Smallest voltage range that the DT80 can measure

Hi all, I hope that someone could help me to confirm this:

We are about to obtain some sensors that have a very small current signal as output, the larger could be about 30mA (around 3V considering multiplier), and the smaller could be even below 1 millivolt (even using a voltage amplifier).

Considering the information given in page 19 of the Manual (UM-0085-B8-DT8x Users Manual):
"What can the dT80 Measure? Using its analog inputs, the DT80 can directly measure the following: DC voltage (30mV, 300mV, 3V and 30V ranges)"

We fear that the DT80 probably won't be able to register such small voltage scale. Could you please help me to confirm this?
I'd appreciate your reply.

Good afternoon C. Min,

You need to consider the resolution not the range. 1mV is well within the measurement capability of the dataTaker in fact it is over 1000 larger than the minimum resolution of the DT80 range.
The resolution of the DT80 range is 0.00025 mV of the 30 mV range, 0.0025 mV on the 300 mV range and 0.025 mV on the 3 V range.
Please refer to page 378 of the DT80 User manual (UM-0085 - B10) for full details.

Cheers

Roger
