3.5.2 Multifunctional switch
Some special functions of the instrument can be started manually using the multifunctional switch near the indication
LEDs. These functions are available in analog as well as in digital operation mode.
3.5.2.1 Normal operating functions
· In order to access these functions, press and hold the switch while the instrument is in normal operation mode (green
LED glowing).
· As long as the switch is held, the LEDs show a repeating sequence of patterns, where each pattern indicates a function.
· All indications in this sequence are continuous.
· Each pattern is shown for a number of seconds; in the table below the column Hold time indicates the time frame within
the sequence where the LEDs show the associated pattern.
· To start a function, release the switch when the LEDs show the pattern of the required function.
