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.
