WARNING
RISK OF ELECTRIC SHOCK OR FIRE:
USE ONLY INSULATED PROBES, TEST LEADS, AND
CONNECTORS SPECIFIED IN THIS MANUAL WHEN
MAKING MEASUREMENTS >42V PEAK (30V RMS)
ABOVE EARTH GROUND OR ON CIRCUITS >4800 VA.
USE PROBES AND TEST LEADS WITHIN RATINGS
AND INSPECT BEFORE USE.
REMOVE UNUSED PROBES AND TEST LEADS.
REMOVE PROBES AND TEST LEADS BEFORE
OPENING CASE OR BATTERY COVER.
WHEN THE SCOPEMETER TEST TOOL IS
CONNECTED TO ITS POWER ADAPTER/BATTERY
CHARGER, TERMINALS MAY BE LIVE, AND THE
OPENING OF COVERS OR REMOVAL OF PARTS
(EXCEPT THOSE THAT CAN BE ACCESSED BY HAND)
IS LIKELY TO EXPOSE LIVE PARTS.
THE TEST TOOL MUST BE DISCONNECTED FROM
ALL VOLTAGE SOURCES BEFORE IT IS OPENED FOR
ANY ADJUSTMENT, REPLACEMENT, MAINTENANCE,
OR REPAIR.
CAPACITORS INSIDE MAY STILL BE CHARGED EVEN
IF THE TEST TOOL HAS BEEN DISCONNECTED FROM
ALL VOLTAGE SOURCES.
CLEANING
Clean the ScopeMeter test tool with a damp cloth and a
mild detergent. Do not use abrasives, solvents, or alcohol.
KEEPING BATTERIES IN OPTIMAL
CONDITION
When new, the batteries typically provide 4 hours of use.
To keep batteries in optimal condition, do the following:
Always operate the test tool on batteries until a blinking
appears in the top right of the display. This indicates
that the battery level is too low and the batteries need to be
recharged.
CAUTION
Frequent charging of the batteries when they are not
completely empty can cause a "memory effect". This
means that the capacity of the NiCad batteries
decrease, causing a decrease in the operating time of
the test tool.
