Note
Operating Precautions
- Operate the unit only as described in this manual.
- Do not disassemble or modify the unit.
- In the vicinity of a strong magnetic eld (such as produced by magnets, motors,
speakers, etc.), measurement results may be affected.
- The calibration exciter in the unit uses a semipermanent magnet. If cassette tapes,
oppy disks, watches or similar are placed close to the unit, erasure or faulty opera-
tion may result.
- This is a precision device. Protect it from shocks.
- If the specied torque (0.1 N·m to 0.2 N·m) is exceeded when fastening the vibration
pickup, the exciter spring may sustain permanent damage.
- In case of malfunction, do not any attempt any repairs. Note the condition of the
unit clearly and contact the supplier.
