TEMPERATURE CALIBRATION
(for Technical Personnel only)
You can perform the temperature calibration
as follows.
INITIAL PREPARATION
• Prepare a vessel containing
ice and water and another
one containing hot water (at
a temperature of 50°C/122°F). Place insu-
lation material around the container to mini-
mize temperature changes.
• Use a ChecktempC or a calibrated ther-
mometer with a resolution of 0.1°C as a
reference thermometer.
PROCEDURE
• Turn the meter ON and
press the RANGE key twice
to get just the temperature
reading on the display.
• Immerse the temperature probe
in the container of ice and wa-
ter. Place the probe as close
as possible to the reference ther-
mometer.
• Press the CAL key. The secondary display
(lower) LCD will blink "0" for approximately
30 seconds.
