1. “ Norm ” – in normal operation mode

2. “ Test ” – in test operation mode

3. “ Alt ” – in alternative mode to display messages

4. “ Cali ” – in calibration mode

5. “ Comx ” – in communication mode

6. It displays code of Watt, Volt, Amp, Var, VA, pf, etc. If it is illuminated as “ CA ” or “ AL ”, then caution or alarm status occurs.

7. It displays the value of Watt, Volt, Amp, RMS, Var, VA, pf, etc. Once “ CA ” or “ AL ” is illuminated, the following code is illuminated on these bigger 7 segments too.

Caution codes:

0001: not programmed yet

0002: potential low voltage

0003: received KWH

0004: leading KVARH

0005: overload the demand

Alarm codes:

0001: voltage imbalance

0002: inactive current

0003: under the normal voltage

0004: over the normal voltage

8. “ A ” illuminated means A phase voltage input.

9. “ B ” illuminated means B phase voltage input.

10. “ C ” illuminated means C phase voltage input.

11. “ Cum ” illuminated means it displays cumulative demand value.

12. Both “ Cont ” and “ Cum ” illuminated means it continuously displays cumulative demand value.

13. “ Prev ” illuminated means it displays previous data.

14. “ Max ” illuminated means it displays the maximum demand value.

15. The unit of present displaying value

16. “ El ” illuminated means end of interval time to stop counting the demand value.

17. “→” illuminated means the meter delivers the energy to the loading part.

18. “←” illuminated means the meter received the energy from the loading part.

19. “ Leading ” illuminated means Varh is leading ahead.

20. “ Lagging ” illuminated means Varh is lagging behind.

21. 10 bars is to divide the Kt Watthours by 10 divisions between two pulses.

22 ~ 25. A, B, C, D mean different period time of use applied for different rates. Only one is illuminated at a time.
