DANGER
Never make measurement on a circuit in which voltage over 600V rms exists. Use only leads
rated 600V CATIII or better.
Do not apply more than the rated voltage, as marked on the DMM, between terminals or be-
tween any terminal and earth ground.
Do not attempt a current measurement when the open voltage is above the fuse protection
rating. Suspected open circuit voltage can be checked with voltage function.
Do not use the DMM to measure voltages in circuits that could be damaged by the DMM’s low
input impedance in Lo-Z Function. Impedance is approximately 4K.
Do not attempt to make measurement in the presence of flammable gases. Otherwise, the use
of the instrument may cause sparking, which can lead to an explosion.
Never attempt to use the instrument if its surface or your hand is wet.
Do not exceed the maximum allowable input of any measuring range.
Only test on unenergized circuits unless absolutely necessary.
Check tool functionality on a known circuit first. Never assume tool is working.Assume circuits
are live until they can be proven de-energized.
Never open the Battery cover during a measurement.
Do not ground yourself while measuring. Avoid body contact with earthed or grounded sur-
faces such as pipes, radiators, ranges and refrigerators.
