Logic probe input and 8835-01 share the same GND. Separate power
supply sources applied to the testing device and 8835-01 may result in
risk of electric shock and damage to the unit.
Even with the same power supply source, certain ways of wiring may
cause a variance in electric potential sending current that may damage
testing device and 8835-01. The following shows proper wiring to avoid
damage. For details, see Section 2.5.
(1) Before connecting logic probe to testing device, connect grounded
three-core power cord (attachment) to the device to be tested and
8835-01 and supply power from the same outlet.
(2) Before connecting logic probe to device to be tested, connect GND of
device to be tested with 8835-01 functional ground terminal. Make
sure that power is supplied from the same outlet.
When using grabber clips, the 9322’s maximum rated voltage to earth is
1500 V AC/DC; when using alligator clips, it is 1000 VAC/DC. To avoid
electrical shock and possible damage to the unit, never apply voltages
greater than these limits between the input channel terminals and
chassis, or across the inputs of two 9322s.
Maximum input voltage is 1000 VAC/2000 VDC. Do not measure voltage
in excess of these limitations, as doing so may damage the unit or
cause an accident that might result in injury or death.
CAUTIO
・Use designated connection cables only. Other cables may interfere with
proper connection and measurement accuracy.
・Maximum charge input for miniature connecter terminal in 8947 CHARGE
UNIT is +, - 500 pC (at range 6 high sensitivity) and +, - 50000 pC (at range
6 low sensitivity).
NOTE
WARNIN
To avoid electric shock accident, before removing or replacing an input
module, confirm that the instrument is turned off and that the input
cords and power cords are disconnected.
To avoid the danger of electric shock, never operate the product with an
input module removed. To use the product after removing an input
module, install a blank panel over the opening of the removed module.
Use only the specified connection cord. Using a non-specified cable may result
in incorrect measurements due to poor connection or other reasons.
(5) Replacing the input units (see Section 15.3)
