WARNING : Use caution when measuring high voltage circuits to avoid electrical shock and injury. Do not test voltages higher than DC/AC 600V.
WARNING : Never use the meter to measure voltages that might exceed 600V DC/AC above earth ground.
WARNING : Always be careful when working with voltages above 60V DC or 30V AC RMS. Keep ngers behind the probe barriers while measuring.
• Display shows voltage polarity (connected with red test probe) when measuring DC voltage.
• In low voltage ranges, unsteady readings will appear before the test leads makes contact with the circuit. This is normal as the meter is highly sensitive. When test leads are connected
to the circuit, the true reading will be shown.
• When ‘1’ is shown on the LCD under any range mode, the measurement has exceeded the allowable range. A higher range should be selected.
• When the value to be measured is unknown, select the highest range rst and lower the range accordingly.

WARNING : Turn off the power to the circuit to be tested. Discharge all high voltage capacitors on the circuit to be tested.
WARNING : To prevent injury or damage to meter or equipment, do not make current measurements if voltage exceeds 600V. Indicates the maximum current of the mA jack is
200mA and the maximum current of the 10A jack is 10A. Exceeding 200mA between COM and mA, or 10A between COM and 10A will blow the protection fuses.
WARNING : Set corresponding range. Example: When the measured current is under 200mA, plug the red test lead into “mA” jack and turn the dial to “200mA”; when the current to be
measured is over 200mA but under 10A, plug the red test lead into the “10A” jack and turn the dial to “10A”.
• Before measuring current, rst check the meter’s fuse. When measuring, use correct input end and function. When the test probe is inserted to the current input end, don’t connect the
other end of the test probe with any circuit in parallel.
• Display shows voltage polarity (connected with red test probe) when measuring DC voltage.
• When ‘1’ is shown on the LCD under any range mode, the measurement has exceeded the allowable range. A higher range should be selected.

WARNING : When measuring resistance or circuit continuity, to avoid injury or meter damage, turn off the power to circuit and discharge all capacitors.
• Under any range mode, when only ‘1’ is shown on the LCD, it means the measurement has exceeded the range and a higher range should be selected.
• When the input is open, ‘1’ is displayed on the LCD to indicate overload. For measuring resistance above 1MΩ, it may take a few seconds to get a steady reading. This is normal for
high resistance measurements.

WARNING
To avoid electric shock or personal injury, please read “safety instructions,
warnings and cautions carefully before use.
SAFETY INSTRUCTIONS: Read Before Use
The UTLDM1 digital multi-meter has been designed according to International Electro
Safety Standard IEC-1010 (61010-1@IEC: 2001) concerning safety requirements for
electronic measuring instruments and hand-held digital multi-meters. It meets the
requirements for CAT III 600V of IEC1010 and grade 2 for pollution.
▶Before using the meter, read all safety information carefully. Throughout the manual,
the word “WARNING” is used to indicate conditions or actions that may pose physi-
cal hazards to the user. The word “CAUTION” is used to indicate conditions or actions
that may damage this instrument.
▶WARNING! To reduce the risk of fire, electrical shock, product damage or personal
injury, please follow the safety instructions described in the user’s manual. Read the
user’s manual before using the meter.
▶CAUTION! To ensure safe operation and life of the meter, do not place the meter in
any environment with high pressure, high temperature, dust, explosive gas or vapor.
IMPORTANT SAFETY INFORMATION
▶Avoid shaking, dropping, or any direct impact when using or transporting the Detector.
▶To avoid electric shock or personal injury, repairs or servicing not covered in this manual
should be performed only by qualified personnel.
▶Avoid direct exposure to sunlight to ensure extended life of the Detector.
▶Do not place the meter in a strong magnetic field; this may cause false readings.
▶Only use batteries indicated in the technical specifications.
▶Avoid exposing batteries to humidity. Replace batteries as soon as the low battery
indicator appears.
PREPARATION
• Switch on power by turning the rotary switch. If the battery voltage is lower than 2.8V,
the “ ” symbol will appear and the batteries should be replaced.
• The “ ” symbol next to the input lead indicates that the input voltage or current
should not exceed the specified value in order to protect the internal circuit from dam-
age.
• Turn the rotary switch to the required function and range to be measured.
• Choose the highest range when the value to be measured is unknown.
• When making connection, connect the common test lead first and then the powered
test lead.
• Removed the charged test lead first when disconnecting.
