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 automatically.
When “chA-B” is selected, the display is switched to the input value
of channel A or B, whichever is greater.
• The resolution setting is maintained even after the power is
turned off.

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 the REL key again.
To turn simplied correction on and off

flashes.
ADJ
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.
When you change the measurement probe, the correction
value must be set again regardless of the thermocouple type.
■ Press and hold the REL key about 3 seconds.
The ADJ on the display flashes, indicating that the instrument is
ready for setting.
■ Carry out the correction.
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 [ ▼] key increases the speed with
which the display value changes. (a value continues to change)

recording
• 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.
Recording of the maximum and minimum values:
Detection and recording of the max./min. values starts
when the RECORD key is pressed and continues until this key
is pressed again or the power is turned off.
Enable the RCD mode after selecting the channel.
■ To start recording, press the RECORD key.
■ To stop the recording, press the RECORD key again.
Measurement on channel A-B is done as described below.

• 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.
• This data reading is disabled during thermocouple type selecting or
correction value setting.
• If you press the READ 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.
■ Select the memory number.
For stored data, select the memory
number using the [ ▲ ] or [ ▼ ] key.
After the memory number has been
displayed for a few seconds,

8. 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.
[ Procedure ]
(1) Load the batteries (see section "9. 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 the measured value appears.
Burnout indication: - - - -
When the probe is not connected to the input connector,
a burnout mark is displayed.
(3) Check the thermocouple type.
If you wish to change the current setting, see "To select a thermocouple type" of
section "6.2 Functional Description."
(4) Select the input channel. (TX1003 only)
Press the key and select one channel from channel A, B, and A-B.
(see "To select the input channel.")
(5) Connect the probe to the input connector.
If you are using the 2-channel model (TX1003), connect the probe(s) to the channel(s)
you are using. (The measured value appears.)
(6) When you have nished 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.
For other operations such as display hold, relative display, and maximum and minimum
record/readout, see section "7.2 Functional Description."
NOTE
Key operation of this instrument is comparatively easy.
However, it is necessary to make sure that the instrument 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.
9. Battery Replacement
CAUTION
• 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.
Attention
• Lors de l'insertion des piles, faire en sorte de ne pas confondre de polarité, car cela
risquerait d'endommager l'instrument.
• Si l'instrument doit être stocké pendant une longue période, retirer les piles.
• Ne pas laisser de vieilles piles usagées dans l'instrument, car cela risquerait sinon
d'entraîner une défaillance ou un dysfonctionnement de l'instrument dû(e) à une fuite du
liquide des piles.
• Les deux piles doivent être remplacées par des nouvelles en même moment, car le fait de
n'en remplacer qu'une seule risque d'entraîner un transfert de charge de la nouvelle pile
vers l'ancienne.
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 (rear) of the instrument.
Then replace the two AA alkaline dry batteries (LR6).
(2) Ret the cover to the battery box.
