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.
