Does anyone use this Druck and can advise?

I am considering the Druck DPI612-PFX-2G pressure calibrator which has a 2 bar pressure module fitted. This would do the majority of our low range instruments. However, I am not sure if I can get the turndown and resolution to calibrate some very low DP cells. These DP cells are typically of the range 0 to 3kpa (gauge). As much as I can get on the instrument is that it has a 6 digit resolution, whatever that means.
Can anyone advise if I can acheive such a low range calibration with this instrument?

The brochure with specs at

states a "total uncertainty for one year = 0.025% FS" for the -1 to 2 bar PM620 pressure module on pg 14 (pdf)

2 bar = 200 kPa
±0.025% of 200 kPa = ±0.050 kPa

Is that good enough?

Thanks, doubt very much if the 2 bar pressure module would do what I need, as it is too large.
