the meter is not used in a manner specified
in this manual, the protection provided by
the meter may be impaired.
The Model UD87 comply with IEC 1010-
1 (1995), UL 3111-1 (6. 1994), EN 61010-
1 (1995), CSA C 22.2 No, 1010.1-92; Over
voltage 1000V Category III.
TERMS IN THIS MANUAL
A “WARNING” identifies conditions and
actions that could pose serious hazard to
the user.
A “CAUTION” identifies conditions and
actions that could cause damage the meter
or the equipment under test.
WARNING: DO NOT EXPOSE THE METER TO
RAIN OR MOISTURE IN ORDER TO REDUCE THE
RISK OF FIRE OR ELECTRIC SHOCK. TO AVOID
ANY ELECTRICAL SHOCK HAZARD, OBSERVE THE
PROPER SAFETY PRECAUTIONS WHEN WORKING
WITH VOLTAGES ABOVE 60V DC OR 30V AC RMS.
THESE VOLTAGE LEVELS REPRESENT A POTENTIAL
SHOCK HAZARD TO THE USER. INSPECT TEST
LEADS, CONNECTORS AND PROBES FOR DAMAGED
INSULATION OR EXPOSED METAL BEFORE USING
THE METER. IF ANY DEFECTS ARE FOUND, REPLACE
THEM IMMEDIATELY. DO NOT TOUCH TEST LEAD
TIPS OR THE CIRCUIT BEING TESTED WHILE POWER
IS APPLIED TO THE CIRCUIT UNDER TEST. ALWAYS
KEEP YOUR FINGERS BEHIND THE FINGER GUARDS
OF THE TEST LEADS DURING MEASUREMENT. DO
NOT MEASURE ANY CIRCUIT THAT DRAWS MORE
THAN THE PROTECTION FUSE’S CURRENT RATING.
DO NOT ATTEMPT THE PROTECTION FUSE’S
VOLTAGE RATING. NEVER ATTEMPT A VOLTAGE
MEASUREMENT WITH THE TEST LEAD INSERTED
INTO THE MA μA OR A INPUT TERMINAL. WHEN
SERVICING THE METER, USE ONLY SPECIFIED
REPLACEMENT PARTS. REMOVE TEST LEADS FROM
THE METER BEFORE YOU OPEN THE BATTERY
DOOR. DO NOT OPERATE THE METER WITH THE
BATTERY DOOR REMOVED OR LOOSENED. TO
AVOID FALSE READINGS, WHICH COULD RESULT IN
POSSIBLE ELECTRIC SHOCK OR PERSONAL INJURY,
REPLACE THE BATTERY AS SOON AS THE LOW
BATTERY INDICATOR APPEARS. AVOID WORKING
ALONE.
CAUTION: DISCONNECT THE TEST LEADS FROM
THE TEST TIPS BEFORE CHANGING FUNCTIONS.
DISCONNECT CIRCUIT POWER AND DISCHARGE
ALL HIGH-VOLTAGE CAPACITORS BEFORE
TESTING RESISTANCE, CONTINUITY, CAPACITANCE
OR DIODES. ALWAYS SET THE METER TO THE
HIGHEST RANGE AND WORK DOWNWARD FOR
AN UNKNOWN VALUE IN THE MANUAL RANGING
MODE. BEFORE MEASURING CURRENT, CHECK THE
METER’S FUSES AND TURN POWER OFF TO THE
CIRCUIT BEFORE CONNECTING THE METER TO THE
CIRCUIT.
