34401A can't measure DC Current

Hi guys,
I have problem with my Multimeter Agilent 34401A. 
I would like to measure DC Current on multimeter. It is connected between PSU (Agilent E3531A or Agilent E3648A) and my device (4.8V). but my multimeter shows . Consequently, my device can't boot.
However, it worked fine before.

To be sure, that my setup is fine, I've connected Handheld Digital Multimeter (Agilent U1271A True RMS 4 1/2 Digit) instead of Multimeter Agilent 34401A. It measures current and my device could boot.

Do you have any idea what should I do? Did I blow a fuse?

Commands which I send to:
*PSU*
+SOUR:VOLT 4.8+
+SOUR:VOLT?+
++4.80000000E+00+
+APPLY?+
+"4.800000,5.000000"+
+OUTPUT ON+

*MULTIMETER*
CONF:CURR:DC 1,MAX
-> SAMP:COUNT 10
-> READ?
