CAUTION: The measurement system MUST be cali-
brated at the ambient temperature prior to making a
measurement. You must calibrate when the setup fre-
quency is changed. Calibrations and setups are not
independent; they are tied together. The instrument
can store up to six calibration/setups. When you recall
a stored setup, perform a new calibration only if the
test setup has been altered.
