To read the EDMI MK7A meter, the following symbols and indicators are used:

- L: Indicates local communication or login on the local port.
- R: Indicates remote communication or login on the modem port. It flashes if connected to the GPRS network in persistent mode with no active login.
- Currency indicator: Present on Mk7 and Mk10A only.
- GMk: Multiplier symbols, where G = Giga, M = Mega, k = kilo. Only "k" is available on Mk7.
- Units: The display can show units such as W, var, VA, Wh, varh, VAh, V, and A.
- Label: Up to 4 seven-segment characters on Mk7 to describe the displayed value.

These symbols help identify the type of data shown on the LCD display.

    Under the Meter Lid Under the Meter Lid Removing the sealable screw allows the meter lid to be removed. Generally connections to the I/O connectors do not need to be detached to allow the cover to be removed. Removal of the meter lid is required to access the Config Jumper, and to add or remove the CT to VT links on meters with old style terminal blocks.

    6-15 Super Cap To eliminate the possibility of data loss it is best to change the battery while the meter is running. Care must be taken as the battery is at the potential of the neutral terminal. The battery is at the potential of the neutral terminal. If conditions (such as wiring configuration) make this a dangerous operation then steps should be taken to ensure that it is safe to do so.
