6 kV crest (0.5 s - 100 kHz)

3 kA crest (8 × 20 s)

6 kV crest (1.2 × 50 s)

Models Mounting position effects

3051C Zero shifts up to ±1.25 inH

O (3,11 mbar), which can be calibrated out. No span effect.

3051CA, 3051T Zero shifts up to ±2.5 inH

O (6,22 mbar), which can be calibrated out. No span effect.

3051L

With liquid level diaphragm in vertical plane, zero shift of up to ±1 inH

O (2,49 mbar). With

diaphragm in horizontal plane, zero shift of up to ±5 inH

O (12,43 mbar) plus extension length on

extended units. All zero shifts can be calibrated out. No span effect.
