Specifications
The accuracy specifications vary depending on usage. The following specifications
indicate the accuracy at an ambient temperature of 23
°
C
±
5
°
C, after performing auto-
calibration, and are applicable for one year after calibration. They do not include
measuring lead parts. The conditions for the temperature factors are 5
°
C or more but
less than 18
°
C, and more than 28
°
C up to 40

*1 If you turn off the EL or stop charging while the EL is on and charging is in progress at the same time, it takes two hours for the
accuracy in that condition to fall within the specified rating.
*2 If the applied output exceeds the maximum output, the output limiter operates. (A manual reset is required.)

*1 SINK: A function extracts the current of the specified value in the direction of the Hi terminal from an external voltage generating
source (up to 28 V).

*1 Resistance Generation: The equivalent resistance generation system from detecting the resistance measurement current and the
generating voltage drop. The specifications are valid within the measured current and voltage shown in the remarks column.
*2 If you turn off the EL or stop charging while the EL is on and charging is in progress at the same time, it takes two hours for the
accuracy in that condition to fall within the specified rating.
