Hanna Instruments HI 145-00 - Manual (Page 2)

The HI 145 thermometer is the ideal solution for
temperature monitoring of semi-solids, such as fro-
zen foods, as well as applications, such as in food
preparation and during cooking.
The HI 145 series is equipped with the exclusive
Cal-Check
® feature. When teh instrument is turned
on, it performs a self check of its calibration status
and displyas it on the LCD.
HI 145-00 (°C) and HI 145-01 (°F) are equipped with
a 125 mm (5”) long AISI 316 stainless steel probe.
It has a conic sharp tip which provides fast re-
sponse and improved accuracy over the entire range.
HI 145-20 (°C) and HI 145-30 (°F) are supplied with
a 300 mm (12”) long stainless steel probe and are
ideal for monitoring hot liquids in cooking applica-
tions, such as deep frying and soup preparation.
OPERATION
• Turn the HI 145 on. The “CAL” message on the
LCD indicates that the instrument is performing
an automatic calibration check. If the test is suc-
cessful, the LCD will display “-0-”. If the calibra-
tion check fails and the meter requires re-calibra-
tion, the LCD will display “ERR”.
After performing the calibration check, the instru-
ment will automatically enter the normal mea-
surement mode.
• Insert the probe into the sample to be measured.
Thanks to the special probe shape, the insertion
even into semi-solid samples is very easy.
• 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 button to return to the normal mode.
• After use, switch the instrument off, or the meter
automatically turns off after 8 minutes of non-use.
• Variations in readings or fading display can
indicate a low battery level.
FACTORY CALIBRATION
If the meter needs re-calibration, contact your deal-
er or the nearest Hanna service center.
It is recommended to recalibrate the thermometer
once a year.
BATTERY REPLACEMENT
When the HI 145 cannot be switched
on or the display fades, unscrew the
two screws to access the battery com-
partment and replace the 1.5V AAA
battery, while paying attention to its
polarity.
Battery should only be replaced in a
safe area using a 1.5V AAA alkaline
battery.
PROTECTIVE CAP
The thermometer is supplied with a
protective cap, which can also be
used to hold the thermometer on the
side of a vessel.
