If this must be happened under power on situation, please be cautious of electrical shock
In order to prevent the meter from being affected by the battery replacement, this
operation needs to be completed in 30 seconds. The Real Time Clock (RTC) should also be
set thereafter immediately.
2.13 Normal operation mode
When the meters are being installed on site, the terminal cover will be open for wire
connection. Hence, the meters work at the installation mode when meters left factory in
which the meters do not detect the meter cover open and terminal cover open.
After the meters are installed, close the terminal cover then switch the meter modes back
to Normal working via stroking ‘865’ when the detection of meter cover open and
terminal cover open will be activated ( S5 indication disappears). This function cannot
be reversed.
Switch to normal working mode
