c) 2
nd
value selection
When this key is pressed it allows the selection of a 2
nd
phase angle and it is
shown in the display. This selection does not cancel the angle already
selected in the output at the moment. To distinguish the actual angle from
the 2
nd
value selected, the LED over the key lit when the 2
nd
value is
displayed.
d) Activating 2
nd
value
This key works in a sequential way. When pressed the phase angle in the
output changes to the 2
nd
value, when it is pressed again it will return to the
1
st
value.
When this key and the similar key in the phase section are pressed at the same time for
more than 2 seconds this function if both sections becomes synchronized. To cancel you
must repeat this process.
e) 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:
•
Current:
0 - 0.33 A
0 - 8 A
0 - 25 A
0 - 50 A
•
Voltage:
0 - 6.25 V
0 - 150 V
This key is associated with the 4 red LEDs with the ranges marked and the display in this
section.
