BRUEL & KJAER 2203 Instructions And Applications

1. Mount the Accelerometer on the 4291 and connect to the Integrator
(if required) and the 2203 (Fig .3.1 ).
2. Set the Integrator (if used) to desired function .
3. Pull METER SWITCH out and wait 20 seconds for warm-up.
4. Set METER SWITCH to "Batt." and check battery condition.
5. Set METER SWITCH to "Fast" and "Lin.".
6 . Set Accelerometer Calibrator to "Int. Gen." and then adjust ACC.
LEVEL so the lower scale of the 4291 meter indicates the mass of
the Accelerometer (given on its calibration chart).
7. Set A TTENUATORS of the 2203 for at least 1 /3 full scale deflection.
8. Adjust the ADJ . potentiometer to give a meter deflection of + 7, 0 dB.
9. Note
the attenuator setting inside the red lines and add 10 dB. This
gives the zero reference level in dB (Z) corresponding to 1 g RMS or
any of the following vibration reference amplitudes (R) to which the
2203 is now calibrated depending on the Integrator setting:

1.
Connect the Accelerometer to the Integrator (if required) and the
2203 (Fig.3.1 ).
2.
Set Integrator (if used) to desired function.
3. Pull METER SWITCH out and wait 20 seconds for warm-up .
4. Set METER SWITCH to "Batt." and check battery condition .
5.
Set METER SWITCH to "Fast" and "Lin." .
6. Set ATTENUATORS so "Ref." is inside the red lines.
7. Set ADJ. potentiometer for K-factor of zero for Integrator ZR 0020,
+ 0,8dB for JJ 2614, and+ 1,2dB for JJ 2615 .
