Advanjet HV-2000C Jet Controller Setup and Operation

Appendix 1-3:
First Drop Compensation in PULSE Mode
In this mode, the controller produces ―n‖ drops when it receives a trigger signal,
where ―n‖ is the number of drops.
Refill Time for the first dot = T
+
Refill Time for all subsequent dots = Refill (no added first drop compensation)
If the number of drops is set to 1, the refill time will always be T
+
because
there are no subsequent dots.
Example 1: Number of drops = 1
In the timing diagram below, T* = T
+
Therefore, each drop = T
+
