EC DECLARATION OF CONFORMITY & GENERAL GUIDELINES 1
EC Declaration of Conformity
This is to certify that the 343 conforms to the protection
requirements of the council directive 89/336/EEC, in the approxi-
mation of laws of the member states relating to Electromagnetic
compatibility by application of the following standards:
EN 50081-1 1992 Emissions Standard
EN 50082-1 1992 Immunity Standard
To ensure conformity with these standards, this instrument
must be operated in accordance with the instructions and speci-
fications given in this manual.
General Guidelines
ALWAYS
• Test the 343 before using it to make sure it is operating proper-
ly.
• Inspect temperature probes before using to make sure there are
no breaks or shorts.
• Double check all connections before testing.
NEVER
• Insert the probe into an electrically charged medium.
• Touch the probe tip and shaft after it has been inserted in hot
material.
MEASUREMENT TECHNIQUES 3
WARNING: Please follow manufacturers test procedures whenever
possible. Make sure probe tip and shaft are thoroughly cleaned
before inserting it into any food product.
1. Controls and Functions:
Push Buttons
Turns the 343 on and off.
°C/°F Selects Centigrade of Fahrenheit
Min/Max Selects Min or Max reading measured
T1/T2/∆T Selects probe and differential mode
HOLD Freezes the reading on the LCD
2. Step by Step Procedures
a. Connect a temperature probe or probes to the 343.
b. Turn the 343 on.
c. Insert the tip of the probe into the substance being mea-
sured.
d. Read the temperature on the LCD, allowing approximately
30 seconds for the reading to stabilize. Use the push but-
tons to switch between probes and access other funtions
as described above.
FIELD CALIBRATION 4
The 343 has the ability to be field calibrated. Accuracy of +/-1°F
within the 30°F to 120°F range can be achieved by performing an ice
bath calibration.
The temperature of an ice bath is approximately 32°F(0°C). Fill a
plastic or metal container with crushed ice and add clean water to a
depth of at least 4 inches. Stir the ice and water for 2 to 3 minutes
prior to performing calibration to ensure the water is completely
chilled. Make certain there is plenty of ice in the mixture and
always use clean water. Distilled water works well.
1. Step by Step Procedures
a. Connect both temperature probes to the 343.
b. Press and hold down the MIN/MAX and HOLD buttons and
turn the 343 on. CALF will be displayed and the 343 will
enter calibration mode and begin cycling between T1 and
T2.
c. Insert the probes into the ice bath and allow the readings to
stabilize.
d. Once the reading on both inputs has stabilized, press the
HOLD button. SAVE will be displayed and calibration is
complete.

MAINTENANCE
1. Battery Replacement: The 343 will display battery symbol when the
internal 9 Volt battery needs replacement. Replace battery as follows:
a. Disconnect and remove all temperature probes from 343.
b. Loosen the 4 screws from the back of the 343.
c. Remove the back cover.
d. Remove old battery and replace it with new battery.
f. Reassemble instrument in reverse order from above.
2. Cleaning your 343
Use a mild detergent and slightly damp cloth to clean the surfaces of
343.
