measuring is to be carried out.
(3) Data HOLD function
While the sensor measures the temperature, temperature data currently indicated on the display
is held by pressing the key
While the thermo-hygro sensor (THD-700-P) is measuring temperature and humidity, thermo-hygro
data currently indicated is held indicating “D.HOLD”on the display by pressing the key.
(Temperature is indicated on the Data display and humidity is indicated on the PV display.)
Press the key again to cancel the Data HOLD. When Data HOLD is cancelled the indication
“D.HOLD”is put out and the mode reverts to the normal measuring mode.
(4) Peak HOLD function
While the sensor is measuring temperature, “P.HOLD”is indicated on the display and the
maximum value of the temperature data currently indicated is held by pressing the MODE
key for 1 second. While thermo-hygro sensor (THD-700-P) is measuring temperature and humidity,
“P.HOLD”is indicated on the display and the maximum value of humidity data currently indicated

5.2 Immersion type thermocouple measuring mode
(1) Turn the power on by pressing the POWER key.
(2) If it is in the measuring mode, change the mode to the immersion type thermocouple measuring
mode referring to 4.3 Setup section. “EI”is indicated at the right bottom of the display
if it is in the immersion type thermocouple measuring mode.
However, even if it is changed to immersion type thermocouple measuring mode, when 0 is set
in the time setting, the mode is still Peak HOLD measuring mode and “P.HOLD EI”is indicated
at the right bottom of the display.
(3) Temperature measuring starts.
•When “EI”is indicated at the right bottom of the display
When temperature exceeds the value which was preset by timer start temperature setting,
the timer starts. After it starts, when the time that was preset has passed, the temperature data
is held and starts blinking. (When Auto-Power-Off is set, at this moment time for Auto-Power-Off
starts counting. Unless DFT is operated within a preset time, power is automatically turned off.)
Press the key to cancel the blinking indication. A blinking indication is cancelled and the
current temperature is indicated.
However, even if blinking is cancelled, when the indicated temperature is higher than the value
that was set in the timer start temperature setting, EI function does not work.
To start EI function again, be sure to let the indicated temperature be -5(10 ) or lower.
•When “P.HOLD EI”is indicated at the right bottom of the display.
This is Peak HOLD (P.HOLD) measuring mode. (When Auto-Power-Off is set, power is
automatically turned off unless DFT is operated within a preset time.)
To cancel Peak HOLD (P. HOLD), press the key.
The held data is cleared after pressing the key and the measured value is indicated when
the key is pressed.

•Automatic cold junction temperature compensation (Only thermocouple input)
Detects the temperature at thermocouple and connecting terminal of this instrument and constantly
keeps the reference junction status at 0 or 32
•Auto-Power-Off
In order to keep batteries from consuming the power of DFT, it is turned off automatically
unless operation is carried out within the preset time. However, when the measuring is carried out
in immersion type thermocouple measuring mode (when timer is active), power to the DFT is
automatically turned off unless DFT is operated within the preset time after timer action is over.

timer start temperature, the timer starts countdown, and the data is indicated on the PV display at the
same time with the Time-up and the indication blinks.
(HOLD value indicates the value at the Time-up regardless of sensor burnout.)
However, after blinking is cancelled or power is turned on, if the indicated temperature is higher
than the value preset in timer start temperature setting, EI function does not work.

Shinko Technos is not liable for any damages after using sensors.
•DFT-700 temperature sensor is used for temperature measurement.
Never use it except for the purpose of temperature measurement.
•Please adjust the DFT-700-M input to the sensor type.
•When sensor type does not match the input type, reliable measured value cannot be obtained
•Sensor type is written at the cord terminal e.g. “K, Pt100”along with high limit measuring
temperature.
•Reliable measured value cannot be obtained when temperature is measured where electricity
is running.
•Never use sensor for human body. (e.g. Taking temperature, etc.)
•Do not touch the sensor measuring part (metal section, etc) protection tube after
measuring the temperature of hot or cold objects, as this may cause burning or frostbite.
•Be sure to turn the power OFF of DFT-700-M, when DFT-700 thermo-hygro sensor (hereinafter
THD-700-P) is attached or detached from DFT-700-M.
•Do not attach or detach THD-700-P in wet place or with wet hands because it may cause
electric shock.
Warning
•The maximum temperature written in the table is the limit temperature of the measuring part.
Use such as grip, cord, etc in an ambient temperature (0 to 60 ) except for the measuring part.
•When it is used in a high temperature atmosphere, which may cause breakdown or ignition.
•When measuring under -50 atmosphere, sensor elasticity deteriorates and sensor becomes
fragile.
•Do not use this in a place with electric noise such as high magnet field and high frequency,
or DFT-700-M and sensor may breakdown or be damaged.
•Do not use this in a place with corrosive atmosphere such as acid, alkali, etc, because
that may hasten the sensor degradation and be responsible for breakdowns.
•Do not cool down the measuring part quickly such as soaking in water after measuring.
That may cause breakdown.
•Do not drop sensor and THD-700-P, strike them with hard objects, press hard on them,
as this may lead to the breakdown or malfunction.
•Use THD-700-P within the proper conditions (temperature, humidity and atmosphere, etc.)
