Example 2: Measuring a 30 MHz intercom emission frequency
Set the FUNCTION to the 2-step position and select the gate time (adjust manually from 100 ms to 10 s).
The LED display reads:
Example 3: Measuring a self-oscillating frequency (e.g. from a telephone, intercom etc.)
Set the FUNCTION key to the 2-step position. Connect one end of a test cable with 5 pF capacitance to
the red clamp; use the other end to measure the frequency by touching the contact point.
6. Warnings

When measuring a high-voltage or strong RF signal, make sure that the cables are in series and have
a large capacitance to avoid damage.

Press the RESET button once to reset the device or turn off the device in case the device is not
working appropriately.

When there is no input signal, the display may not necessarily read "0". This is absolutely normal and
does not affect the measurements or the accuracy.

Do not expose the device to extreme temperatures, humidity, dirt, dust, etc. Do not open the device
to avoid lethal electroshocks.

A strong interference will reduce the sensitivity when measuring.
