The ranges for both ApK and AbK are 2.0 to 400 am-
peres, in increments of 1.0 ampere.
3. Press Right/Increase, and the display shows:
# 0 X P E A K T I M E = X .X X
B A C K T I M E = X .X X
4. Define the peak time and background time as desired.
Peak time is the length of time the pulse is at the peak
level. Background time is the length of time the pulse is
at the background level.
The ranges for both peak and background times are
0.5 to 5.0 seconds, in increments of 0.5 seconds.
5. Press Right/Increase, and the display shows:
# 0 X F R E Q U E N C Y =
X X .X X P U L S E S / S E C O N D
6. This display is for informational purposes. It indicates
the calculated frequency of pulses per second.
7. Press Right/Increase.
If the Process Selector switch is in the ac output posi-
tion, go to Section 5-3D if programming in
Semi-Automatic 1 or 5 modes; go to Section 5-3E if pro-
gramming in Semi-Automatic 2, 3, or 4 modes.
If the Process Selector switch is in a dc output position,
go to Step 8.
8. The display shows:
# 0 X A V G C U R R E N T =
X X X .X A M P S
9. This display is for informational purposes. It indicates
the calculated average current during pulsing.
10. Press Right/Increase. Go to Section 5-3D if program-
ming in Semi-Automatic 1 or 5 modes. Go to Section
5-3E if programming in Semi-Automatic 2, 3, or 4
modes.
C. Procedure With Pulse Mode On, Pulses Defined
As A Frequency
1. The display shows:
# 0 X P U L S E A p K = X X X .X
P U L S E A b K = X X X .X
2. Define the ApK and AbK values as desired.
ApK defines the peak current during pulsing. AbK
defines the background current.
The ranges for both ApK and AbK are 2.0 to 400 am-
peres, in increments of 1.0 ampere.
3. Press Right/Increase, and the display shows:
# 0 X P U L S E S / S E C = X X .X
P U L S E P E A K % = X X
4. Define the pulse frequency per second and the per-
centage of pulse time to be spent in pulse peak as
desired.
The range for pulse frequency is 0.1 to 10.0 pulses per
second, in increments of 0.1 pulses per second.
The range for percentage of pulse time to be spent in
pulse peak is 5% to 95%, in increments of 1%.
5. Press Right/Increase.
If the Process Selector switch is in the ac output posi-
tion, go to Section 5-3D if programming in
Semi-Automatic 1 or 5 modes; go to Section 5-3E if pro-
gramming in Semi-Automatic 2, 3, or 4 modes.
If the Process Selector switch is in a dc output position,
go to Step 6.
6. The display shows:
# 0 X A V G C U R R E N T =
X X X .X A M P S
7. This display is for informational purposes. It indicates
the calculated average current during pulsing.
8. Press Right/Increase. Go to Section 5-3D if program-
ming in Semi-Automatic 1 or 5 modes. Go to Section
5-3E if programming in Semi-Automatic 2, 3, or 4
modes.
D. Procedure Following Pulse Mode Definition For
Semi-Automatic 1 And 5 Modes
1. The display shows:
# 0 X F I N A L S L O P E
T I M E = X X .X
2. Define the final slope time as desired.
The range for final slope time is 0.0 to 25.0 seconds, in
increments of 0.1 seconds. Define the final slope time
as desired.
3. Press Right/Increase, and the display shows:
# 0 X F I N A L
T I M E = X X .X A M P S = X X X .X
4. Define the final current time and amperage as desired.
The range for final current level time is 0.0 to 25.0 sec-
onds, in increments of 0.1 seconds. The range for final
level amperage varies from 2.0 to 400 amperes, in in-
crements of 1.0 amperes.
