Overvoltage Categories (CAT)
This instrument complies with CAT II safety requirements. This instrument’s
input modules com ply wi th CAT I or CA T II sa fety r equirem ents. T o en sure sa fe
operation of measuremen t instr uments, IE C 60664 es tablish es saf ety standa rds
for various electrical env ironments, catego rized as CAT I to CAT IV, and ca lled
overvoltage categories. These are defined as follows.
CAT I Secondary electrical
circuits conn ected to
an AC electric al outlet through a transformer or similar
device.
CAT II Primary electri cal cir -
cuits in equipment
connected to a n AC
electrical outlet by a power cord (portable tools, household appliances,
etc.) CAT II covers directly measuring electrical outlet receptacles.
CAT III Primary electrical circuits of heavy equipment (fixed installations) con-
nected directly to the distribution panel, and feeders from the distribution
panel to outlets.
CAT IV The circuit from the service drop to the service entrance, and to the
power meter and primary overcurrent protection device (distribution
panel).
Higher-numbered cate gories correspond to electrical enviro nments with greater
momentary energy. So a measurement device designed for CAT III environments can endure greater momentary energy than a device designed for CAT II.
Using a measurement instrument in an environment designated wit h a highernumbered category th an that for which the in strument is rated c ould result in a
severe accident, and must be carefully avoided.

• To avoid breaking the cords, do not bend or pull them.
Use only the specifi ed connection cords. Using a non-sp ec ifi ed c ab le m ay re su lt
in incorrect measurements due to poor connection or other reasons.
• Always hold the disc by the edges, so as not to make fingerprints on the disc or
scratch the printing.
• Do not wet the disc with volatile alcohol or water, as there is a possibility of the
label printing disappearing.
• To write on the disc label surface, use a spirit-based felt pen. Do not use a ballpoint pen or hard -tipped pen, becau se there is a d anger of sc ratch ing the surface and corrupting the data. Do not use adhesive labels.
• Do not expose the disc directly to the sun's rays, or keep it in conditions of high
temperature or humidity, as there is a danger of warping, with consequent loss
of data.
• To remove dir t, dust, or fin gerprin ts from the disc , wipe with a dry cloth, or use
a CD cleaner. Always wipe radially from the inside to th e outside, and do no
wipe with circular movements. Never use abrasives or solvent cleaners.
• Hioki shall not be held liable for any problems with a PC syste m that arises
from the use of this CD , or for any probl em related to the purchase of a Hi oki
product.

2.1 Install an input module
Input modules specified at the time the instrument is ordered are supplied preinstalled. Use the following procedures to add or replace input modules, or to remove them from the instrument.
Preparations
• To avoid ele ctric shock accident, before remo ving or replacing an input module, confirm that the instr ument i s turned o ff and that the con nection c ords ar e
disconnected.
• The mounting screws mus t be firmly tightened or the input module may not
perform to specifications, or may even fail.
When an input module is not used
• To avoid the d anger of electric shock, never operate th e instrument with an
input module removed. To use the instrument after removing an input module,
install a blank panel over the opening of the removed module.
• To avoid dam aging input modules , do not touch the inp ut module connecto rs
on this instrument.
• Measurements made without a blank panel installed may fail to meet specifications because of temperature instability within the instrument.
For information on analog channel accuracy when using logic channels, see
"8.10 Making Detailed Settings for Input Modules" ( p.14 0).

2.2 Connecting Cords
2.2 Connecting Cords
When measuring analog signals
Connect the cables or sensors to the input module.
When measuring logic signals
Connect the logic probe(s) to the LOGIC terminal(s) on th e instrument.
When measuring power line voltage
• The connection cords should only be connected to the secondary side of a
breaker, so the breaker can p revent an ac cident if a short c ircuit oc curs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs.
• When connectin g cl ip- ty pe te st le ads to live terminals, be ve ry ca reful to avoid
accidentally shorting conductors together and causing a serious accident.
• To prevent elec trical sh ock and pers onnel injur y, do not touch any input terminals on the VT (PT), CT or the instrument when they are in operation.
• Do not permanently connect the device in an environment where voltage
surges exceeding th e maximum input voltage may occur. Failure to observe
this precaution could result in damage to the device and personal injury.
Connecting to the BNC jacks on input modules
When disconnecting the BNC connec tor, be sure to release the lock be fore pulling off the connector. Forcibly pulling the connector without releasing the lock, or
pulling on the cable, can damage the connector.
For voltage
To prevent an electric shock accident, confirm that the white or red portion (insulation layer) inside the cable is not exposed. If a color inside the cable is
exposed, do not use the cable.
Use only the specif ied c onn ec tio n c or ds . Usi ng a non -s pe ci fie d c able may result
in incorrect measurements due to poor connection or other reasons.
For temperature measurement
When connecting a thermocouple using a wire run of mor e than 3 meters, the
EMC environment in cluding possible influen ce of external noise mu st be taken
into consideration.
For detailed precautions and instructions regarding connections, refer to the documentation of input modules, co nnec ti on cords, etc.
