1000 V (±50 V to ±1000 V)*
Maximum display count for all ranges: 1200/1700 counts
*1 Frequency range of 15 Hz≤f<20 Hz is designed value.
Within the frequency range of f<45 Hz, the accuracy guarantee assumes a superposed DC voltage of less
than 500 V.
*2 Values of up to ±1200 V are displayed, but accuracy is not defined for display values in excess of 1000 V
(which are provided as reference values).
*3 Values of up to ±1700 V are displayed, but accuracy is not defined for display values in excess of 1000 V
(which are provided as reference values).
