11.4 MICRO-SWITCH USE FOR READING/CHANGING CONTROL MODE:

11.4.1 Read control mode

For switching between different functions in use of a digital meter or controller several modes are available. More

information about the available control modes can be found at parameter “Control mode”.

Pressing the switch 2x briefly with intervals of max. 1 second in normal running/operation mode will trigger the

instrument to “show” its control mode. For indication of the control mode number the green LED will flash the

amount of tens and the red LED the amount of units in the number. The flashes are called “count-flashes” and have a

pattern of 0.5 sec. on, 0.5 sec. off. The control mode numbers can be found at parameter “control mode”
