AC5.0 to 300.0V
(45 to 65Hz)
(425V peak or less)
0.0 to 314.9V ±1%rdg±4dgt
DC±5.0 to ±300.0V 0.0 to ±314.9V ±1%rdg±8dgt
*AC measurement method : rms detection
For the waveforms other than sinewave
of CF<2.5, the specified accuracy
±1%f.s. should be applied.
* AC/DC auto-detection at 5V or higher
* DC sign appears at 5V or higher.
(H+S(C+P) terminal: positive side, E terminal : negative side)
* The LCD reads 0.0V for 0.9V or lower voltages.
