5. Operation
5.1 Battery charging
Before use the CG100/500, please make sure the internal battery has been charged,
And the batteries completely charge is suggested.
During charging, the Power switch shall be in the OFF position!
The charger input of CG100/500 does not exceed 5.2Vdc.
5.2 General operation
5.2.1 Power On Switch
The switch turns the unit power on or off.
5.2.2 Power On Indicator
When the Power On indicator LED is lit the Comb Generator is ready for use.
3 LEDs lit, the battery level is 70~100%
2 LEDs lit, the battery level is 40~70%
1 LED lit, the battery level is 20~40%
If only one LED lit when power on, the battery level is 20~40%, please recharge
the CG100/500 unit. When all LEDs are dark at power on, that means critical low
battery, and must recharge the CG100/500 unit right now.
The LED will be flashing when the CG100/500 in charging status, and will all lit
when the battery is completely charged.

5.2.3 Connection with LISN
1. Connect an earth bonding wire from the earth stud on the CG100/500 to a
reliable earth point, ensuring a good connection.
2. Connect the supplied Power cord from the AC socket on the CG100/500 to
the mains EUT outlet on the LISN.
Ensure the connections to the receiver/analyzer are as used for measuring the
EUT, with any pre-amplifiers and/or transient limiters switched on.
5.2.4 Connection with ISN
1. Connect an earth bonding wire from the earth stud on the CG100/500 to a
reliable earth point, ensuring a good connection.
2. Connect the RJ-11 or RJ-45 cable from the RJ11/RJ45 connector on
CG100/500 to the RJ11/RJ45 connector on EUT port of ISN.
5.2.5 Recommends of site validation
The CG100/500 Comb generator can be used to validate test site or used to daily
check. In order to minimize the measure deviation, the same setup installation at
each test is in need, and the follow items have to be considered.
1. The same position and orientation of CG100/500.
2. The same cable placement, include Power cord, ground wire, RJ11 and RJ45
cables.
3. The same cable length, it would be best to use the same cable for each test.
4. Ground connection point must be connect to the same point for each test and
has good connection.
