BRUEL & KJAER 2203 Instructions And Applications

3.6.3. With built-in Calibration, Without Integrator
The acceleration level (A) in dB referenced to 1 g is calculated by the
formula
A= M- 94 + 20 log
10
(50/S)
where M is the measured level on the 2203 (dB) and S is the sensitiv-
ity of the Accelerometer in mV /g. A is then converted to accel-
eration units as described in Section 3. 6. 1.
If slide rule QH 0001 is available, the calculation is made as de-
scribed in the next section.
3.6.4. With the built-in Calibration, With Integrator
Slide Rule OH 0001 is used as follows:
1. Set the isolated red line on the inner disc opposite the accelerometer
sensitivity in mV /g.
2. Set the cursor to the measured level on the 2203 on the dB SL scale
and read the vibration amplitude on the scale directly below. Use the
scale corresponding, to the integrator setting. The slide rule cannot be
used
to convert from one vibration parameter to another. To deter-
mine another vibration parameter, new measurements must be made
with a different setting of the Integrator.
