Measuring categories CAT CAT IV:
.
• Always check voltage testers for correct functioning immediately
before and after use.
• standards-compliant design voltage tester/measuring instru
ment confirmed independent testing and certification institutes
by granting mark conformity (e. 020022

ite no. The
display arranged directly the user's field vision. VDE/GS mark conformity).
• Digital multimeters and current clamps with TRUE RMS measuring
method offer increased accuracy case distorted and non-
sinusoidal signal characteristics industrial use. The measuring inputs must
be marked unambiguously with the measuring category (CAT -
CAT IV) and the maximum nominal voltage earth.t

T tic use_________________________________________
• Always observe the five safety rules for “working under voltage” !
• For determining the absence voltage electrical systems up
to 1000 only use two-pole voltage testers complying with the
current IEC/EN 61243-3 standard. Operating errors due incorrect measuring range
selection are excluded. Thus, incorrect measurements are
excluded!
• Standard-compliant voltage testers must comply least with
protection category 54.
• Voltage testers with connectable load suppress capacitively and
inductively induced voltages.
• Please take into consideration the high-impedance input resistance
(~10 MQ) digital multimeter which indicates capacitively and
inductively induced voltages and which very often might only simu
late the existence voltage.
• DUSPOL® voltage testers are designed for safe working under
voltage. The handles with grip lim offer the highest
safety possible and sufficient distance the measuring object.
• Use digital multimeters and current clamps only for the area ap
plication for which they are designed
