Manual Calibration of New Liquids
According to the specific correlation of dosing energy and generated droplet
volume, a liquid class can be defined as a polynomial equation. By
modification of the individual parameters, the liquid class can be adjusted
manually. Adjust the parameter values for “M”, “N”, “Min” and “Max” (see
Figure 27. Liquid Class Parameters and Values
•
M (Slopes)
: Specifies the generated droplet volume in nanoliter (nL) upon
application of 1 Laske (1 La) during the pressure pulse.
•
N (Offset)
: Specifies the intersection of the graph with the Y-axis. Default
0 nL.
•
Min (Minimum dosing energy)
: Specifies the lowest pressure to be
applied for the respective liquid class. Default 50 La.
•
Max (Maximum dosing energy)
: Specifies the highest pressure to be
applied for the respective liquid class. Default 300 La.

NOTE:
“Laske” (La) is a specific unit of pressure, expressing mbar*ms. It
describes the relationship of pressure and mechanical valve
opening time.
NOTE:
Increasing the maximum dosing energy might be required for liquids
more viscous than water. However, 300 La is recommended and
sufficient for most fluids. We recommend increasing in 50 La
increments, if necessary.
