1.2.1. The Indicators
Table 1-1-: Kilo, Mega and Negative Indicators
M
Mega
: When lit, indicates that the reading is in Mega, (10^6). 10,000K is shown as
10.00M. 1.0 M is displayed as 1000K.
When Kilo and Mega are both glowing, the reading is in
Giga
(10^9). 10,000M is
shown as 10.00G. 1.0G is shown as 1000M.
Neg
:
-
When lit, indicates that the reading is negative Per IEEE 100 and industry
standard practice by meter men, the following are Negative:
•
With Forward Flow of Watts: Capacitive (Leading) VARs & PF.
•
With Reverse Flow of Watts: Inductive (Lagging) VARs & PF and Watts.
K
Kilo
: When lit, indicates that the reading is in Kilo (10^3). 10,000 is shown as
10.00K. 1.0K is shown as 1000.
Table 1-3: Giga, Mega (M), Kilo (K) & Decimal Point Scaling
RMS Reading
Indicator
Less than 0.001 K, M Off, displays “0.000”
Less then 9999 K, M indicators Off
Above 9999
K ON
Above 9999 k M ON
Above 9999 M Giga (K + M indicators ON)
Upto 9999G
Giga
Above 9999G Display shows “Hi” for +ve numbers and “Lo” for –ve numbers
RMS readings are 4 digits. Energy readings have eight digits, including four additional fractional
digits. The maximum number the Meter handles is 9,999 G for RMS and Energy values.
This means that the Energy readings of the meter will overflow between approximately 2 months
to 3 years depending upon the PT and CT ratios programmed. See Table 2.6 “
Integrator Overflow
