I would get funny readings and then go back after the charger cooled then it would read fine like something that window with needle is getting stuck or hung up at times.
The small chargers like that can't run a continuous charge at the higher settings because there's no cooling fan. At 20 amps (or 30 on some models) it will operate for just a couple minutes before the thermal switch trips for a cool-down cycle. In 50 amp start mode it will trip in less than 15 seconds.
You'll have to run at 10 amps for continuous use or get one like HRPC posted that has a fan in it for use at 40 amps.
