(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.
