Oil hose end meter
Operating instructions

Preparing for Operation
4.1
Resetting the partial quantity measuring mechanism - RESET
The most recently dispensed volume held in the partial quantity memory can be set to
zero using the RESET button. A reset is not possible while dispensing.
4.2
Dispensing procedure
The dispensing procedure is started or interrupted by pressing or releasing the
activation lever. If the activation lever is pressed again, the dispensing process is
continued from the point where it was interrupted, as long as the RESET button was
not pressed beforehand. The displayed value is retained until the RESET button is
pressed.
During the dispensing process all button commands are ignored!
4.3
Display of total quantity
If the TOTAL button is pressed, the display changes to the total quantity counting
mechanism. This counter can be set to zero only in programming mode.
4.4
Function monitoring
A self-test of the metering mechanism is carried out automatically every time that the
Reset button is pressed. All segments are displayed briefly and then all segments are
cleared before the display is set to zero. Impulses received during the self-test are
recorded and evaluated. All other stored values (correction factor, unit of measure) are
checked. Only when all values are in agreement is metering possible. If this is not the
case, the error message "ERR" appears on the display.
The meter permanently checks the direction of flow and the impulses received during
a dispensing procedure. If the oil flow reverses or the metering system produces
illogical signals, then "ERR" also appears on the display. If "ERR" appears repeatedly
during a dispensing process, the hose end meter must be repaired.
4.5
Programming
For programming, the locking screw (item 11) must be removed from the housing
(diagram 8-1).
For this, a seal must first be removed from the calibratable model, so that only
authorised individuals can carry out this procedure.
Keep the programming button which is located in the housing pressed for about
5 sec. and then step through the ranges one after another by repeatedly
pressing the button once.
The following ranges are displayed:
a)
cal. 0.000 L
(calibration mode and unit of measure, L or Gal.)
b)
[––or ––]
(direction of flow)
c)
CLr L
(Reset total display)
d) 1.000
(calibration
factor)
