Calibration Factor (CAL)
The Calibration factor (CAL) provides a means to improve the accuracy of the results display by
calibrating against the output of a known frequency generator. The field strength value measured
is multiplied by the value of CAL that has been entered and the resulting value is displayed. The
CAL setting range is from 0.20 to 5.00. The measurement accuracy will be sufficient for most
applications even if the frequency response of the sensor calibration factor is ignored and the CAL
is set to 1.00 in at all points.
Setting the calibration factor (CAL)
Hold-on
Power off

When the meter is normally turned on, the calibration factor set value will display for 2
seconds.
1. Press
key to turn off the meter.
2. Press and hold on the
XYZ/CAL key, then press
key to turn on the meter to enter
the calibration factor setting mode, the “ CAL SEt ” marks is displayed.
3. Press
S or T key to increase or decrease the value.
4. Press the
SET key to store the new setting value and exit.
