is approximately ±7.5 V.
• For the efficiency math function, +5 V represents 100%.
• For Upk and Ipk, ±5 V represents the application of 3 times the rated range value (6 times the rated range
value when the crest factor is 6).
• When the selected output function is “----” or there is no numerical data, the output is 0 V.
