The VPM 844 retrofit kit for testing solenoid valve
controlled distributor pumps
This test concept, too, is largely an automated process.
There are no more adjuster screws. All adjustment operations
are effected by programming the control unit. This
test, defined on the basis of strict factory specifications,
incorporates all parameters such as engine speed, pressure,
temperature, setting, waiting and measuring times.
By means of the precision voltage stabiliser (required for
VPM 844 and CRI 846) (4.1) the components are supplied
with exactly the right voltage. The processor unit (4.4) is
used for calibration and programming. Data communication
with the pump control unit is by way of specially developed
measurement and evaluation boards. Measurement of the
piston stroke Delta Phi (4.2) requires a special device.
