Memory-in
↓
↓
↓
To store data in internal memory (maximum of 10 data items):
■
Press the
key to hold the measured value.
■
Press the
key.
The display automatically shows the smallest memory number under
which no data has been recorded. At this point, the MEM symbol turns
on to indicate that the thermometer is in the “Memory-in” mode.
■
Use these keys to select a desired memory number under which you want
to record data. In this step, you can also check the existing data value.
TIP
: Pressing the
key while a memory number is being displayed
cancels the memory-in function (returns to measurement mode).
■
Press the
key to store the data.
TIP
: The
HOLD
and
MEM
symbols indicate that the value recorded
with the memory-in function is being held and shown. Press the
key to return to normal measurement mode.

To read maximum and minimum values and stored data
values from memory:
■
When the
key is pressed, the display changes
in the sequence shown in the figure on the right.
■
For stored data, select the memory number using the
or
key. After the memory number has been
displayed for a few seconds, the value stored in that
memory is displayed.
NOTE
:
• This data reading is disabled during thermo-
couple type selecting or correction value setting.
• If you press the
key when the REL mode
is active, each of the MIN, MAX and MEM
values is shown as a relative value based on the
reference value (D1).
• The number of display digits of maximum and minimum/stored
data depends on the current resolution setting, not the number of
display digits at the time when the data was measured.
Channel switching and display when data is being read (TX10-
03 only):
■
Data while measuring values from a single channel (either channel A or B)
Using the
;

key, display the channel used when the data was
measured. All of the maximum, minimum, and stored data values can
be displayed.
■
Data when measuring the difference between values of two channels
(channel A and B measurement)
• Pressing the
;
;
;;
;;
key to select channel A or B shows the minimum
and maximum values, as well as the memory value, measured on that
channel.
• Pressing the
;
;
;;
;;
key to select ‘chA-chB’ displays the stored values
of the difference between channels A and B as well as the maximum or
minimum difference values.
Burnout
— — — —
• When the probe is not connected to the input connector (or the sensor
opens), a burnout mark is displayed.
• For the 2-channel mode, the burnout mark is displayed when the probe is
not connected to the selected channel (channel A and B, or channel A-B)
Clear stored
data

To clear the recording memory:
■
Press the
key to display stored data.
■
Select the memory number you wish to clear.
■
Press the
key to clear the data.
To clear all the stored data in the memory at one time, press and hold
the
key for 1 to 2 seconds.
TIP
: This operation does not affect the maximum and minimum values.
3. Measurement
This instrument can connect any of the 4 types of thermocouples: Type K, J, E, or T (it is set to Type K at shipment
from the factory). Use an omega-type connector corresponding to the TC type for the probe.
(1) Load the batteries (see section 5, Battery Replacement).
(2) Press the
key to turn on the power.
When the power has been turned on, all indications on the display light up for about 2 seconds, then a measured
value appears.
(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) Select the input channel. (TX10-03 only)
Press the
;
;
;;
;;
key and select one channel from channel A, B, and A-B (see Select channel on the previous
page).
(5) Connect the probe to the input connector.
If you are using the 2-channel model (TX10-03), connect the probe(s) to the channel(s) you are using.
(6) 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.
• If the power is turned off and then on again, the instrument restarts with the same settings of the resolution
(0.1°C or 1°C), input channel (channel A, B or A-B) and thermocouple type (K, J, E or T) as before it was
turned off.
(7) Other operations
For other operations such as display hold, relative display, and maximum and minimum record/readout, see the
key operation list on the previous page.
NOTE
Key operation of this instrument is comparatively easy. However, it is necessary to make sure that the instru-
ment is not mistakenly set to a state other than that intended. Note that, under normal measurement, “HOLD,”
“RCD,” “REL,” “MAX,” “MIN,” and “MEM” are not displayed.
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. There-
fore 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 batteries
(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
• 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.

10.Regarding This Manual
• The contents of this manual are subject to change without prior notice.
• This manual is intended to describe the functions of this instrument, not to guarantee that the functions are
suited to the particular purpose of the user.
NOTE
:
• The maximum and minimum values are stored in internal memory
even after recording is cancelled. The data will be updated when
the RCD mode is enabled again.
• If you enable the RCD mode when the REL mode is active, the
reading changes to a relative value. Nevertheless, the minimum and
maximum of measured values (Dx) are stored in internal memory.
• Recorded maximum and minimum values can be referenced even
after the power is turned off and on again because they are stored
in memory until the RCD mode is enabled next time.
• Auto power-off is cancelled during the RCD mode.
