*15 RMS, average (AVE), and power (W) are derived using the following equations.
RMS (true rms computation) = ( Σ (square of the instantaneous voltage or instantaneous current)/ the number of samples.)
AVE = (instantaneous voltage or instantaneous current)/the number of samples
WAC = Σ (instantaneous voltage x instantaneous current)/the number of samples
WDC = VAVG x IAVG
•Sample period: 100 ms to 125 ms for AC output (an integer multiple of the output waveform period. 125 ms for DC output.
•Update interval: Approx. 3 times/s, averaging over 2s when averaging is turned on.
•Peak current value holds the maximum value of the absolute value of the peak current for 0.3s or approximately 5s.
•The voltage display is set to RMS in AC mode and AVE in DC mode.
*16 AC mode: For an output voltage of 13.5 V to 155 V/27 V to 310 V and 23°C ± 5°C.
DC mode: For an output voltage of 19 V to 219 V/38 V to 438 V and 23°C ± 5°C.
*17 For waveforms with a crest factor of 3 or less. At 5 % to 100 % of the maximum rated current, 23°C ±5°C
*18 For an output voltage of 50 V or greater, an output current in the range of 10 % to 100 % of the maximum rated current, a load power factor of 1, an output frequency of 45 Hz to 65 Hz or DC, and 23°C ± 5°C.
