a continuous beep sound as soon as the sensor tip
contacts the metal part.
- The recommended ambient testing temperature is from
15°C to 30°C. The temperature of the stone should be the
same as the ambient temperature. Exceeding the ambient
temperature of 30°C, the test result may be incorrect.
- In case if the red light becomes dimmer, the battery has
to be replaced.
- When testing small stones (10pt or below), it is
recommended to take off the diamonds from the body, let
them cool down to room temperature (15°C to 30°C) and
then conduct testing. Otherwise the test result might also
be incorrect.
- When the switch is slid to ultraviolet, the ultraviolet LED
will light up. Then the diamond tester will test the
fluorescent reaction of stones under ultraviolet light.
- For a long time indoor use, an AC adapter (110V-240V,
DC 9V) is recommended (optional available)
- After using the tester, the ON/OFF switch always has to
be slid to OFF.
- There is no need to calibrate when the testing stones are
with sizes over 5pt.
- If the testing stones are with sizes less than 5pt, the
Level Meter Volume has to be adjusted to add the lighted
columns in LED level meter bars to meet special needs.
6. Maintenance
- If the diamond tester isn’t used for a longer period, the 9V
monobloc battery should be removed.
- The protective cover of the testing sensor should be
clipped on, if the tester is out of use.
- No other parts except the battery cover (to replace
battery) may be opened. This would void warranty.
- After a long time use, battery should be replaced, when it
has got a low power.
7. Caution
- The tester cannot distinguish synthetic Moissanites.
- Don’t look directly into the ultraviolet light; it may harm
your eyes!
