TEMPERATURE CALIBRATION
(for Technical Personnel only)
INITIAL PREPARATION
Prepare a container of ice and water and
another container with hot water (at a tem-
perature of at least 50°C/122°F). Place insu-
lation material around the containers to mini-
mize temperature changes.
Use a ChecktempC or a calibrated thermom-
eter with a resolution of 0.1° as reference
thermometer.
Note: After performing the following calibra-
tion, conductivity must be recalibrated.
PROCEDURE
• Press the RANGE key to select the tem-
perature measurement mode (just tem-
perature measurement on the primary dis-
play).
• Ensure that the probe is connected to the
meter securely by aligning the pins with
the socket, pushing the plug in and tight-
ening the threaded ring. Insert the probe
