Operation Precautions
Before Connecting a Logic Probe to the Measurement Object
DANGER
To avoid electric shock and short circuit accidents or damage to the instrument,
confirm the following:
•
The ground pin in the LOGIC connector (plug) of Models 9320-01 and 9327
Logic Probes is not isolated from the instrument’s ground (common ground).
Use grounding-type polarized power cords for the measurement object and this
instrument, and obtain power from the same mains circuit.
Connecting to different mains circuits or using a non-grounding power cord
may cause damage to the measurement object or this instrument because
of current flow through the logic probes resulting from potential difference
between the grounds of the different wiring systems.
To avoid these problems, we recommend the following connection procedure:

Connect this instrument to the
same outlet as the measurement
object using the (supplied)
grounding polarized power cord.
Connect the measurement object’s
ground to the GND terminal
(functional earth terminal) of this
instrument.
(Always obtain power from the
same mains circuit.)
See “2.5.2 Ground the Functional
Earth of This Instrument” (page
Before Turning the Power Supply On
WARNING
•
To avoid electrical accidents and to maintain the safety specifications of this
instrument, only connect the provided power cord to an outlet.
•
Before turning the instrument on, make sure the supply voltage matches that
indicated on its power connector. Connection to an improper supply voltage
may damage the instrument and present an electrical hazard.
CAUTION
Avoid using an uninterruptible power supply (UPS), DC/AC inverter with rectangular
wave or pseudo-sine-wave output to power the instrument. Doing so may damage the
instrument.
To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it
from the power outlet.
Turn off the power before connecting or disconnecting the power cord.
