5 - POWER MANAGEMENT

The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display update, it is strongly advised to select a slow refresh rate.
Please understand that NO information will be lost; the input signal will be
processed and the output signal will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example battery life-time:
battery life-time with a FAST update: about 3 years.
battery life-time with a 1 sec update: about 5 years.
Note: after a button has been pressed by the operator - the display
refresh rate will always switch to FAST for 30 seconds. When OFF is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
The unit has two power modes: operate and shelf.
After shelf has been selected, the unit can be stored for several years; it
will not process the sensor signal; the display is switched off but all
settings are stored. In this mode, power consumption is extremely low.
To wake up the unit again, press SELECT twice.
