Electrostatic protection
Electrostatic protection can always be ignored. Discharge of static electricity accumulated on the human
body can damage the sensitive circuit component inside the instrument, lowering the instrument
reliability dramatically. Even the undetected tiny static electricity discharge can damage the instrument
permanently. Therefore, whenever possible, the following electrostatic protection measures should be
taken as far as possible
：
a) Conduct the test on the workbench with earthing and conductive table mat.
b) Wear static-proof wrist strap and connect the strap to the conductive table mat when touching
devices and accessories and testing.
c) Wear static-proof wrist strap when working in areas with conductive ground, even when such
ground conductivity is uncertain.
d) Make yourself earthed once by holding the earthed instrument test port or shell of the test cable
connector when cleaning/checking the test ports for electrostatic sensitive devices and
instruments or conducting connection.
e) Do earth the cable center conductor first before connecting the cable to the instrument test port
or electrostatic sensitive devices via the following means: Connect a short-circuit device to one
end of the cable to realize short circuit between the cable and center conductor, or hold the
shell of the cable connector tightly, connect the other end of the cable, and the remove the
short-circuit device when wearing the static-proof wrist strap.

Battery installation and replacement
The S5105D/E/F microwave analyzer is provided with a high-capacity rechargeable lithium battery, with
a cruising power of up to 2h. Users can buy backup batteries for long-time out-field test, so as to avoid
any test interruption due to insufficient battery capacity. Take the battery out of the battery cartridge in
case of transportation or long-time storage, so as to guarantee the battery life.
The battery installation steps are as follows:
Open the battery cover, put the battery into the battery cartridge, push the battery in, and close the
battery cover.
2
Charging the battery
The S5105D/E/F microwave analyzer is provided with a rechargeable lithium battery, with the
charging steps shown below:
a) Shutdown the microwave analyzer, and place the battery into the battery cartridge.
b) Connect the output connector of the adapter to the power supply input port of the microwave
analyzer.
c) Connect the connector of the adapter to the 220V AC power supply via a power cord. At this
time, the power supply indicator light on the front panel of the microwave analyzer flashes in
yellow, and the battery will be charged quickly. After charging, the indicator light is normally on,
and the charger will be shut down automatically to protect the battery.
When the microwave analyzer is shut down or started up, installed with battery, and connected with the
adapter with insufficient power, the system will control the charger to charge the battery automatically till
it is fully charged.
NOTE:
The battery must be charged with the charging device matching the
microwave analyzer or battery, with continuous charging or not more than
24 h!
