STM32L100C-Disco board standby mode

When using the STM32L100C-Disco Board i use the command,

HAL_PWR_EnterSTANDBYMode()

but when I measure the current on I_DDpins using a multimeter on the uA setting (using a Fluke 87), I read a value of ~282uA, which is higher than the spec sheet which says ~3uA. Any ideas why?  Are there additional commands that need to be called prior to entering standby mode?  Could it be the type of multimeter I am using?  I disable the wakeup pins and I made all the pins Analogue inputs before entering standbymode.
