Duet reads 25.4 Vin while multimeter reads 24.7

Just a quick question:
Is it normal for the Duet Wifi (Board version 1.03) to have an inaccurate Vin reading? I measured 24.7v with my trusty mutimeter and another voltage indicator on the powersupply says the same. But according to DWC, Vin is roughly 25.4v.
@nikscha Your multimeter is likely to be correct. Accuracy of the VIN reading is +/-3%, which your reading just about is. Unfortunately, there's no way to calibrate the VIN reading.
