6-4. Connecting the Temperature Probe
(1) While the unit is turned off, insert the probe connector into the unit by aligning the convex part of the probe
connector with the concave part of the connector on the unit.
(2) Turn the nut of the probe connector clockwise to secure the connector.
(3) To disconnect the probe, turn the nut counterclockwise to remove it. Then pull the probe connector straight
out.
Important: To protect the temperature probe, make sure
that the unit is turned off before installing or
removing the probe.
Cautions
Never forcefully rotate or pull the connector to avoid the causes of trouble.
The inside of the probe connector is not waterproof. When removing or connecting the probe from the
main body, don’t do with wet hands and in places subject to water.
6-5. How to measure temperature
(1) Connect the probe to the main unit and turn the power ON.
After all characters are lit in the display section, serial number of the unit and the calibration date are
indicated. Then measured value is indicated (temperature measurement mode).
NB. * If the probe is disconnected when power is turned on, error message "Er2" will be displayed.
* Factory default setting of the calibration date is "- - - -" When you require us to calibrate or repair
the unit, the calibration date will be indicated after the calibration or repair is done at our factory.
(2) Insert the sensing stem into the object to be measured.
To measure temperature precisely, insert the sensing stem to the depth of about 15 times as deep as the
diameter of stem (ex. deeper than 45 mm in the 3mm dia. probe) by reason that the sensor will be less
affected by the open air around the sensing stem.
(3) After the measurement, press the POWER key again to turn the power will OFF.
Cautions
- Be careful not to burn yourself when measuring high temperature.
- If you need to measure both objects having a large difference (high and low temperatures), do not continuously
carry on both measurements. Return the temperature of the temperature sensor (probe) to the normal
temperature once and then start next measurement. Otherwise, the temperature sensor deterioration will be
accelerated
-
A sudden change of the ambient temperature of the unit may adversely affect the measurement accuracy.
For the accurate measurement, start the measurement after leaving the unit in the ambient temperature.
