WARNINGS AND PRECAUTIONS
■
This instrument is IEC1010-1 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.
■
All inputs are protected against continuous
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.
■
Voltages applied to COM terminal may
be present at all other terminals
■
Exercise extreme caution when:
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.
■
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).
■
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.
■
When testing for voltage or current, make sure these
ranges function correctly. Take a reading of a known voltage or current
first.
■
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.
■
Always measure current in series with the load – NEVER connect the
multimeter ACROSS a voltage source. Check fuse first.
■
Never replace a
fuse with one of a different rating.
■
Do not operate instrument in an
explosive atmosphere (flammable gases, fumes, vapor, dust.)
■
Do not
use this or any piece of test equipment without proper training
■
C RT
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.
D • Warnungen und Vorsichtsmaßnahmen
■
Dieses Gerät ist IEC1010-1 zertifiziert für Installationsklasse III. Anwendung ist
empfohlen auf Verteilerebene und festen Anlagen sowie untergeordneten
Systemen, jedoch nicht für Starkstromnetze und Hochspannungsanlagen.
■
Überschreiten Sie nie die kontinuierlichen Überlastgrenzen der verschiedenen
Meßfunktionen (siehe Spezifikationen) oder andere Grenzen welche auf dem Gerät
markiert sind.
■
Spannungen welche am COM Eingang anliegen können sich auch
auf andere Eingänge übertragen
■
Vorsicht beim Messen von Spannungen >20V
