1. AC power supply and power supply with adapter
The accompanying AC-DC adapter must be used for AC power supply. The input power supply of the adapter
is 100~240V, 50/60Hz AC.
When transported and carried in a backpack, please do not connect the AC-DC adapter to the device to
avoided overheating. The AC-DC adapter has a wide range of voltage input. When in use, please make sure
the power supply voltage is within the scope specified in Table 2.1.

3. Power supply with built-in battery
S3302 can be powered by rechargeable li-ion battery. The battery will discharge if it is not used for a long time.
Therefore, the battery must be recharged before use. Please refer to Section 2.6 for details about battery use. Basic
parameters of accompanying battery are as follows:
Nominal voltage: 10.8V
Nominal capacity: 7,800mAh
CAUTION
The rechargeable battery must not be exposed to fire or high-temperature environments
(above 70
℃
), or placed in fresh water or salt water, or made wet. It must be kept away from
children.
The rechargeable battery is reusable and should be stored in proper container to avoid
short circuit. Heavy metals such as nickel and chromium in the battery can pollute natural
environment. Waste battery shall not be discarded but shall be put into a special battery
recycle box.
2.1.3 Electrostatic discharge (ESD) protection
Electrostatic discharge is extremely destructive to electronic components and equipment, so the powered
instrument must be operated on a workbench with ESD protection. So please pay attention to ensuring ESD
protection when using the instrument. The following ESD protection measures can be taken if conditions are met:
1. Before connecting the cable to the instrument for testing, be sure to ground the center conductor of the cable
first. The following steps can be used: Connect a short-circuiter at one end of the cable to short the center
