Power: illuminated in red indicating that the power is successfully connected. 
Output: illuminated in green indicating that the output is turned on. 
Link: illuminated in yellow indicating that the USB connection is successful. 
 
 
 
CAUTION 
The input impedance of the instrument (Zi) is 50kΩ. The range of the 
input voltage is from -10V to +10V when the voltage gain is X1 and from 
-1.25V to +1.25V when the voltage gain is X10. When the input exceeds 
these ranges, the instrument might be damaged or danger might occur. 
 
 
CAUTION 
The output impedance of the instrument (Zo) is lower than 2Ω. The range 
of the output voltage is from -
12V to +12V. The actual output voltage can 
reach ±12.5V, but the total harmonic distortion of the waveform will 
increase.
