8. Exponential Falling Wave
The maximum (denoted as M) and the minimum (denoted as N) of the wave determines the amplitude of the
wave.
The total count (denoted as P) and the time interval (maximum 9999.9) determines the wave period.
The fall index (denoted as R) is the independent variable of the fall function, which is set as an integer from
0 to 10 in this system to determine how fast or slow the waveform falls, and the base is Euler's number (e=
2.718281828);
The function of the exponential falling wave is defined as:
(x is the independent variable and can be taken as an integer from 0 to P-1.)
3.11.2 Delayer Settings
1. Press the list key on the panel multiple times to enter Delayer page;
2. Click on the basic setting to set the start point, count, times and stop state. The maximum sum of
the start point and the count is 512.
The cycle count can set to 1 to 99999 or “Inf”;
Stop: set the condition of voltage, current and power. The delayer will stop when meets the
condition.
3. Click on the Edit button to set the parameter of each point or it can set by Template in batches;
4. After the parameter is set, click on the Start button to operating the delayer;
The delayer will stop when meets the condition or it can stop manually, and the delayer will set the
power output according to the stop state of the user-defined.
