Counter-clockwise for 1 beep to measure of a positive or negative pulse.

Signal Generator Mode  

    Sine, triangle, and rectangle signals are generated. The signal is applied to the device probes. It is 
possible to adjust the span (peak-to-peak) of a signal from 0.1 to 2.8 V, a constant bias of ± 0.6 V *, and a 
duty cycle of 5 - 95% in 5% increments. Parameters are stored when exiting the mode. On the right of 
the screen from top to bottom: sweep, offset, duty cycle and the waveform icon. The frequency in Hz is 
displayed in the center of the screen. 

 

The self-shutdown time is 4 times longer than the default in other modes. An external decoupling 
capacitor is required to supply a signal to a circuit under voltage. It should be connected to a probe 
located closer to the side switch. The other probe is a common one. In this mode, the device does not 
turn-off by "flipping" and the function of automatic change of display orientation (left/right hand) is 
disabled. It is recommended to use LCR-Reader Kelvin Probe Connector to simplify the device operation 
in this mode.

Controls 

 

Clockwise for 1 beep to select the item to change. 

 

Counter-clockwise for 1 beep to increase the selected parameter.
