3. Components of the Multi Tester
4. Battery and Power
The Multi Tester can be powered either by a universal AC
power adaptor (optional item) or one 9V PP3 battery (not
included in delivery).
If using the universal power adaptor, only the 9V DC 0.5A
(centre negative) original one from your distributor
has to be taken, which can be purchased separately.
Using an incorrect adaptor can damage the Multi Tester
beyond repair, which will not be covered by warranty.
If using a battery, it is recommended to buy a good quality
9V alkaline battery like Duracell or UCAR, which will grant
about 2 ½ hours of continuous use or 5 hours without
using the UV-light. Ordinary “super” or “high power”
batteries may not be suitable.
On the first picture on the left, above, you see how to
remove the battery cover.
On the second one on the right, above, the new battery is
connected with the contacts of the Multi Tester.
The third picture down below on the left shows how to
insert the battery into the compartment.
The last one shows how the compartment is closed again,
by taking care not to catch the wire.
If the Multi Tester is accidently left powered on, then after
10 minutes a continuous alarm will sound and if it isn’t
used immediately afterwards, it will be powered off
automatically.
When the WAIT light flashes, the battery is low and it
should be changed immediately. It should always be
changed immediately as soon as it flashes. Tests should
not be performed with a low battery.
If the Multi Tester is not going to be used for an extended
period of time (more than one month), the battery has to
be removed. Never leave a worn out or old battery inside
as it may corrode and cause damage to the Multi Tester.
This is not covered by warranty.
5. Important notes before use
Using the Multi Tester for the first time, or if it hasn’t been
used for a week or more, the sensor tip has to be cleaned
to ensure that the tester shows consistent and accurate
readings (see also “cleaning procedures”).
Before any test is carried out, the gemstone must be clean
and dry. This has to be done with a jewellery cloth or dry
tissue. There is no need to elaborate cleaning procedures
or to take special cleaning fluids.
This instrument has been carefully calibrated during the
manufacturing process, it doesn’t require any further
adjustment or interventions.
When testing small gemstones (10 points or below), it is
important to allow the gemstones to cool down before
further tests are carried out, to gain optimum accuracy in
tests.
If you are suspecting any doubts during the tests in your
readings, it is advisable to take any more tests, to be
assured that the gemstone has got enough time to cool
down during the tests. Gemstones become hot when
tested, which gives a false reading.
The Multi Tester will give accurate readings when it will be
used at the recommended room temperature of 18°C to
27°C (64°F to 81°F). It should be assured that the
gemstone has been adjusted to the recommended room
temperature before using the tester.
Before the Multi Tester was quality assured and sold, it
was subjected to thorough and extensive laboratory tests
until its manufacturing process was started.
It will generally give a clear and reliably reading of the
gemstone being tested. If there are any doubts in the tests,
supporting tests should be carried out.

distributers or third parties shall be liable under no
