frequency of a single signal is known. The field

strength value measured internally is multiplied by

the value of CAL that has been entered and the

resulting value is displayed. The CAL factor is

often used as a means of entering the sensitivity

of the field sensor in terms of its frequency

response in order to improve measurement

accuracy.

11 Making measurements

Important :

The following effect will be noted with all field

strength meters:

If the sensor is moved quickly, excessive field

strength values could be displayed. This effect is

caused by electrostatic charges.

Hold the meter steady during the measurement.

12 Short-term measurements

Application :

Use either the "instantaneous" or the "Max.

instantaneous" mode, if the characteristics and
