FILL-FLOWMETER CALIBRATION
NOTE! The Fill-flowmeter is an independent unit. Subsequently it MUST be
calibrated individually!
However, as automatic calibration-mode is provided by your LH 4000 for the
spray-flowmeter, so it is for your FILL-meter!
The accuracy of the calibration procedure depends on the amount used for
calibration. The following example uses 1000 litres.
Please double-check the calibration of the fill-flowmeter.
Proceed thus:
1.
Select "FLOW-FIGURE" through the sub-menu.
2. Check that a figure is encoded. If not, enter e.g. 4000.
3. Press the "return"-key to return to the previous screen.
4. Enter a "FILL VOLUME" Enter approx. twice the amount you may require.
5. Press the "START FILL" key in the sub-menu.
6. Fill the tank with an exact "known" amount (through the fill flowmeter). (You
may use a weigh-bridge for optimal accuracy).
7. Select "FLOW-FIGURE" in the sub-menu. Move cursor to "TANK LITRE".
Encode the amount here.
8. Press the flashing "CALC. FLOW" key. The flow-figure will be calculated
(and entered) automatically.
