2. Output range selection: this key also serves to select the output range, in voltage and
current. This key works in a sequential way: each time it is pressed it will change the
output range. There are 2 ranges in voltage and 4 ranges in current. They are:
•
Voltage:
0 - 6.25 V
0 - 150 V
