3. Select an accelerometer of correct mass and connect to CH2.
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
