Measure current with Keithely 2110

Hi,

I'm trying to measure current with a Keithley 2110 Multimeter (LabVIEW 8). The current in sleep mode is around 3uA and has a peak at 9mA and with 0.1ms width, I would like to capture the pulse and especially the peak.
I am sending SCPI command in my LabVIEW code, I have set the NPLC to 0.001, turn off the Auto range. I read from the datasheet that the device is capable of max 50000 readings/sec, I read also that the AMP:COUN 50000 is the number of sampling between tow trigger, but I can't figure out how to configure the trigger to achieve the maximum readings per second. Here is the part of SCPI command I am sending :

:FUNC 'CURRC'
:CURR:RANGE:AUTO OFF
:CURR:RANGE 0.01
ENSE:CURR:NPLC 0.001
:TRIGEL:AUTO OFF
:TRIGELAY 0.0
ER:APER 0.01

:TRIGOUR IMM
AMP:COUN 5000
:TRIG:COUN 1
:TRIGEL:AUTO OFF
:TRIGEL 0
:READ?

I appreciate any help.

Thanks.
