WARNINGS AND PRECAUTIONS

NOTE: The symbol W on the front panel of the multimeter is an international sym-
bol meaning "REFER TO OPERATING INTRUCTIONS. " Warnings and precautions to
avoid personal injury and multimeter damage are listed in this section and in section
"Operating Instructions ".
All inputs are protected against continuous overload conditions up to the limits
'of each function's stated input protection (see Specifications). It is very important
that you make yourself familiar with these specifications. Never exceed these limits !
(1500VDC,1000VAC for DC and AC Volts and 60OVDC or AC for all other functions
and ranges.) All voltage and resistance ranges are protected against voltage tran-
sients up to 6kV, 10µs duration. Current inputs are fuse-protected. Never attempt
to measure voltages or currents that may exceed the ratings marked on the
Function/Range Switch or terminal overlays, or the max. voltage rating above earth
ground. Always use extreme caution when working near high voltage sources,
especially when using the two highest VAC or VDC ranges. High voltages can be
lethal and high voltage transients may occur at any time. Operator injury or dam-
age to the multimeter may occur during current measurements if the fuse blows in a
circuit which exhibits an open circuit voltage greater than 600 volts. Always
inspect test leads, connectors, and probes for cracks or breaks in the insulation
before each use. If any defects are found, replace item immediately. Never touch
test leads, tips, or the circuit being tested while power is applied to the circuit being
measured. Isolate yourself! When measuring current, check that the multimeter is
connected in series with the load in which the current is to be measured. NEVER con-
nect the multimeter ACROSS a voltage source. Please do not use this or any piece
of test equipment without proper training. 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). Please refer
to your CRT service manual for proper servicing instructions.

Überschreiten Sie nie die kontinuierlichen Überlastgrenzen (1500VDC, 1000VAC
für Gleich- und Wechselspannung und 600VDC or AC für alle andere Funktionen
und Bereiche) oder andere Grenzen welche auf dem Gerät markiert sind. Außerste
Vorsicht beim Messen von hohen Spannungen (<30V) wenn bei Strommessung die
