    Displayed contents The KPM1000’s screen shows displays A, B, C, and D, and the status indicators. Displays A, B, C, and D Displays A, B, C, and D show measured values. You can assign different display items to each display. The four displays are divided into two groups: (1) displays A and C and (2) displays B and D.
  • Page 20 Displayed contents Display configuration • Sign display If there is no sign, the value is positive. If “-” is displayed, the value is negative. • Symbol display If “P” is displayed, the value is the positive integrated power. If “n” is displayed, the value is the negative integrated power.
