SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, "metallized" knobs, screws,
and ali other exposed metal parts for AC leakage. Check leakage as
described below.
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 0.5mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. Acommercial 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.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the equipment manufacturer. Discard
used batteries according to manufacturer's instructions.
ADVERSEL !
Lithiumbatteri ~ Eksplosionsfare ved fejlagtig handtering.
Udskiftning ma kun ske med batteri
af samme fabrikat og type.
Lever det brugte batteri tilbage til leverandcren.
ADVARSEL
Lithiumbatteri — Eksplosjonsfare.
Ved utskifting benyttes kun batteri som
anbefalt av apparatfabrikanten.
Brukt batteri returneres apparatleveranderen.
VARNING
Explosionsfara vid felaktigt batteribyte.
Anvand samma batterityp eller en likvardig typ som
rekommenderas av apparattillverkaren.
Kassera anvant batteri enligt gallande féreskrifter.
VAROITUS
Paristo voi rajahtaa, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittelemaan
tyyppiin. Havita kaytetty paristo valmistajan ohjeiden
mukaisesti.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The "limit" indica-
tion is 0.75V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are
suitable. (See Fig.A)
