”
Briefly press the yellow multi-function pushbutton(s).
Now meter measures frequency on main display and Voltage on sub
display. Frequencies up to 40 KHz can be measured with this mode, but
voltage is measured accurately up to 20 KHz (See “ Influence quantities and
variations” on page 25)
To Exit this mode press yellow multi-function push button for long time.
This is acknowledged by the buzzer sounding twice.

with the KS30 measuring adapter.
On low-Voltage systems, transient over voltages of several kilovolts can occur
due to switching functions or lightning discharges. Direct connection of your
meter to such systems for voltage measurement can be dangerous. For
voltage measurements in power systems with nominal voltages upto 1000V,
use the KS30 measuring adapter. It is an adapter for
