According to JAR-25 the maximum tolerance for servo assisted (which I bet these are) altimeters per 100 knots of CAS is +/- 30 ft.

20 ft between any two ADRs and 25 ft between between PFD altitude readout and actual altitude (300ft for stby alt) - beware: elevation of your parking stand and apt elevation may differ.
