Hand-held Probe
With the probe TRX-17 attached, the vibration trans-
ducer can be used as a hand-held probe. The probe
can be fastened directly to the transducer TRV-12.
Hand-held probes are widely used for quick vibration
surveys. The advantages are obvious - there is no
need to prepare measuring points. Note, however,
that the overall stiffness is poor, which can give gross
measuring errors. Using a hand-held probe requires
practice and repeatable results cannot be guaran-
teed.
Taking Readings
Connect the transducer to Vibrameter VIB-11 with the
measuring cable. Attach the transducer to the meas-
uring point.
Press the button below the display window and hold
it down. Wait for the readout to stabilize. Read and
record the result.
To switch off the instrument, release the button.
If the display shows "
OFL
", the instrument has an
overflow, caused by signals above the masuring range.
Changing Batteries
The display will show "
Lob
" when the battery voltage
is getting low.
Use a coin to give both locks of the battery compart-
ments a quarter turn to the right or left. Insert new
batteries as shown on the back of the instrument.
Use only alkaline battery cells, 1.5 V, for example MN
1500 or UCAR E91. Leaking batteries can destroy the
instrument. Remove the batteries before storing the
vibrameter for long periods.
