SAFETY INFORMATION

This meter is CUL and UL approved and conforms to IEC 61010-1 for Cat-

egory III - 600V and Category II - 1000V. This meter is designed to be safe 

under the following conditions: indoor use, altitude up to 2000m, temperature 

5°C to 40°C, maximum relative humidity 80% for temperatures up to 31°C 

decreasing  linearly  to  50%  relative  humidity  at  40°C  and  rated  pollution 

degree  2.  Caution  and  proper  guidelines  must  be  followed  for  personal 

and product safety. Read this instruction manual carefully and completely 

before using the meter. Lack of caution or poor safety practices can result 

in serious injury or death.
•  This meter is not recommended for high voltage industrial use; for 

example, do not use for measurement on 440VAC or 600VAC industrial 

power mains. The unit is intended for use with low energy circuits up to 

600VDC / 600VAC or high energy circuits up to 250VAC / 250VDC only. 

•  Use caution when working above 60VDC or 30VAC RMS as these volt-

ages pose a shock hazard.

•  Always consider circuits to be energized. Never assume any equipment 

to be de-energized. 

•  Always start with power off. Set the function switch to the correct setting 

before making any measurements and do not change position of the 

function switch during measurements.

•  Never connect unit to AC or DC powered circuits when the function 

switch is set to resistance, diode check or continuity ranges.

•  Always disconnect the power when performing resistance, diode or 

capacitance tests. Discharge capacitor before testing.

•  Disconnect the live/positive test lead (red) prior to disconnecting the 

common/negative test lead (black).

•  When 

 appears on the display, change both batteries to achieve 

more accurate readings.

•  Disconnect the test leads before removing the batteries or the fuse.
•  Do not operate the unit unless the case is completely closed.
•  When using the test probes always keep fingers behind the finger 

guards. Never touch the exposed probe tip.

•  Always inspect the instrument, test leads and other accessories for 

damage prior to use.

•  Use only UL recognized test leads (included with this meter).
