2. Connect a 1.5k
capacitor, between each exposed metallic part on the set an a
good earth ground such as a water pipe, as shown in Figure1.
3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallic part, and measure the voltage at
each point.
5. Reverses the AC plug in the AC outlet repeat each of the above
measurements.
6. The potential at any point should not exceed 0.15 volts RMS. A
leakage current tester (Simpson Model 229 equivalent) may be
used to make the hot checks, leakage current must not exceed
0.1 milliamp. In case a measurement is outside of the limits
specified, there is a possibility of a shock hazard, and the
equipment should be repaired and rechecked before it is returned
to the customer.
ABOUT LEAD FREE SOLDER (PbF)
Distinction of Pbf PCB:
PCBs (manufactured) using lead free solder will have a PbF indication on the PCB.
Caution:
1. Pb free solder has a higher melting point than standard solder;
Typically the melting point is 50-70°F (30-40°C) higher. Please use
a high temperature soldering iron. In case of the soldering iron
with temperature control, please set it to 700±20°F (370±10°C ).
2. Pb free solder will tend to splash when heated too high (about
1100°F /600°C ).
ELECTROSTATICALLY SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatically sensitive (ED) Devices. Examples of typical
