1. When testing the un-erased or un-filed portion, be sure that the test area has

been relatively unaffected by wear. Flat or thin Gold plated items will tend

to be "worn around the edges". If it is difficult not to expose a worn area

when testing an un-erased or unfilled area, the user may wish to selectively

mask any area in question with fast drying lacquer. The reason for masking

a worn surface first is that you may obtain the lower Karat reading before

any erasing or filing has been accomplished. Therefore you may not get a

lower Karat value on your second test and not be able to determine that you

are testing Gold Plate.

2. When testing the erased or filed portion, be sure that enough of the surface

area immersed in the liquid is erased or filed down to expose the suspected

"base metal" underneath.

The same Electrolyte can be used for the two comparisons, (the un-erased

or un-filed area test and the erased or filed test).

No maintenance is required outside of cleaning after testing as described in Step

9 of the Operating Instructions. (page 5)

When the Low Battery indicator comes on, it is necessary to replace the batteries

before operating the unit. Simply remove the 4 small screws located on the rear

of the Gold Tester, under the black rubber screw covers. Carefully remove the

rear cover. Locate the three "AA" batteries being very careful to observe the

correct polarity as shown on the battery holder. Insert batteries according to the

original polarity; replace the rear cover, being careful not to pinch the wire leads

with the cover.
