Basic and Accuracy Specications
Voltage Measurement
AC/DC automatic
detection range
AC detected at 30 V or greater (50 Hz/60 Hz).
(pulsating currents with an overlapping AC component of
30 V or more are detected as AC)
Effect of temperature
Measurement accuracy per 1°C × 0.1
(applied in the operating temperature range excluding
18 °C to 28 °C)
Overload protection
750 V AC (10 s), 750 V DC (10 s)
1200 V DC (10 s) (IR4053 and IR4055 only)
Display update interval Within 1 s
Response time
Within 1.2 s
(when input voltage is changed from 0 V to 600 V)
