Parameter scrolling: The default display mode is Auto Scroll Mode in which the parameters scroll
automatically. On pressing key, the meter display goes to manual mode. If key press doesn’t happen
for approximately 30 seconds, meter display returns to default mode i.e. Auto Scroll mode.
Push-to-push consumption: The push button is also used for measuring Push-to-Push kWh
consumption. Follow the below steps to measure the Push-to-Push kWh consumption:
a) Scroll through the parameters until Display No.11 (Refer Display Parameters Table 2) is displayed.
b) When Display No.11 is displayed; press and hold the push button, it resets to zero.
c) Energy recording starts in Display No.11.
d) Check Display No.12 to get the energy consumed value between the previous start-&-stop
operations.

WiFi Module DIN Energy Meter
Page 2 of 8
Wi-Fi is one of the most popular wireless communication standards on the market. WiFi
module is used to collect data from L&T make DIN meters through optical interface and to make it
available for the user through WiFi network. The module operates within the ISM 2.400 – 2.484 GHz
frequency band with IEEE802.11b baseband. This WiFi module is compatible with 1 Phase as well
3 Phase meters. The data can be viewed by the user through home page of the module using a web
browser as well as in the user application.
The modes for Wi-Fi connectivity are as follow:
- Infrastructure mode
- Ad hoc Mode
WiFi module is configured in Infrastructure mode as factory default.
Terminal cover to avoid direct contact of the supply terminals along with sealing
provision.
Easy mounting on DIN rail with locking.
Supported network topologies: Ad-hoc and Infrastructure modes
IEEE 802.11b-compliant RF transceiver
Integrated antenna
Range: up to 100m
Supported connections: Open, WEP64, WEP128, WPA, and WPA2.

Mode key helps to configure the WiFi module to infrastructure or ad-hoc mode by pressing it for
1 second .If the same key is pressed for more than 10sec then the module will be configured to
factory defaults. Reset Key resets the module. Power ON LED gives the indication of the selected
mode. Ad-hoc mode will be indicated by the high pulse rate (i.e. 4 pulse/sec). Infrastructure mode
will be indicated by slow pulse rate (i.e. 3 pulses for 5 sec).

Infrastructure mode:
Infrastructure mode is one of the two methods of connecting the module to existing WiFi network
present at home or office with Wi-Fi enabled devices such as laptops, Smart phones etc. These
devices are connected to wireless network with the help of Access point (AP).
Setting Up Infrastructure Mode:
Power ON the meter and module. Configure WiFi router (or any smart device that support WiFi
hotspot) with SSID as “MiEnergyWiFi” and security as “Open”. WiFi module joins with the
