SUGGESTIONS FOR USERS:

Before using this product, make sure that it is entirely suitable for the environ­ment in which it is used. Operation of this instrument in residential areas could
cause interference to radio and TV equipment. Any variation introduced by the
user to the supplied equipment may degrade the instrument's EMC perfor­mance. To avoid electrical shocks, do not use this instrument when voltage at
the measurement surface exceeds 24 VAC or 60 VDC. To avoid damage or
burns, do not perform any measurement in microwave ovens.

Manufacturers since 1978

The HI145 series of thermometers are available
in two versions:

HI145-00 (Celsius) and HI145-01 (Fahrenheit)
have been especially designed for penetration
of semi-solids (such as frozen food). The stain­less steel probe is 125 mm (5”) long and has a
5mm (0.2”) diameter.

HI145-20 (Celsius) and HI145-30 (Fahrenheit)
have been especially designed for temperature
measurement of hot liquids. The stainless steel
probe is 300mm (12”) long and has a 5mm
(0.2”) diameter.

OPERATION:

• Turn the HI145 on. “CAL” will appear on the
LCD, to indicate an automatic calibration check.
Subequent to a successful cali­bration check, the LCD will dis-

play “-0-”. If the calibration check
is unsuccessful, the LCD will display “ERR”,
which means the meter requires factory cali­bration. After calibration check, the meter will
automatically enter in the normal measure­ment mode.

• Introduce the HI145 probe to the sample.

• Thanks to its special shape, HI145-00
(or HI145-01) can be very easily inserted into

semi-solid samples. A minimum
immersion level of 4 cm (1½") is
recommended.

• Wait for a few seconds for the dis­play to stabilize.

• To freeze the display, press the hold button. A
blinking M appears on the right side of the
LCD to indicate that reading has been memo­rized. Press either the HOLD
or ON/OFF button to return to

normal measurement mode.

• When not in use, switch the HI145 off, or else
the meter will automatically switch off itself
after 8 minutes.

• Variations in readings or fading display can

indicate a weak battery (see below).

BATTERY REPLACEMENT:

When the HI 145 cannot be
switched on or the display fades,
unscrew the two screws to gain
access to the battery compartment.

HOLD

Change the 1.5V AAA type battery,
paying attention to its polarity.

Battery should only be replaced in
a safe area using an alkaline type.

PROTECTIVE CAP:

With the thermometer, is supplied
with a protective cap, which can also
be used to hold the thermometer
on the side of a vessel.
