probe is the output terminal of simulation voltage. 
2. Fixed frequency simulation 
This option enables you to simulate the square wave signal of pulse frequency 
of 0.1 ~ 15 kHz, amplitude range of -5V ~ +5V and duty cycle 10% ~ 90%. 
In Fig. 9-2, tap “Fixed frequency simulation” to enter a screen similar to Fig. 9-3.

Tap the setting option tab, then tap “+” or “-” to adjust the output. After setting, 
tap    to perform the test. 
3. Predefined waveform simulation
 
X-431  PAD  III  provides  some  common  sensor  waveforms  which  have  been 
predefined to facilitate users to simulate sensor signals. As long as you call out 
the  predefined  waveform,  then  tap    to  start  simulating  output  of 
corresponding sensor waveform and no more parameter settings of simulation 
waveform are required. 
In Fig. 9-3, tap “Predefined waveform simulation” to enter the screen shown as 
Fig. 9-4.
