08/2010 Chapter 1 – PM1000 Series Power Meters Product Description

The Indicators – Kilo, Mega, and Negative

Table 1-2 Indicators

Kilo: When lit, indicates that the reading is in Kilo (10

). 10,000 is displayed

as 10.00 K and 1.0 K as 1000.

Mega: When lit, indicates that the reading is in Mega, (10

). 10,000 K is

shown as 10.00 M. and 1.0 M as 1000 K.

Giga: When Kilo and Mega are lit together, the reading is in Giga (10

10,000 M is shown as 10.00 G and 1.0 G as 1000 M.

Negative: When lit, indicates that the reading is negative as per IEEE 100

and industry standard practice by meter-men:

When PF (power factor) is lead (capacitive load): Both PF and VAR

(reactive power) sign will be negative. When current is reversed: W (active

power) is negative.

Table 1-3: Giga, Mega (M), Kilo (K), and decimal point scaling

RMS readings are four digits. Energy readings have eight digits, including

four additional fractional digits. The maximum number the power meter

handles is 9,999 G for RMS and energy values.

This means that the energy readings of the power meter will overflow at

three values of Wh (active energy) or VAh (Apparent energy) (selectable

through PROG menu - setup) depending upon the PT (VT) and CT ratios

programmed.
