Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environment in which they are used. Operation of
these instruments in residential areas could cause unacceptable interferences 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 shock, do
not use these instruments when voltages at the measurement surface exceed 24 Vac or 60 Vdc. To avoid damages or burns, do
not perform any measurement in microwave ovens.

Checktemp 4 are high accuracy thermometers, easy to use, offering quick and
precise measurements.
Checktemp 4 is the ideal solution for food applications. The sharp stainless
steel probe is specially designed for penetration of cooked as well as on semi-
frozen food. In addition, the probe nestles in the casing to make the
thermometers truly portable.
Checktemp 4 is equipped with the Cal-Check feature. Every time the meter is
turned on, it performs a self test of its calibration status and provides a visual
confirmation.
Two models are available:
• HI 151-00 measures temperature in °C
• HI 151-01 measures temperature in °F.
The meters are calibrated using four temperature points.
TAKING MEASUREMENTS
• Turn the meter on by simply opening the probe.
• Introduce the probe in the sample. For ideal measurement an immersion level
of 4 cm (11/2’’) is recommended. Wait for a few seconds for the reading to
stabilize and for the temperature value be displayed on the LCD.
• After 5 minutes, the meter switches itself off. To restart, close and open the
probe again.
• Turn the meter off by closing the probe and returning it to its original position.
Note:Clean the probe after use and before storing it.
CALIBRATION SELF CHECK
Every time the meter is switched on, it checks its calibration status.
If the LCD displays “CAL” and then -0- the meter is calibrated and in a few
seconds it will be ready for normal operating mode.
If the meter is not calibrated or the battery level is too low, the “Err” indication
appears on the LCD.
First replace the battery as described below; if the “Err” warning message is still
displayed, contact your dealer or your nearest Hanna Service Center for recalibra-
tion.
BATTERY REPLACEMENT
“Err” warning message, variations in readings or fading display can indicate a
low battery level. Remove the cover of the battery compartment on the back side
and replace the 1.5V AA battery while paying attention to its polarity.
