Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environ-
ment in which they are used.
Operation of these instruments in residential areas could cause unacceptable interfer-
ence to radio and TV equipment.
Any variation introduced by the user to the supplied equipment may degrade the

CALIBRATION TEST KEYS
HANNA test keys provide a quick and easy way to test the meter's
accuracy by simply plug the key to the probe socket on the meter.
If the reading differs by more than ±0.4°C (±0.8°F) from the test
key value, the unit is due for recalibration.
Choose the proper test key according to your application needs.
