6.4.3
“BT” Interface, i.e. RS485 Communication Baud Rate Setting Interface
This interface displays the present communication baud rate, whose default is “9600” and can be
set as 9600, 4800, 2400, 1200. After setting, press button “
” to confirm and enter “UL” interface.
6.4.4
“UL” Interface, i.e. Voltage Wiring Mode Setting Interface
There are 2 options for the voltage wiring modes, i.e. “3Ln” referring to 3-phase 4-wire wiring mode;
and “2LL” referring to 3-phase 3-wire wiring mode. After setting, press button “
” to confirm and
enter “IL” interface.
6.4.5
“IL” Interface, i.e. Current Wiring Mode Setting Interface
There are 2 options for the current wiring modes, i.e. “3C” referring to 3 CTs used for current wiring;
“2C” referring to 2 CTs used for current wiring to calculate phase B current in three-phase balanced
environment (some model numbers don’t support this option). After setting, press button “
” to
confirm and enter “F5” interface.
6.4.6
“PT” Interface, i.e. PT Ratio Setting Interface
This interface displays the present PT ratio, whose value ranges from 1 to 2000. After setting, press
button “
” to confirm and enter CT ratio setting interface.
For example, if the PT ratio is 10KV/400V, the PT ratio will be 25, that is to divide 10,000 by 400.
Setting examples:
If the PT ratio is 10kV/400V, the PT ratio will be 25, that is to divide 10,000 by 400.
Remark:
The product of PT ratio and CT ratio is not more than 300,000.
6.4.7 “CT” Interface, i.e. CT Ratio Setting Interface
This interface displays the present CT ratio, whose value ranges from 1 to 1000. The setting methods
are as follows. After setting, press button “
” to confirm and enter RE1 interface, the relay interface
(some model numbers don’t support this option).
6.4.8
Press button “
” and “
” simultaneously at any setting interface, it will exit the setting
interface and switch back to the parameter display interface.
6.4.9
Press button “
” , button “
” and “
” simultaneously to enter password inquiry interface.
Enter meter password, whose default is “0000”. After setting, press button “
” to confirm and enter
“ST” interface. If the password is not correct, it won’t enter “ID” interface
