4. SPECIAL FUNCTIONS
4.1 SWITCHING ON PERMANENTLY
After 10 minutes of operation without pressing a button or turning the rotary switch or reading the digital
output, a battery economy system puts the instrument to sleep. This auto Off is preceded by a beep and
ashing of the digital display for one minute.
If you operate the instrument whilst it is ashing, the instrument will continue its active operation for a
further period of 10 minutes in the selected functions and without taking into account the button pressed
to wake it up. If you turn the switch the instrument will continue to operate for a further 10 minutes.
To avoid your Fieldmeter setting to sleep mode every 10 minutes, you can cancel the Auto Off function.
To do this, press HOLD simultaneously when switching On with the rotary switch. The symbol is
displayed indicating that the eldmeter is in permanent operation. This cancellation of the Auto Off function
is cancelled when the instrument is next switched Off (switch to the OFF position).
Note: Auto Off is automatically cancelled on RECORD mode and in certain cases, on the SCAN function.
4.2 DEACTIVATING THE «BEEP»
A buzzer, which is a piezzo-electric chip, is used to indicate that buttons are being pressed and different
functions used. The table below denes the frequencies and the lengths of the beeps in all the functions
of the instrument.
