a push on this button switches ESM-2 on and off.

➌
!
a push on this button switches the sound on and off.
The tone highth is proportional to the reading value. A
lower value generates a low frequency tone and high
reading generates a higher frequency.

If the reading is smaller than 1999 mV (in measu-
ring range of 20000 mV) or 199,9 mV (in measuring
range of 2000 mV) then
(and only then!)
, it is possible
to change the measuring range to a lower range with
push button
➎
. This is useful if a more porecixe mea-
suring is needed.
Through the high input impedance of the ESM-2 a high
measuring sensitivity is given. If no cable is insertet it
is possible, that it took a longer time until the reading in
the display is 0. It is also possible, that the reading of
the ESM-2 in the range 200,00 mV not reach zero.
This is normal and no failure!
With push butto
➍
it is always possible to change the
range to a higher state.
