M24 OWNERS MANUAL
IMPORTANT WARNING
BEFORE USING PROFESSIONAL MODEL M24,
READ ALL INSTRUCTIONS AND SAFETY DATA
AT THE END OF THE DOCUMENT.
This manual covers the operation of the M24 Electronic Gold Tester.
RS MIZAR, INC. has been issued two Patents for its development on
the M24 full range Gold Tester. This new process gives accurate and non-
destructive test results all the way to 24K gold. It can help determine Gold
Karat value in as little as 2 seconds.
This process can distinguish non-gold and gold plate from true "Karat Gold"
without the destructive Fire Assay testing, which would change the value of
the jewelry.
RS Mizar now brings you the fastest and easiest Gold Analyzer for all the
trades where jewelry and "Karat Gold" have to be quickly and accurately
evaluated.

OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS FOR TESTING GOLD FROM 20K TO 24K
When testing Gold from 9K to18K, go directly to instructions below for 9 to
18 Karat testing. When testing Gold from 20K to 24K, a buildup of test
solution on the Reference Gold will have to be removed to obtain the proper
results.
3
STEP A - Sharpen the Pencil Eraser and then cut off the end with a sharp knife or razor
so that it is flat and round (about .160" or 5/32"). Then place the eraser into the Test Well
and firmly rotate back and forth for about four seconds. Then brush debris from the Test
Well. This preparation will eliminate the excess buildup on the Reference Gold. For all
tests of 20K to 24K Gold do this step of removing excess buildup on the Reference Gold
with the sharpened and blade-cut Pencil Eraser. A dirty Eraser tip will not sufficiently
clean Test Well.
STEP B - Go to "item 1" below.
OPERATING INSTRUCTIONS FOR TESTING GOLD FROM 9K TO 18K.
ITEM 1
Thoroughly clean immersible area of Test Gold with the Gray Eraser (see
"DO'S & DON'TS", item 5.) Attach Alligator Clip to Test Gold away from immersible
area.
ITEM 2
Loosen the cap of the Test Solution and have a soft paper towel and some Q-
TIPS handy.
ITEM 3 Press "TEST YELLOW GOLD" or "TEST WHITE GOLD" (to match the type
of Gold that you are testing) and within two seconds, put three or more drops of Test
Solution into the Test Well. Quickly squeeze all of the air out of the Test Solution Bottle
and tighten cap firmly. (See "item 6")
ITEM 4
Observe that one of the Karat Value Lights is on. Any Karat Light may be lit;
this is determined by a previous test or length of time that the unit has been off. After the
Light goes out, (within one second), carefully immerse enough of the Test Gold into the
liquid to start the "Testing" Light being careful not to touch the reference Gold at the
bottom of the Test Well and being careful not to touch the Alligator Clip to the liquid.
Hold the Test Gold without moving it until "TESTING" Light goes off. This will take 2
to 15 seconds, depending on the Karat value of the Test Gold. User should brace the
"heel" of his hand on the unit or on the same surface as the unit rests on. When possible,
brace the Test Gold on the inside of the Test Well just under the surface of the liquid and
be very careful not to touch the Reference Gold at the bottom of the Test Well.
It is important that the Test Gold not be moved about in the Test Solution until a reading
is obtained.

ITEM 5
When "TESTING" Light goes out, remove Test Gold. Read LED
Display of Karat Value. Clean Test Gold thoroughly with soft paper towel.
Thoroughly wipe the Test Solution from the Test Well using a paper towel
followed by a Q-Tip. If re-testing is desired, see "DO'S & DON'TS", items
"8" and "11".
ITEM 6 Check to be sure that there is not excessive air in the bottle and that
the cap is tightened firmly.
PRECAUTIONS
• After testing Gold item, it should be cleaned with a buffing wheel.
However, it must be cleaned with the gray eraser before any new test
because of the residue left on the Gold from the previous test.
• Improper of insufficient cleaning of the test Gold before testing can
increase the karat value readings.
• Your unit is operating correctly if occasionally you do get a reading in the
next range. This can happen when the karat value of the Gold you are
testing is very close to the odd karat value, i.e. 17K, 19K, etc. Your unit is
operating correctly when this occurs and indicates the Gold you are testing
is very near the in-between value.
• The excess air must be squeezed out of the test solution bottle between
tests or when stored. Squeezing out the excess air keeps the solution
fresh. When all of the air cannot be squeezed out it needs to be replaced.
In any case, the bottle must be replaced 6 months after first opening! "Un-
fresh" test solution can cause the karat readings to go lower by one range.
You should always have a fresh bottle of test solution available. Record
here the date the bottle was opened:______________________

DO'S & DON'TS
1) Don't use Testing Solution for more than one test; errors will result.
2) Don't touch Test Gold or Alligator Clip lead to Reference Gold at bottom of Test
Well. If this happens remove liquid and re-do test procedure.
3) Don't let Alligator Clip touch liquid.
4) Don't leave liquid in test well. This will void your warranty.
5) Do clean Test Gold before testing if it isn't bright and shiny. Unclean Gold may
result in inaccurate readings.
6) Do keep Gold chains very tight (link to link) during testing. Use the fewest number
of links (one if possible) between the Alligator Clip lead and the Gold link to be
immersed in to the liquid. Three problems can exist with testing chains:
a. There may be dirt or contamination between links that would require intensive
cleaning (i.e. ultrasonic) before testing.
b. Some chains, especially certain European manufactured chains have a thin
non-metallic coating that must be removed from an area before testing. The
eraser pencil may be used to remove this coating.
c. When testing chains, remember that the solder often used at the link(s) is of a
lower Karat than the rest of the chain. Therefore, avoid testing in that area.
7) Do make sure good contact is achieved between the Test Gold and the Alligator
Clip lead. If the object to be tested is too large to fit in the clip lead, simply hold
the clip lead lightly against the Test Gold during test.
8) Do always clean the Test Gold with the Gray Eraser before retesting in the same
location. Pink eraser can be used but it requires considerably more pressure and
effort for accurate readings.
9) Do replace the Testing Solution every 6 months after opening.
10)Do use only within Operating Temperature 65°F-90°F.
NOTES
1) In the event the Alligator Clip contacts the testing solution, the Alligator
Clip must be rinsed thoroughly with water and dried before using again.
2) WARNING: Eye Hazard -- Read warning label on bottle of Test Solution.
3) IMPORTANT: The Testing solution is sensitive to exposure to air. Minimize the
time cap is loose on bottle.
