Safety Information
CAUTION
Before making a measurement, check if the low battery symbol (
+
) is shown on the
display when the meter is switched on. Replace the battery if the symbol is displayed.
In the case of prolonged storage, it is preferable to remove the battery from the meter.
Avoid shaking the meter, particularly in the measurement mode.
The accuracy and function of the meter may be adversely affected by exceeding the specified
limits as well as by improper handling.
DANGER!
Use caution when working in the vicinity of powerful radiation sources.
Persons with electronic implants (e.g. cardiac pacemakers) should avoid powerful radiation
sources.
Observe the local safety regulations.
Observe the operating instructions for equipment that is used to generate or conduct
electromagnetic energy.
Be aware that secondary radiators (e.g. reflective objects such as a metallic fence) can cause a
local amplification of the field.
Be aware that the field strength in the near vicinity of radiators increases proportionally to the
inverse cube of the distance. This means that enormous field strengths can result in the
immediate vicinity of small radiation sources (e.g. leak in waveguides, inductive ovens).
Field strength measuring devices can underrate pulsed signals, particularly with radar signals in
which case significant measurement errors can arise.
All field strength measuring devices have a limited specified frequency range. Fields with spectral
components outside of this frequency range are generally incorrectly evaluated and tend to be
underrated. Before using field strength measuring devices, you should thus be certain that all field
components to be measured lie in the specified frequency range of the measuring device.
