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 instruction 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 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. Also, when using the 2-
channel model, always keep the probe-to-probe potential below 1 V.
•
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.

To select the input channel from channel A, B, or A-B:
■
Press this key.
With each press, the display changes between A, B, and A-B, allowing
you to select the input channel for measurement.
NOTE
:
• Channel switching is disabled during the RCD mode.
• By switching the channels when data is being read, you can
display the data of each channel: maximum and minimum values
and measured data saved using the Memory-in function.

resolution
To select a display resolution:
■
Press this key.
Every time this key is pressed, the display resolution alternates
between 0.1°C and 1°C (within the range of -200.0°C to 199.9°C).
If 0.1°C is selected, a resolution of 0.1°C is achieved when the display
value is 199.9°C or below; when it goes over 200°C, the resolution
changes to 1°C, and the number of display digits is switched automati-
cally. When “chA-B” is selected, the display is switched to the input
value of channel A or B, whichever is greater.
TIP
:
• The resolution setting is maintained even after the power is turned off.
The next time the power is turned on, the instrument starts up with the
setting that was set before the power was turned off.
• Factory-set resolution is 0.1°C.

display
To select relative display:
■
Press this key to select a relative display.
The display shows the difference (relative value) of a subsequent
measured value (Dx) from the reading given as a reference value (D1)
when this key was pressed.
Relative display value = Dx–D1
The reference value affects measurements on all channels (channel A,
channel B and channel A-B). Any value among MAX, MIN and MEM
can also be used as the reference value.
■
To cancel relative display, press this key again.
REL
Set
correction
value
To set the correction value for simplified correction:
The current temperature reading can be corrected to a value based on the
reference thermometer. By thus eliminating probe-specific errors, you can
take precision measurements over a frequently used temperature range.
NOTE
: When you change the measurement probe, the correction
value must be set again regardless of the thermocouple type.
■
Press and hold this key for 3 seconds.
The ADJ on the display flashes, indicating that the instrument is ready
for setting.
■
While measuring the reference temperature, correct the display value to
an optional value using the
and
keys. (The correction range is
±20°C of the measured value. Resolution of the correction value is
determined according to the resolution setting.)
TIP
: Holding down the
or
