3.3 Home Menu Page
3.4 The Device Menu of Set up A fter e nter ing the “ SETUP ” page , through the cursor movemen t enter the goal to set submenu, then set the related parameter of the meter . For e xample: Press ing the ENTER button to enter into “system parameter” to set submenu, then we may adjust 3 phase ammeter (TA Current Transformer ratio ) or 3 phase volt meter (TV Voltage Transformer Ratio) and the mode of connection . Note: mode of connection "Y" represents 3 phase 4 wire, "the Delta " represent 3 phase 3 wire as below:
As shown above: 3 phase ammeter CT: 100/5A We should input 20A at the position of TA Ratio, then QUIT & SAVE.

6. Attentions 6.1 The following conditions will lead to the device be damage or work abnormal: 6.1.1 The auxiliary power supply, voltage, frequency are over-range. 6.1.2 Please do not treat the PT signal as well as the auxiliary power supply at the same time Unless the PT have enough power, so that the meter can be ensured to work normally. 6.1.3 CT circuit current wiring terminal screws must be tightened, and ensure the inlet / outlet lines are reliable to avoid faults. 6.1.4 If checking meter, the calibration instrumentation should be prior a class 0.1 magnitude, so that the accuracy could be ensured.
