3.2 Liquid Crystal Display Information
The liquid crystal display (LCD) is shown. The numbered list coincides with the numbers in
Figure 3-2.
Figure 3-2: Liquid Crystal Display Information
1. The “TEST” annunciator indicates the meter is in Test mode.
2. The “ALT” annunciator indicates the meter is in Alternate Display mode.
3. The three small digits are used to display the current display label or code. “CA” or
“Er” appearing in this location indicates a Caution or Error message in the display.
4. These letters are used to display the units of measure for the quantity currently
being displayed. For example, energy displays will have a “kW h” annunciator and
Apparent Power will have a “kVA” annunciator.
5. The letters A through D indicate the time-of-use (TOU) rate that is in effect. Only
one letter at a time is displayed when the meter is operating in TOU Mode. If no
letters are lit, the meter is in a non-TOU rate.
6. This display indicates an end-of-interval (EOI) condition.
7. W hen displayed, the “A” annunciator indicates the A voltage is present at the
meter. If this annunciator is blinking, phase-A voltage is low.
The “B” annunciator will only be displayed during an all-segments display.
W hen displayed, the “C” annunciator indicates the C voltage is present at the
meter. If this annunciator is blinking, C voltage is low. (Network meters only)
8. The left-right arrows indicate watt hour direction of energy flow. The right arrow will
be lit if the energy is delivered; the left arrow will be lit if the energy is received.
The up-down arrows indicate VArh direction of quadergy flow. The up arrow will be
lit if the quadergy is lagging; the down arrow will be lit if the quadergy is leading.
The meter’s magnitude indicator consists of three segments, used to simulate the
rotation of the disk on an electromechanical meter. Each state change represents
