说明使用键可按需显示任何测量值。每次按下该键时，都会显示新一页监控值的开始。这些分类为：A1计量、A2状态、A3功率分析、A4产品信息。使用和键在实际值消息之间移动。以下各节详细描述了这些组中显示的每条信息。A:B:C:CURRENT：显示与A、B和C相输入相对应的各相电流。只有输入CT PRIMARY（电流互感器初级）以匹配安装的CT初级，且CT次级接线以匹配1或5 A输入，才能正确测量电流。如果显示的电流与实际电流不匹配，请检查此设置点和接线。
Description Any measured value can be displayed on demand using the key. Each time the key is pressed, the beginning of a new page of monitored values is displayed. These are grouped as: A1 METERING, A2 STATUS, A3 POWER ANALYSIS, A4 PRODUCT INFO. Use the and keys to move between actual value messages. A detailed description of each displayed message in these groups is given in the sections that follow.A: B: C: CURRENT: Displays the current in each phase corresponding to the A, B, and C phase inputs. Current will be measured correctly only if the CT PRIMARY is entered to match the installed CT primary and the CT secondary is wired to match the 1 or 5 A input. If the displayed current does not match the actual current, check this setpoint and wiring.
