*1
The voltage display is set to RMS in AC/AC+DC mode and AVG in DC mode.
*2
AC mode: For an output voltage of 17.5 V to 175 V / 35 V to 350 V and 23 °C
± 5 °C. DC mode: For an output voltage of 25 V to 250 V / 50 V to 500 V and
23 °C ± 5.
*3
An output current in the range of 5 % to 100 % of the maximum current, and 23
°C ± 5 °C.
*4
An output current in the range of 5 % to 100 % of the maximum peak current
in AC mode, an output current in the range of 5 % to 100 % of the maximum
instantaneous current in DC mode, and 23 °C ± 5 °C. The accuracy of the
peak value is for a waveform of DC or sine wave
*5
For an output voltage of 50 V or greater, an output current in the range of 10 %
to 100 % of the maximum current, DC or an output frequency of 45 Hz to 65
Hz, and 23 °C ± 5 °C.
*6
The apparent and reactive powers are not displayed in the DC mode.
*7
The reactive power is for the load with the power factor 0.5 or lower.
