INTRODUCTION
Thank you for buying SG1638N series function generator/counter.
Please read this manual carefully before operation and keep it well.
Suggest to use an oscilloscope to watch the waveform when operation.
Please select the real input voltage by the voltage selector
Instrument’s AC power supply should have safe GND.
Changing fuse should be fit for given request.
Each output, input port should not contact AC power supply.
Each output, input port should not contact over ±35V AC or DC power.
Output port should try to avoid long-time short circuit. (≤1min)
In order to ensure instrument’s accuracy, please avoid strong magnetoelectricity.
