Cautions
To use the thermometer properly, follow the instructions below.
Do not use the device as a clinical thermometer.
Hold the device in your hand while in use.
Leaving the device in a hot pot or the
like may result in a deformation or malfunction.
Do not use the sensor sheath as a handgrip,
or the device may
fall and get broken.
Sensor sheaths are made only to
protect sensor needles when not in
use.
Do not drop or give a shock to the device, as it is a sensitive instrument.
Do not use the device under direct sunlight or aside a heat source, or it may worsen
the measurement accuracy and result in a deformation or malfunction.
Do not use the device in an environment with electrical noise, or the display may
become unstable or the measurement error may increase. Some induction
cooktops may affect the measurement, although the device is designed to resist
them.
Do not measure temperature out of the measurable range, or it may result in
malfunctions.
To eliminate the effect from ambient temperature and improve accuracy, insert the
needle in a target for 20 times as long as the diameter of the sensor needle, thus
30 mm.
Do not remain the needle inserted in a target for more than a minute if it is hot, or
the heat may reach the main body and lead to a measurement error or deformation.
For your reference, PC-9230 and PC-9235 needs only 10 seconds to finish
measurement when the needle in a room temperature is inserted in boiling water.
Stay distant from the target and be sure not to burn yourself when it is hot.
After measuring high temperature, wait until the needle cools down before
installing the sensor sheath.
For PC-9230, round holes on the sensor sheath faces up when it covers the needle.
For PC-9235, a projection on the sensor sheath faces up when it does the same.
Do not leave the device in a place like an automobile on a fine summer day, or the
extreme heat may damage the thermometer.
Remove batteries if the device is not used for a long period of time. Otherwise, the
batteries may leak resulting in malfunctions.
Wet hands or water splashes do not affect the function of the device. However,
underwater use is forbidden.
Do not disassemble or customize the device, or it may cause a fatal malfunction.
PC-9230 and PC-9235 can be fully rinsed with tap water unless they are kept
submerged in water. After washing, wipe out with a dry cloth thoroughly.
Do not wash or wipe the device with alcohol, thinner, or other organic solvents. Do
not throw it in a dryer, either.
For repair or calibration, contact us or a retailer from which you have purchased.
