Connect Cables Correctly
This instrument can measure large voltages and currents directly. If you use a voltage
transformer or a current transformer together with this power meter, you can measure even
larger voltages or currents. When you are measuring a large voltage or current, the power
capacity of the item under measurement becomes large. If you do not connect the cables
correctly, an overvoltage or overcurrent may be generated in the circuit under measurement.
This may lead to not only damage to the instrument and the item under measurement, but
electric shock and fire as well. Be careful when you connect the cables, and be sure to check
the following points.
Before you begin measuring (before you turn the item under measurement on), check that:
• Cables have been connected to the input module’s terminals of this instrument correctly.
• Check that there are no voltage measurement cables that have been connected to the
current input terminals.
• Check that there are no current measurement cables that have been connected to the
voltage input terminals.
• If you are measuring multiphase power, check that there are no mistakes in the phase wiring.
• Cables have been connected to the power supply and the item under measurement correctly.
Check that there are no short circuits between terminals or between connected cables.
• The current measurement cables are fixed to the current module with a cable strap.
During measurement (never touch the terminals and the connected cables when the item
under measurement is on), check that:
• The input terminals are not abnormally hot.
• The cable strap fixing the current measurement cables to the current module is not loose.
Safety Precautions

xii IM PX8000-03EN
After measuring (immediately after you turn the item under measurement off):
After you measure a large voltage or current, power may remain for some time in the item
under measurement even after you turn it off. This remaining power may lead to electric
shock, so do not touch the input terminals immediately after you turn the item under
measurement off. The amount of time that power remains in the item under measurement
varies depending on the item.
Accessories
Use the accessories specified in this manual. Moreover, use the accessories of this product
only with Yokogawa products that specify them as accessories.
Do not use faulty accessories.
Precautions to Be Taken When Using the Probes
Be sure to connect the GND lead of the high voltage differential probe (the 701926) to the
functional ground terminal of the PX8000. High voltage may appear at the BNC of the high
voltage differential probe. Also, be sure to connect the GND lead to the PX8000 before you

Après la mesure (tout de suite après avoir mis l’appareil mesuré hors tension) :
Si vous avez mesuré une tension ou un courant élevé, une puissance résiduelle peut rester
un certain temps dans l’appareil mesuré, même après sa mise hors tension. La puissance
résiduelle peut entraîner un choc électrique, par conséquent, après avoir mis l’appareil
hors tension, il convient d’attendre avant de toucher les bornes d’entrée. La durée pendant
laquelle la puissance résiduelle reste dans l’appareil mesuré varie selon les appareils.
