Question on new inverter reading

My new 1200 watt pure sine wave inverter arrived yesterday. I just hooked it up to a new group 27 deep cycle. the LED read 12.9 volts. I then plugged a fan into it and turned it on. Voltage immediately dropped to 12.6. I then plugged in a 60 watt light bulb and it dropped to 12.4. Five minutes later, it was 12.3.

My understanding is that at 11.9 volts I am 60% discharged and should disconnect the draw and recharge battery.

Do my volt readings seem low or is the LED reading on my converter most likely inaccurate.

In a previous thread, I was told to get a volt meter. Would a dedicated volt meter be more accurate?
