Tips for Users:

   • to keep the meter's battery fully charged, please keep it connected to the charger, power turned off, when not using it. In this way you will ensure that the meter is always ready when you will need it. Even if the battery would be fully charged, it is trickle-charged to keep it full; no harm is done.

    • avoid running the meter's battery completely empty. Recharging it would require more time than expected since the Lithium battery needs a refreshing initial charging before actual charge is put into it. Also, do not take as real the charge indicators when the battery has been run empty. They may show a full charge even though it is completely empty. Let it charge overnight to be sure.

if you wish to have your meter's internal software updated, just send the meter to Visilab and pay the freight cost both ways. We will not charge for the upgrade operation unless you wish to have something else too. We will give full support to all instruments we have manufactured.

there is a small bug in one of the latest versions of the internal software: When the Adjust fine tuning is performed, the current table becomes useless. Actually, it is turned to SCALE mode and nothing is lost, just turn it back to MULTI mode. If you observe this behavior in your instrument, you can send it to Visilab for upgrading. The corrected versions are 1.30N and up.

Optional Accessories:

    • A Power-user skid -PUS giving a full protection for the plastic case while measuring in difficult positions and against a moving web. A crude web surface may wear out the plastic case at the corners. -PUS has also a connector for air purge to prevent condensation and to keep the optical window clean. This option adds some to the total price. Mention this option while ordering. See pictures at the end of this page.
    • a carrying case -CAR at a very economical price. Keeps the meter protected and ready for use.
    • Advanced software license for an extended PC program
    • Moisture standard -STD for regular checking for long-term stability
    • a dual battery pack -DBAT for at least seven hours of continuous use. It adds only a little weight, nothing on the outside.
