n This instrument is EN61010-1 certified for Installation Category III. It
is recommended for use in distribution level and fixed installations, as
well as lesser installations, and not for primary supply lines, overhead
lines and cable systems. n
overload conditions up to the limits of each function's stated input
protection (see Specifications). Never exceed these limits nor the ratings
marked on the instrument itself. n
may be present at all other terminals n
measuring voltage >20V, current >10mA, AC power line with inductive
loads, AC power line during electrical storms. High voltages can be lethal
and high voltage transients may occur at any time. n Operator injury or
damage to the multimeter may occur during current measurements if the
fuse blows in a circuit with open circuit voltage >600V (250 V in mA
input). n
Always inspect your DMM, test leads and accessories for
sign of damage or abnormality before every use. If abnormal condition
exist (broken or damaged test leads, cracked case, display not reading,
etc.), do not use. n When testing for voltage or current, make sure these
ranges function correctly. Take a reading of a known voltage or current
first. n
Never ground yourself when taking measurements. Do not
touch exposed metal pipes, outlets, fixtures, etc., which might be at
ground potential. Keep your body isolated from ground and never touch
exposed wiring, connections, test probe tips, or any live circuit
conductors. n Always measure current in series with the load – NEVER
connect the multimeter ACROSS a voltage source. Check fuse first. n
Never replace a fuse with one of a different rating. n
instrument in an explosive atmosphere (flammable gases, fumes, vapor,
dust.) n
Do not use this or any piece of test equipment without proper
training n
CRT SERVICE SAFETY REMINDER : A potential danger
exists when measuring voltages in the horizontal output and damper
stages of CRT equipment. (High voltage transients greater than 6,000 V).
Refer to your CRT service manual for proper servicing instructions.
