Operating Precautions
10
• The operating temperature range of the instrument is -10°C to 50°C.
Do not use the instrument in an environment that is out of this range.
• To avoid damage to the instrument, protect it from physical shock
when transporting and handling. Be especially careful to avoid physi
-
cal shock from dropping.
• This instrument may cause interference if used in residential areas.
Such use must be avoided unless the user takes special measures to
reduce electromagnetic emissions to prevent interference to the
reception of radio and television broadcasts.
• Before transporting the instrument, disconnect all cables and remove
any CFcard, USB flash drive and recording paper.
• Do not slant the device or place it on top of an uneven surface. Dropping
or knocking down the device can cause injury or damage to the device.
• The instrument is equipped with a protector. The physical shock pro-
tection provided by the protector does not fully prevent instrument fail-
ures. Be sufficiently careful when handling the instrument.
Correct measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current conduc
-
tors, or in the presence of strong electromagnetic fields such as near
radio transmitters.
Handling the Cords and Cables
To avoid electric shock, do not exceed the lower of the ratings
shown on the instrument and test leads
• Avoid stepping on or pinching cables, which could damage the cable
insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging it from the power outlet.
• When disconnecting the BNC connector, be sure to release the lock
before pulling off the connector. Forcibly pulling the connector without
releasing the lock, or pulling on the cable, can damage the connector.
• To prevent an electric shock accident, confirm that the white or red
portion (insulation layer) inside the cable is not exposed. If a color
inside the cable is exposed, do not use the cable.
