8. Exponential Fall
The Exponential Fall waveform is as shown in the figure below.
The instrument determines the amplitude of the waveform according to the maximum (M) and minimum (N)
currently set and determines the waveform period according to the total number of points (P) and the time
interval (maximum 99999).
The fall index (R) is the independent variable of the fall function, which is an integer from 0 to 10. It determines
the falling speed of the waveform, and the base is Euler number (e=2.718281828).
The waveform function is �� ( �� ) = ( �� − �� ) ��
4.6 Delayer Templates
The optional delayer templates include: state generation, fix time, increase, and decline.
1. State Generation
The state generation mode is a template that controls the On/Off state of the output terminal. "0" means off
and "1" means on.
0 1 Pattern: the state is set to "Off" and "On" alternately.
1 0 Pattern: the state is set to "On" and "Off" alternately.
2. Fix Time
Fix time mode is a template for setting the output terminal on time (Max. 99999s) and off time (Max. 99999s).
Users set the output on delay time (the duration when the output status is "On") and the output off delay time
(the duration when the output status is "Off").
The default initial state of the group data generated by this template is the output off state.
3. Increase
Generate the on/off delay time by increasing from the time base value at the specified step (△t<99999s).
Delay time of next state = delay time of current state + step value;
The default initial state of the group data generated by this template is the output off state.
4. Decline
Generate the on/off delay time by declining from the time base value at the specified step (△t<99999s).
The default initial state of the group data generated by this template is the output off state.
