2. Mount the accelerometer on the measurement object (for recommend-
ed methods, see the accelerometer instruction manual).
3. Keep the 2010 as far away as possible from the vibration environment
and any other unwanted influences.
4. With the OUTPUT SECTION ATTENUATOR in
"x
1" position,
adjust the INPUT SECTION ATTENUATOR until a suitable deflec-
tion is obtained without any indicated overload. If the deflection is
insufficient, even when the INPUT SECTION ATTENUATOR is in its
10 mV range, then adjust the OUTPUT SECTION ATTENUATOR.
If the INPUT OVER LOAD light flashes, turn the INPUT SECTION
ATTENUATOR switch to a higher range.
If the OUTPUT OVERLOAD light flashes, turn the OUTPUT SEC-
TION ATTENUATOR switch to a higher range.

4.4. SELECTIVE MEASUREMENTS
For selective sound, vibration or voltage measurements between 2 Hz and
200kHz using a selected bandwidth and effective averaging time, the
procedure is as follows:

1. Carry out the appropriate calibration procedure as described in sec-
tion 3.2.
2. Connect the appropriate transducer and preamplifier to the 2010.
3. Set the controls as follows:
