I’ve just had a Kaisa MA329b Smart Meter fitted. Has anyone been able to find a user manual for this model?
The OVO Engineer said he wasn’t given any information about this meter type, so couldn’t help.

I managed to get some information from Kaifa about a different meter (MA120) which has a similar display/interface to the MA329B. I hope this description might be of use to others with this meter.
To add some information to the image posted by
The display normally scrolls through a number of items with a 10 second delay between each item. The set of items is configurable by the supplier, but the default set is: Current Time, Current Date, +A value , -A value.
+A is the total accumulated number of units (kWh) used from the grid. If you have Economy 7 (dual rates), +A is the total of the peak and off-peak units used.
-A is the total accumulated number of units exported back to the grid (e.g. if you have solar equipment that can export excess solar).
Snipping a part of

L1, L2, L3: show the three phases are active. If you are exporting on one of those phases, the L for that phase will be blinking.
L: This is currently showing Low energy consumption. It could also be M or H for Medium or High consumption. I don’t know what the ranges are for those three bands of consumption.
The “hat” icon: This shows the state of the electricity supply. The version in the image above indicates the supply is on and normal. A version of this icon without the two vertical lines indicates either disconnected, or if flashing, ready to connect.
T1: This is indicating which tariff is in use (see later). The value could be T2 is you have dual rates.
The “hat” icon without the vertical lines before the £ sign: I don’t know what this represents.
£: Currency unit.
J: If on, the meter is connected to the network. If blinking, the meter is joining the network. If the J is replaced by a blinking S, the meter is searching for the network.
->: This can be pointing in a number of directions. Taking
A short press is pressing the key for less than 2 seconds. A long press is greater than 2 seconds.
K1: Short press: 1st press - activate LCD backlight; 2nd press - change from Scroll mode to Menu mode. Each press after this will move the cursor up one line.
K1: Long press: In Menu mode, selects the item being pointed to by the cursor >. Return back to the previous level when cursor is on “Return” item in menu.
K2: Short press: 1st press - activate LCD backlight; 2nd press - change from Scroll mode to Menu mode. Each press after this will move the cursor down one line.
These are the +A and -A readings discussed earlier and that appear during the automatic scroll through items. To read them from the meter:
The 329B is a 3 phase meter so not a common install.
