Electrical Characteristics
Maximum rated
current between
terminals
• DT4252, DT4256: Current terminal (A): 10 A DC/10 A AC
• DT4253: Current terminal (µA, mA): 60 mA DC
Maximum rated
voltage between
measurement
terminals and
ground
1000 V AC (Measurement category III)
600 V AC (Measurement category IV)
Anticipated transient overvoltage: 8000 V
Rated power
voltage
1.5 V DC × 4
LR03 Alkaline battery × 4
Maximum rated
power
600 mVA
(Power voltage 6.0 V, continuity measurement input
short-circuited, backlight lit)
Rated power • 36 mVA +20% or less
(Power voltage 6.0 V, DCV measurement, backlight off
)
• 12 mVA +20% or less
(Power voltage 6.0 V, sleep mode)
Continuous
operating time
Approx. 130 hours when backlight is off and LR03
alkaline batteries x 4 is used. (at 23°C)
Circuit protection
(Only the DT4255)
Current-limiting resistance, protective fuse
Even when the internal circuit is damaged and short
circuit occurs, the short circuit current is controlled
using the current-limiting resistance, and the circuit is
shut off using the fast-blow fuse.
