CH1 is provided with
Overvoltage
function. When the output terminal is connected to an
external circuit, the relationships between the output voltage “Vout” of generator and the
voltage “Vin” possibly generated by external circuit are:
If Vout≤1V
DC
, the protective range of Vin is ± 6.5V
If Vout>1V
DC
, the protective range of Vin is ± 12.5V
Thereinto, Vout=Amplitude/2+|Offset|, the Amplitude and Offset are the parameters of
the signal outputted from generator.
The generator will cut off the output automatically when Vin exceeds the specified range.
The voltage inputted to the output connector of CH2 should be within
±
3V.
[3] External input voltage should be within ± 5V, or else the generator may be damaged.
