• Overload protection: 600 V DC/600 V AC or 3 × 10 6
V
• Hz (energized for 1 minute)
Current under overload: Steady state 15 mA or less, transient state 0.8 A or less
(DT4221, DT4222)
• Overload protection: 750 V DC/750 V AC or 3 × 10 6
V
• Hz (energized for 1 minute)
Current under overload: 1.5 mA or less (DT4223, DT4224)
• Maximum count for each range: 1100 (1000 for 10.00 mF)
• Auto range movement threshold: 1100 counts or more for upper range,
100 counts or less for lower range.
Switches to the high impedance 1.000 μF range when the test leads
are open, regardless of the range.
