Introduction

Thank you for purchasing the HIOKI “Model 9320/ 9320-01
LOGIC PROBE”. T o obtain maximum performance from the de­vice, please read this manu al first, and keep it handy for futur e
reference.

Overview

The 9320 is a logic probe with ind icator. It is connected to the
logic input unit for the 8800 series Memory HiCorders. It is
equipped with a selector for each channel, so that the input type
can be switched between digital input and contact input for each
channel. This makes it possible to use this probe for a variety of
applications such as measurement of electronic circuits and op­eration timing of mechanical relays .
The 9320-01 is connected to the logic input unit for the 8807/08
MEMORY HiCORDER. The 8 pin connector to lo gic input unit
differs in, from 9320 from 9320-01.
It is possible to use the 9320 for 8807/08 by using optional 9323
CONVERSION CABLE.

Inspection and Maintenance

Initial Inspection

When you receive the devic e, insp ec t it c areful ly to ensur e tha t
no damage occurred during shipping. If damage is evident, or if
it fails to operate according to the specifications, contact your
dealer or Hioki representative.

Preliminary Checks

• Before using the device th e first time, verify that it oper ates
normally to ensure that the no damage occurred during stor­age or shipping. If you find a ny dam age, contact y our dealer
or Hioki representative.

• Before using the device , mak e s ure th at the insulation on th e
probes is undamaged and that no bare conductors are
improperly exposed. Using the device in such conditions
could cause an electric shock, so contact your dealer or Hioki
representative for repair.

Maintenance and Service

• To clean the device, wipe it gently with a soft cloth moistened
with water or mild detergent. Never use solvents such as
benzene, alcohol, a cetone, ethe r, ketones, thinners or g aso­line, as they can deform and discolor the case.

• If the device seems to be malfuncti on ing , con tact yo ur deal er
or Hioki representative.

• Pack the device so that it will not sustain damage during
shipping, and include a desc ription of existing damage. We
cannot accept responsibility for damage incurred during ship­ping.

Safety

This manual contains information and warnings essential for
safe operation of th e de vi ce an d for m ain tainin g i t in safe oper­ating condition. Before using it, be sure to carefully read the fol­lowing safety precautions.

This device is designed to comply with IEC 61010
Safety Standards, and has been thoroughly tested for
safety prior to shipment. However, mishandling during
use could result in injury or death, as well as damage to
the device. Be certain that you understand the instruc­tions and precautions in the manual before use. We dis­claim any responsibility for accidents or injuries not
resulting directly from device defects.

Safety Symbol

In the manual, the symbol indicates particularly impor­tant information that the user should read before using the
device.

The symbol printed on the device indicates that the
user should refer to a corresponding topic in the manual

(marked with the symbol) before using the relevant
function.

The following symbols in this manual indicate the relative impor­tance of cautions and warnings.

Indicates that incorrect operation presents an extreme haz­ard that could result in serious injury or death to the user.

Indicates that incorrect operation presents a significant haz­ard that could result in serious injury or death to the user.

Indicates that inc orrect o peratio n prese nts a poss ibilit y of
injury to the user or damage to the device.

Indicates advisory items related to performance or cor­rect operation of the device.

Overvoltage categories (CAT)

This device complies with CAT I safety requirements.
To ensure safe operation of measurement devices, IEC 60664 estab­lishes safety st andards for various el ectrical envi ronments, c ategorized
as CAT I to CAT IV, and called overvoltage categories. These are de­fined as follows.

CAT I

: Secondary electrical cir­cuits connected to an AC electri­cal outlet through a transformer
or similar device.
CAT II: Primary electric al circui ts
in equipment connected to an AC
electrical outlet by a power cord
(portable tools, household appli­ances, etc.)
CAT III: Primary electrical circuits of heavy equipment (fixed installa­tions) connected di rectly to the d istrib ution p an el, and feeders from t he
distribution panel to outlets.
CAT IV: The circuit from the service drop to the service entrance, and
to the power meter and pri mary overc urrent protec tion devi ce (distribu­tion panel).

Higher-numbered categories correspond to electrical environments
with greater momentary energy. So a measurement device designed
for CA T III enviro nmen ts c an endu re greate r mome ntar y en ergy than a
device designed for CAT II.
Using a measurement device in an environment designated with a
higher-numbered catego ry than that for w hich the devic e is rated could
result in a severe accident, and must be carefully avoided.

Usage Notes

Follow these precautions to ensure safe operation and to obtain
the full benefits of the various functions.

• The main unit's GND and the logic input terminals
GND are not insulated. Handle these ite ms c arefully in
order to avoid electric shock or a short circuit accident.

• The maximum input voltage is 50 VDC. Attempting to
measure voltage in excess of the maximum input
could destroy the device and result in personal injury
or death.

Do not allow the device to get wet, and do not take mea­surements with wet hands. This may cause an electric
shock.

• Do not store or use the device where it could be exposed to
direct sunlight, high temp erature or humidity, or condensa­tion. Under such conditions, the device may be damaged
and insulation may deteriorate so that it no longer meets
specifications.

• This device is not designed to be entirely water- or dust­proof. Do not use it in an es pecially d usty envi ronment, nor
where it mig ht be spl ashed with li quid. This may cause d am­age.

• T o avoid damage to the device, protect it from physical shock
when transporting and handling. Be especially careful to
avoid physical shock from dropping.
