5.Define the peak time and background time values 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.

3.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.
4.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
5.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%.
6.Press Right/Increase.
