HELPFUL SUGGESTIONS
1. If substituting alkaline batteries
for the NiMH rechargeable
batteries, only use high-quality
AAA alkaline batteries.
2. The UltraTester 3+ is designed to
be able to easily test faceted or
rough stones of virtually all sizes.
However, please keep in mind
that small stones will naturally
heat up much faster after being
touched by the probe tip. After
each test be certain to cool off
the stone by blowing on it or
waiting a few seconds until it cools
if a retest is required. If testing
diamonds in a pave setting, please
note it is easy to accidentally
overheat the stones next to the
one being tested. Therefore, it is
very important that you test the
stones while alternating testing
one area of the ring and then
another, while regularly blowing
on the stones to cool them off.
3. The UltraTester 3+ has been
calibrated at the factory and
should not require further
calibration. If after using the
UltraTester 3+ it is determined that
recalibration is required, please
contact the factory for calibration
instructions, which can be easily
accomplished by any user.
