Caution in Handling
When using this amplifier, always follow the precautions below.
1) Users
Users who are not familiar with the operation of this recorder should avoid using it.
2) Use and storage environment
The storage temperature and humidity of the input units is –20 to 70
°
C and 10 to 90%,
respectively. Avoid storing in places where the temperature could rise over the storage
temperature and where there is direct sunlight exposure such as inside an automobile.
Do not use this recorder at the following locations.
1. Locations where the temperature and humidity rise due to direct sunlight or heaters. (The
operating environment of the amplifier; temperature: -10 to 50 °C, humidity: 20 to 85%)
2. Wet locations
3. Locations where salt, oil, or corrosive gases exist
4. Damp or dusty locations
5. Locations subject to strong vibrations
3) Cautions on power supply
1. Be careful of power voltage fluctuations. Do not use the amplifier when these are likely to
exceed the rated voltage.
2. If the power supply includes a lot of noise or high-voltage inductive noise, use noise filters
to avoid operation errors.
4) Calibration
We recommend a periodical calibration to maintain the accuracy. More reliable
measurements are possible by calibrating the amplifier once a year (extra cost option).
