Why does not start to measure U1241C in AC Amper mode?

I have a U1241C DMM. My problem is with it only measuring AC current in A position. Theoretically it allow 10Amp range with a 0.001 resolution. When I switch to this mode to measure a little current, like a 230V/25W bulb the display shows between 0.001 and 0.002A. The expected value is near to 0.1A. If I make a measurement on a bigger current ( more than 2 Amps with an electrical heater ) and then I try to measure this bulb again the result is ok. It is very annoying behavior. Are there any better solution to make getting to work this instrument ? ( I refreshed the firmware to 1.22. It did not helped. )
