The E470 meter features two push buttons (see Figure 3):

Display button A (green) primarily used for scrolling through configured
menus configured for the meter and selecting functions.

Display button B (grey) used for locally re-connecting the supply and
other display menu functions.
The E470 features a single red colour metrology LED for indicating active
or reactive energy pulses. The pulse constant (number of pulses per en-
ergy unit measured) of the metrology LED and class for active and reactive
measurement is laser etched on the face plate above the metrology LED.
By default, the metrology LED will be set to the following conditions (during
manufacture):

The pulse constant is set as 1000 imp/kW(Var)h (in accordance with
MID Class B; IEC Class 1)

The pulse length is set to 20 ms.
By default, the metrology LED indicates active energy.
Below starting current, the metrology LED is permanently lit to indicate that
the meter is in an 'anti-creep' status and the registers do not increment.
The LED remains lit until the meter current is increased in a forward
direction beyond the starting current.
The E470 meter features a custom segmented liquid crystal display (LCD,
see Figure 5.
