1. Safety Information

This meter has met IEC61010-1 and IEC-61010-2-032 
standards with an overvoltage category of 600V CAT III 
and a pollution degree of 2. Follow safe operation 
procedures to ensure the long life and safe use of this 
instrument.  

WARNING

1.1 Preparation

1.1.1 When using the meter, follow the following 
          safety rules:
          -Take precautions to prevent electrical shock
          -Do not misuse the instrument
1.1.2 Check the meter and accessories thoroughly 
          before using.
1.1.3 Check to see if the meter or any components 
          were damaged during shipment.
1.1.4 Inspect test leads and probes for cracks, breaks 
          or crazes on the insulation before using the meter.
1.1.5 Use test leads provided with the unit.  If 
          necessary, replace test leads with identical 
          specifications.

1.2 Usage

1.2.1 Turn the rotary switch to the required function 
          and range to be measured.
1.2.2 Never use the meter to measure voltages that 
          might exceed 600V DC/AC above earth ground.
1.2.3 Always be careful when working with voltages 
          above 60V DC or 30V AC RMS. Keep fingers 
          behind the probe barriers while measuring.
1.2.4 The “     ” symbol next to the input lead shows 
          that the input voltage or current should not 
          exceed the specified value in order to protect the 
          internal circuit from damage.
1.2.5 Choose the highest range when the value to be 
          measured is unknown.
1.2.6 Remove test leads before switching functions on 
          the rotary switch.
1.2.7 Do not perform resistance, capacitance, diode 
          and continuity measurements on powered circuits.
1.2.8 Never connect the test leads across a voltage 
          source while the rotary switch is in the resistance, 
          diode or continuity mode. Doing so can damage 
          the meter.
1.2.9 Power off the circuit and discharge capacitors 
          before testing capacitance.
1.2.10 Do not place the meter in any environment with 
            high pressure, high temperature, dust, explosive 
            gas or vapor.
1.2.11 Stop using the meter if any failure or abnormal 
            function is observed.
1.2.12 Do not use meter unless battery cover is in place 
            a secured.

TO REDUCE THE RISK OF FIRE, ELECTRICAL 
SHOCK, PRODUCT DAMAGE OR PERSONAL 
INJURY, PLEASE FOLLOW THE SAFETY 
INSTRUCTIONS DESCRIBED IN THE USER 
MANUAL. READ THE USER MANUALS 
BEFORE USING THE METER.
