To prevent overload, power to the calibrator is automatically disconnected if a transducer mass
above 70 gram for Type 4294 or 200 gram for Type 4294-002 is mounted on the exciter’s
vibration table.
Use of the calibrator is straightforward. You can attach a transducer to the vibration table using
(see Fig.2.2):
• 10 – 32 UNF Steel Stud YQ-2962
• 10 g Mounting Disc DB-2996 (supplied) for transducers:
– with 3 mm threads
– fitted with Mounting Magnet UA-0642
– mounted with beeswax
Note:
Mounting using adhesive is not recommended.
To switch the calibrator on, press the small button on the side of its housing.
After system adjustment, turn the calibrator off by pressing the button again.
To prolong the battery life, the exciter automatically switches off after approximately
100 seconds.
