1. Loosen plug ”P” and attach the pressure gauge.
2. Lift nozzle 1 and start a “filling” and stop directly again. This will activate the Additive system.
3. Read the pressure and adjust to 6 bar by ”p1”.
4. When the pressure is set to 6 bar, put back the nozzle and remove the pressure gauge and
remount the plug ”P”.
2.8.3 Calibration of additive system
To calibrate a node, do the following:1.
Use a graduated cylinder with a volume > 100 ml and 1 ml resolution. Place the cylinder
at the node, so that the fluid goes into it.
a.
In operation O757.003, enter the node number to be calibrated. For example ”#”, ”1”,
”ENTER” to calibrate node #1.
b.
The display shows ”CALibr” and fluid is delivered until the predetermined calibration
volume is reached (F067.05n = 1000 = 100 ml). The actual volume is displayed in the
volume display (may be slightly higher than 1000)
Check that the volume delivered is 100 ml ±2 ml. Fill in the protocol.c.
Press ”CLEAR” to leave the calibration menu.2.
