2.14 Precautions to Observe When Performing Measurement
Please be sure to read the following carefully in order to prevent electric shocks or shorts.
•
Do not apply radio-frequency signals with high voltage (50 KHz or above).
•
Be sure to use only the AC adapter provided as a standard accessory. The rated power supply range for the adapter is
100 to 240 VAC, and the rated frequency is 50/60 Hz. Do not use any other voltages.
•
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 a fire.
– Have enough margin from the specification of withstanding voltage when using this device, it has 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 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.
* The specification of all channels becomes the B-563 (B-563SL/B-563SL-30), when the B-563 (B-563SL/B-563SL-30)
and the B-565 are installed.
CAUTION
When using the Standard terminal (B-563/B-563SL/ B-563SL-30)
Maximum input voltage
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.
< Between +/– terminals (A) >
Maximum input voltage: 60Vp-p (Range of 20mV to 2V)
110Vp-p (Range of 5V to 100V)
<Between input terminal/input terminal (B) >
Maximum input voltage: 60Vp-p
Withstand voltage: 350Vp-p at 1 minute
<Between input terminal/GND (C) >
Maximum input voltage: 60Vp-p
Withstand voltage: 350Vp-p at 1 minute
