2.
Connect the hammer to connector A.
3.
Select an accelerometer of correct mass and connect to connector B.
4.
Place the accelerometer on mass.
The mass can be hand-held. The use of foam or a supporting structure is
not necessary.
5.
Set the Measurement parameter to Apparent Mass.
6.
Set the Meas Units parameter to N/m/s2.
The instrument displays 1 kg (or other chosen mass), plus the weight of the
accelerometer:
M = calibrated mass + accelerometer mass
For example: 1 kg + 10.5 g = 1.0105 kg
