2.16 Precautions to Observe When Performing Measurement
•
Do not apply radio-frequency signals with high voltage (50 KHz or above).
•
For the AC adapter, always use the supplied adapter or the recommended adapter. The rated power of
the AC adapter is 100 to 240 VAC, and the rated power frequency is 50/60 Hz. Do not use it at any other
voltage.
● The operating environment in which B-564 (or B-564SL) and B-565 are mixed is 0 to 45°C.
•
Do not input the voltage that is exceeding the specification of this device.
· If a voltage exceeding the specified value is input, the semiconductor relay in the input section will be
damaged. Never input a voltage exceeding the specified value even for a moment. It will cause the fire.
· Have an enough margin from the specification of withstanding voltage when using this device, it have to
consider a noise and change of the measurement voltage.
· Confirm this device is not broken before the input cable is connected to the input terminal.
· Please take care of the static electricity when the connecting the input cables or the thermocouples.
· Do not touch the tip of thermocouples with bare hand after the thermocouples are connected to the
terminal of this device when the tip of thermocouples is not insulated.
The static electricity of a human body will cause damage to this device.
· Do not put the tip of thermocouples to the object which is containing the static electricity when the tip of
thermocouples is not insulated. The static electricity of object will cause damage to this device.
· Do not put the tip of thermocouples to the object which is containing the leaked high voltage of chassis
or metal etc. when the tip of thermocouples is not insulated.
The leaked high voltage of object will cause damage to this device.
· We recommend that the insulation tape puts on the tip of thermocouples before connecting the
thermocouples to the input terminals.
This will protect this device from the static electricity and the leaked high voltage.
* This applies to all the channels even if channel extension is used.
* When B-564 (or B-564SL) and B-565 are mixed, B-564 (or B-564SL) input specifications are applied to all
channels.
