Transducer type SPM 40000/42000/44000 is added automati-
cally in the register and can not be edited or deleted. The instru-
ment can also work with SPM DuoTech transducers and any other
transducer of IEPE (integrated electronic piezoelectric) type with
voltage output. Transducers of not IEPE type which do not require
power supply, like velocimeters, can also be used. The ‘IEPE type’
has then to be set to ‘No’.
To register a new transducer, open ‘Settings’ with SHIFT+F3. Se-
lect ‘Transducers’ (1) to open the register (2).
Select ‘New’ (3) with the F1 key, then input the following data.
Press F1 to save the settings and close with the BACK key.
The min. and max. bias voltage (5) is needed for the TLQ
test (Transducer Line Quality test, returning ‘TLT error. Bias
value out of range’ when the measured voltage is above the
max. bias voltage or below the min. bias voltage.
The actual sensitivity of the individual transducer is writ-
ten on its calibration card. This data should always be input
in the transducer register. When several transducers are in
use, they should be marked to assure that the readings are
calibrated.
Name: A descriptive name. It will be shown
on the list of transducers.
Input type: Type of transducer; vibration
transducer, DuoTech or user defined.
Setup of user defined (4), see page
A:16.
Type: The measured vibration parameter,
either ACC (acceleration), VEL
(velocity) or DISP (displacement).
Sensitivity: The transducer’s nominal sensitivity
in the displayed unit (which depends
on the input under ‘Type’). Select
‘User defined’ (4) for other types of
transducers, eg. current clamp.
Max. frequency: The transducer’s upper frequency
range.
IEPE type: YES or NO. ‘Yes’ opens the next
three lines.
Min. bias range: The lower working voltage.
Max. bias range: The upper working voltage.
Settling time: Stabilizing time for the transducer
after ‘power on’.
