to ensure its correct and safe operation. If used other than as instructed in this
manual, Yokogawa Meters & Instruments Corporation is not liable for any
damage that may result.
The following safety symbols are used on the instrument and in the manual:
Danger! Handle with Care.
This symbol indicates that the operator must refer to an explanation in the
manual in order to avoid risk of injury or loss of life of personnel or damage
to the instrument.
This symbol indicates a direct current.
This symbol indicates a power source.
Warning
Indicates a hazard that may result in the loss of life or serious injury of the user
unless the described instruction is abided by.
Caution
Indicates a hazard that may result in an injury to the user and/or physical dam-
age to the product or other equipment unless the described instruction is abided
by.
Note

IM CA150E
Be sure to comply with the following safety precautions. Failure to do so may
result in loss of life or injury to personnel from such hazards as electrical shock,
or damage to the instrument.
Warning
●Prohibition of Use in Gaseous Environments
Do not operate the instrument in the presence of inflammable and explosive
gases or vapors. Operating the instrument in such an environment is extremely
hazardous.
●Protection Feature Defects
Do not operate the instrument if a fuse or other protection feature is defective.
Before commencing operation, make sure that protection features are free from
defects.
●External Connections
When connecting the instrument to the object to be tested or an external con-
trol circuit, or if you need to touch any external circuit, turn off the power to the
circuit and make sure that no voltage is generated.
●Fuses
To prevent a fire, be sure to use fuses with the specified ratings (voltage, cur-
rent, and type). Do not short-circuit the fuse holder.
●Correct Use of Lead Cables
Be sure to correctly use the measurement lead cables (model: RD031) and source
lead cables (model: 98020) without mistaking them.
●Removing the Casing
Removing the casing and disassembling or modifying the instrument is strictly
prohibited. Some parts inside the instrument are extremely dangerous because
they use a high voltage. When the instrument needs an internal inspection or
calibration, contact Yokogawa Meters & Instruments Corporation or the dealer
from whom you purchased the instrument.
To use the AC adapter (optional) safely, be sure to comply with the following
precautions.
Warning
●Power Supply
Make sure that the rated power supply voltage of the instrument matches the
voltage of the power supply before turning on the power.

3.1 Usage Precautions
Safety Precautions
●Before using the instrument, be sure to thoroughly read "Safety Precautions"
on pages 4 and 5.
●Do not remove the casing from the instrument.
Some parts inside the instrument are extremely dangerous because they use
a high voltage. When the instrument needs an internal inspection or
calibration, contact Yokogawa Meters & Instruments Corporation or the
dealer from whom you purchased the instrument.
●In the case of an abnormality
If the instrument begins to emit smoke, give off an unusual odor, or show any
othersigns of an abnormality,immediately turn off the powerswitch. If you are
using an AC adapter, unplug the power cord from the outlet. Also turn off any
object under test that is connected to the input terminals.
●AC adapter and power cord
Use the designated AC adapter. Do not place anything on the AC adapter or
power cord, and prevent heat sources from coming into contact with them.
When unplugging the power cord from the outlet, be sure to hold the plug and
never pull the actual cord. If the power cord is damaged, contact your dealer.
General Handling Precautions
●When carrying the instrument
Turn off the power to the object under test. Turn off the power to the
instrument and unplug the power cord from the outlet if you are using an AC
adapter. Then, disconnect all lead cables from the instrument. When carrying
the instrument, use the carrying case.
●Keep input terminals away from electrically charged articles as they may
damage the internal circuitry.
●Do not allow volatile chemicals to come into contact with the casing or
operation panel. Also, do not allow the instrument to come into contact with
any rubber or vinyl products for prolonged periods. Since the operation panel
is made of thermoplastic resin, be careful not to let it come into contact with
any heat sources such as a soldering iron.
●Before cleaning the case and operation panel, make sure that the power cord
is unplugged from the outlet if you are using an AC adapter. Dampen a clean
soft cloth with water and gently wipe the surface of the casing and panel.
Water getting inside the instrument may result in a failure.
●If the AC adapter will not be used for a prolonged period, unplug the power
cord from the outlet.
●For precautions on handling dry batteries, refer to "3.2.1 Using Alkaline
Batteries."
●Do not use the instrument with the cover for the battery holder left open.

3-2 IM CA150E
Operating Environment
Use the instrument in locations that meet the following conditions:
•Ambient temperature and humidity
Ambient temperature: 0 to 40C
Ambient humidity: 20 to 80% RH (no condensation)
Do not use the instrument in the following locations:
•In direct sunlight or near heat sources
•Where there is a lot of mechanical vibration
•Near noise sources such as high-voltage equipment or power lines
•Near strong magnetic field sources
•Where an excessive amount of greasy fumes, steam, dust, or corrosive
gases are present
•In an unstable place
•Where, for example, fire and explosions caused by inflammable gases and
the like are possible
Note
•When you require high source and measurement accuracy, use the instru-
ment under the following conditions:
Ambient temperature: 23 5C
Ambient humidity: 20 to 80% RH (no condensation)
When using the instrument in an ambient temperature range of 0 to 18C or 28
to 40C, add the temperature coefficient specified in "11. Specifications" to
the accuracy.
•When using the instrument in ambient humidity of 30% or less, use an anti-
static mat to prevent static electricity.
•Condensation may occur if the instrument is moved from a location of low
temperature and humidity to a location of high temperature and humidity, or if
the temperature otherwise changes suddenly. In such a case, leave the instru-
ment for at least one hour to ensure it is free from condensation before start-
ing operation.

alkaline battery holder.
3Insert the six alkaline batteries into the holder.
4Insert the holder into the opening on the instrument.
5Slide down the lock switch to fix the holder in place. (The lock switch
indication changes to "䉭FREE.")
