1. Cautionary Notes for Safe Use of the Product
■
The following safety symbols are used on this instrument and instruction manual to ensure safe use.
WARNING
:
This symbol found on the back of the instrument, calls attention to a potential danger or hazard
capable of resulting in a serious injury or loss of life, and the operator must refer to this instruc-
tion manual to avoid the danger or hazard.
WARNING
:
This symbol in this manual indicates a potential danger or hazard capable of resulting in a serious
injury or loss of life.
CAUTION
:
This symbol in this manual indicates a potential danger or hazard capable of resulting in severe but
not irreversible injury or damage. In some instances, the hazards may be those associated with
WARNING symbols but are of significantly less magnitude.
NOTE
:
This symbol draws attention to information that is essential for understanding how to operate the
instrument and/or instrument features.
TIP
:
Gives information that complements the present topic.
■
To avoid accidents, such as an electrical shock, which may lead to injury or the loss of life to the operator,
or damage to the equipment, be sure to observe the following precautions.
WARNING
• Do not use the instrument to measure where there is the risk of electrical shock.
• When handling a needle-type probe, be careful not to point the tip in the direction of any person as doing so may result in an injury.
• After measuring anything with a high temperature, do not touch the metal part of the measuring probe as this may result in a burn.
CAUTION
•
When the instrument is stored for a long period of time, be sure to remove the batteries. Not doing so may result in a failure
or malfunctioning of the instrument due to a leakage in battery liquid.
•
Do not use deteriorated or damaged probes, as doing so will effect the precision of measurements.
•
Before you detach the probe from the instrument, always remove the probe from the object being measured.
•
When using a needle-type probe, do not insert the metal part of the measuring probe more than half its the length into the
object to be measured, as doing so may result in a burn or damage to the probe due to the handle of the probe heating up.
•
Keep the handle of the probe and the cable that connects the probe to the instrument within a temperature range of -20°C to
50°C, as they are less resistant to heat than the metal part of the measuring probe.
■
Regarding Disassembling and Modification
Do not disassemble or modify the instrument in any way. The instrument should only be disassembled by a service engineer of Yokogawa.
2. Functional Description
(3) Check the thermocouple type.
If you wish to change the current setting, turn off the power and follow the instructions in the section Select thermocouple type
on the previous page.
(4) Connect the probe to the input connector.
(5) When you have finished measurement, turn off the power by pressing the
key.
• The power may be turned off by the auto power-off function during measurement. In this case, press the
key to
restart the instrument and continue measurement.
4. Precautionary Notes
NOTE
•
Each probe has its own maximum and minimum operating temperatures, so ensure that its temperature does not fall outside
the specified range.
•
As the probe is susceptible to corrosion, do not use the instrument for the measurement of gas or liquid, and refrain from
measuring semi-solid particles and semi-viscous substances. After measurement, wipe the probe with a dry cloth.
•
Do not apply a strong force to the upper and lower parts of the probe as doing so may result in the bending of the probe connector.
•
When using the instrument be careful not to bend, drop, or strike the measurement probe.
•
When measuring surface temperature using a surface-type probe, position the probe perpendicular to the surface of the object.
Also note that the application of oil to the probe for the means of providing better contact can improve measurement accuracy.
•
When measuring non-metallic surface temperature, make sure the measurement time is long enough to compensate for poor
thermal conductivity.
•
To ensure stable measurement, the instrument should not be subjected to a sudden temperature change.
•
This instrument, with the exception of the connector section, is water-resistant but not waterproof. Therefore the instrument
should not be immersed in water. If it is mistakenly immersed in water, remove it immediately and check to ensure that no
water has penetrated inside the case. Although this instrument is designed so that any water penetrating into the connector
does not permeate into the circuit inside the case, try to prevent any water entering the connector. If water does enter the
connector, the burnout display may be unavailable.
5. Battery Replacement
When the batteries approach the end of their lives, the
mark appears on the display. If this mark is displayed, replace the batteries.
To replace the batteries:
(1) Remove the battery box cover from the back of the instrument. Then replace the two AA alkaline dry batter-
ies (LR6).
(2) Refit the cover to the battery box.
NOTE
•
When inserting batteries, be careful not to mistake the polarity as this can damage the instrument.
•
When the instrument is to be stored for a long period of time, remove the batteries.
•
Do not leave dead batteries in the instrument as doing so may result in a failure or malfunction of the instrument due to a
leakage in battery liquid.
•
Both batteries should be replaced with new ones at the same time as replacing only one of the batteries may result in the
charge leaking from the new battery to the old.
6. Cleaning and Maintenance Service
• If the instrument becomes dirty, wipe the instrument with a cloth that has been dampened with water and well wrung.
• If the instrument is very dirty, use a cloth that has been dampened with a diluted neutral detergent. Do not use other detergents,
solvents, or chemicals. Doing so may cause a failure of the instrument.
• Avoid any water or other liquids from splashing onto the connector, as this may cause a failure of the instrument.
• For maintenance or repairs, contact Yokogawa Engineering Service (see the first page).
