Purpose: high-end instrument for inspecting and appraising artefacts.

Technologies incorporated:

  • X-polar vision technology for observing the true colors of the artifact, and for studying details like signatures with much more contrast and definition. The image is seen through a 77mm +2D lens. Lighting by a 5W (CCT4000 – 4500) LED
  • UV beam (365 nm, narrow spectrum) for clearly detecting all kinds of materials like varnish, glue, metals and plastics. For safety reasons, it takes one second for the UV beam to reach full intensity.
  • Jeweler’s loupe for close inspection at 5cm, with a soft white lighting assist. (26mm +10D achromatic doublet lens)

The strong UV LED is potentially blinding and should never be looked into, or be pointed at anyone’s eyes!
Always keep the InSpector away from children!

General charging advice for Li-Ion batteries:

Charging the InSpector (from empty battery) for three hours will give you more than one hour continuous X-polar light, or more than one and a half hour of UV light.
If you expect to need more than that, you can charge the battery into full saturation by waiting for the red light to turn into green, after 4 to 6 hours. This wil give you app 30% extra time.

Not fully charging the battery increases battery life. It is advised to only fully charge if an intensive use is expected that day.
Recharging a partially discharged battery quite often, is not causing permanent capacity loss (as a “memory effect”), as long as a full discharge and charge cycle is performed once in every 25 cycles.

Do not leave the battery fully unloaded for a long time (several weeks).
Charging the InSpector in a below zero (C) temperature environment will seriously shorten battery life (f.i. loading in a parked car in winter).
Storing it at an elevated temperature (over 35C) can also damage your battery (f.i. in a parked car in summer).

Advanced charging advice:

Charging the battery up to saturation (green charging light) will give you the full battery capacity. But doing so too often, reduces the life expectancy of the battery. So loading cycles up to 50% of capacity (app. 2 hours from fully discharged battery) or 75% (app. 3 hours) are prefered.

For long periods (several months) of storage, it is best not to have the battery fully loaded, but only half.
So if the battery is not (close to being) discharged, it is best not to charge after use, but to charge the day before use.

Li-Ion batteries have a very low self-discharge, but a few percent of discharge per month can occur, especially when fully loaded and stored at an elevated temperature (f.i. cars in summer).
