Alarm threshold 3 (AL3 – continuous alarm and end of meas

-

uring range):

 

– When this alarm threshold is exceeded, a continuous audible 

alarm and a continuous visual alarm are triggered and 

AL3 

flashes on the display.

 

– The continuous tone is distinctly different from the operat

-

ing signal.

 

– The AL3 alarm cannot be acknowledged.

 

– There are two ways to terminate the AL3 alarm:

 

By switching to the

 Measuring VOL%

 application

 

By switching off the device

The alarm thresholds can be adjusted in the 

System menu

 

(see Section 3.3.4.2).
The setting ranges of the alarm thresholds are specified under 

Technical data (see Section 7.2).
