Instruction
SONOMETER™ 1100
The push-button is used to switch through the various displays.
The button can be pressed for a short or long time. A short press
of the button
(< 3 seconds) switches to the next display within a loop and a long
press (> 3 seconds) switches to the next display loop. The “Energy”
window (sequence 1.1) in the main loop is the basic display. The
meter automatically switches off the display to save power if the
button is not pressed for
approx. 4 minutes (except in the event of fault) and returns to the
basic display when the button is pressed again.
10.0 Simple operation
The error code is displayed in the main loop if an error occurs. All the
other windows can still be selected by pressing the button. The error
code display appears again automatically if the button is not pressed
for approx. 4 minutes.
The error display disappears automatically as soon as the cause of the
error has been cleared. All errors present longer than 6 minutes are
saved in the error log.
