SAFETY INFORMATION

This meter is CUL and UL approved and conforms to IEC 61010-1 for 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 the battery immediately.
•  Disconnect test leads from the meter before removing the battery 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).
