Introduction
Thank you for choosing the Hioki P9000-01,P9000-02 Differential
Probe. Preserve this manual carefully and keep it handy to make full
use of this product for along time.
Overview
The product is a differential probe that is connected to a Memory
HiCorder input unit. The probe divides two high voltages input to its
high and low terminals by 100 or 1000 and then outputs the differ-
ence as a signal relative to ground. The P9000-02 includes AC RMS
value output functionality.
Power can be supplied via the optional AC adapter or a commer-
cially available USB cable.
Verifying Package Contents
When you open the package,carefully inspect the product to ensure
that everything is in good condition,and that no damage occurred
during shipping. Carefully check the accessories and connectors.

Measurement categories
To ensure safe operation of measuring instruments,IEC 61010
establishes safety standards for various electrical environments,cat-
egorized as CAT II to CAT IV,and called measurement categories.
WARNING
•Using a measuring product in an environment
designated with a higher-numbered category than
that for which the product is rated could result in
a severe accident,and must be carefully avoided.
•Never use a measuring product that lacks cat-
egory labeling in a CAT II to CAT IV measurement
environment. Doing so could result in a serious
accident.
This product conforms to the safety requirements for CAT III 1000 V,
CAT IV 600 V measuring instruments.
CAT II: When directly measuring the electrical outlet recep-
tacles of the primary electrical circuits in equipment
connected to an AC electrical outlet by a power cord
(portable tools,household appliances,etc.)
CAT III: When measuring the primary electrical circuits of heavy
equipment (xed installations) connected directly to
the distribution panel,and feeders from the distribution
panel to outlets
CAT IV: When measuring the circuit from the service drop to the
service entrance,and to the power meter and primary
overcurrent protection device (distribution panel)
