Testing the Installation

Verify Voltage:
Characters are always displayed on the LCD when the meter has proper power
on L1 and neutral (See Section 4.1 for a description of LCD screens).
Verify Energy:
Before checking energy direction, make sure there is a load drawing a minimum
of 1A connected to the meter.
The LCD has an energy-flow indicator in the lower left section of the display. The
energy-flow indicator points to the right when the meter measures positive energy
(normal) and points left when the meter measures negative energy.
If the arrow is not shown, points to the left or is shown with no pointer in either
direction, there is an installation problem. Refer to Section 6 for troubleshooting
instructions.
Verify Load:
The load LED has a 10Wh pulse rate (5 watt hours on, 5 watt hours off). The duty
cycle should be 50% when the meter is connected properly and a constant load
is applied. Figure 7 shows the appearance of the LCD when the meter is installed
properly.

Table 5 shows the LCD screens in sequence at power up and during normal operation.
The startup screens are displayed only once at power up. From then on, the meter
repeatedly cycles through the runtime screens as described in Table 6. For dual-
element meters, energy, demand and power are shown on the runtime screens as
combined values for Line 1 and Line 2.
