Typical Application
K 6 V, 60 V,
600 V, 1000 V ± 5 % of scale Most signals.
K 600 mV ± 30 mV High-frequency 5 V logic signals. (The dc-coupling of the L function can
attenuate high-frequency logic signals, reducing their amplitude enough to
interfere with triggering.)
mL 600 mV 40 mV Refer to the measurement tips given before this table.
L 6 V 1.7 V 5 V logic signals (TTL).
L 60 V 4 V Automotive switching signals.
L 600 V 40 V Refer to the measurement tips given before this table.
L 1000 V 100 V
