3. Basic operation and useage
3.1 Display & Operation
3.2 Menu structure
3.3 Home Menu Page
3.4The Device Menu of Setup
After entering the “SETUP”page, through the cursor movement enter the goal to set submenu, then set the
related parameter of the meter.
For example: Pressing 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 voltmeter (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.
4. Outline & Installing Dimension
Packaging & ShippingPackage: 42*23.5*34 CM, 40pcs/CTN, Meter outline Size: 96*96 CM
My products are modularity structure, they may meet varies of demands.
We also provide customized serivce.
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.
