FOR SATELLITE ANTENNAS:SAFETY CHECK-OUT
1. Check the area of your repair for unsoldered or poorly-
soldered connections. Check the entire board surface for
solder splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground
straps, and mounting hardware have been replaced. Be
absolutely certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recom-
mend the replacement of any such line cord to the
customer.
7. Check the B+ and HV to see if they are specified
values. Make sure your instruments are accurate; be
suspicious of your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
leakage using one of the methods listed.
Figure 1. Using an AC voltmeter to check AC leakage.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any exposed
metal part having a return to chassis, must not exceed 0.5
mA (500 microamperes). Leakage current can be mea-
sured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229
or RCA WT-540A. Follow the manufacturers’ instructions
to use these instruments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means
of a VOM or battery-operated AC voltmeter. The “limit”
indication is 0.75 V, so analog meters must have an
accurate low-voltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of passive VOMs that are
suitable. Nearly all battery operated digital multimeters
that have a 2 VAC range are suitable. (See Figure 1)
