Setup and Operation 3.12 Adjusting the intensity of the backlight General description of multifunctional counter 4 General description of multifunctional counter For counters that come with a backlight you have the possibility to adjust the intensity of their backlight. The following description is applicable for all standard settings. Special de scriptions can be found in the appropriate chapters of this manual. Factory setting (Defaults) To get into the menu of the adjustment, you have to press SHIFT for more than 5 seconds. The display then shows: Sets all the function codes to the factory settings, i.e. all codes designated with *. Prescaler (pulse metering factor):
By pressing the UP or DOWN key the display gets brighter or darker. The “Prescaler” is a multiplier. Each input pulse is multiplied by the adjusted factor. The display shows integers only. After a reset the counter is completely reset to 0; this also includes the non-visible value of If the E-button is pressed within 15 s, you go back to the normal counter dis play and the adjusted setting is saved. If the E-button is not pressed within 15 seconds, you will go back automatically to the normal counter menu without saving any made changes. At a prescaler of >1 not all the values are selectable. If invalid Preset values are selected, the counter will round them up to the next possible value.
Go to the adjustment menu Adjustment of the in tensity Save and going back to display mode Example: PSC 5 cannot select (reach) Preset value 7. In this case, the counter automatically changes the Preset value to 10). If the Prescaler is changed, this may also affect the Preset values, which may have to be changed accordingly. pressing > 5 s press Pressing within 15 s or Adjusting range 0,0001 to 99,9999 The Prescaler is used, for example, to convert counter pulses into meaningful units, to adapt the units of measurements (e.g. cm-pulses to inch-pulses), or to compensate for worn out measuring wheels. Formula: PSC = Desired/nominal display / number of pulses Example:
Flowmeter 173 pulses per 100 liters; display in liters PSC = 100 / 173 = 0,5780 Example: 1 pulse per cm; display in inch PSC = 1 / 2,54 = 0,3937 32 33
