Yeah couldn't really find anything on the AGL 'read your own meter' page, but . . .
I have the MK7A fitted as my CL meter, with a separate meter (MK10D) for regular and solar input.
The MK7A meter is always on pulse 2 led, so is just recording CL at the relative times.
If you only have just this meter, you should find pulse 1 led is on all hours outside CL times.
Yours sounds the same (as mine), you have 2 meters and CL hot water ?
I assume if you have single meter and no CL (hot water etc), then yours will probably be on pulse 1 all the time.
