Applicable only with “Rate Data Functions”.
When setting the pumping rate, if the current Phase’s function is not ‘RATE’, then is not
applicable.
While pumping, the pumping rate can only be set if the current Phase function is ‘RATE’ and the next
Program Phase’s function to be executed is not Increment (FUN INC) or Decrement (FUN DEC).
Also, while pumping, cannot be set.
The new pumping rate will only be stored in non-volatile memory if the Pumping Program is not
operating.
When the pumping rate is queried while pumping, the response will be the current pumping rate and
units. Otherwise, the response will be the rate setting and units, if applicable. With the Increment and
Decrement functions, these two responses are not the same.
RAT C [ ]
Allows the Pumping Program to continue after the pumping rate is changed. The RAT C command
will not clear a Paused Pumping state after the rate is changed when the Pumping Program is paused.
Normally, the Pumping Program would re-start from Phase 1 after the rate is changed while paused.
RAT I [ ]
Changes the pumping rate only if the pump is infusing. If the pumping direction is set to withdraw,
the rate change will be ignored.
VOLUME TO BE DISPENSED AND SET VOLUME UNITS
VOL [ | ]
Set/query volume to be dispensed:
Applicable only with “Rate Data Functions”. Can only be set when the Pumping Program is not
operating. The volume units are set according to the current syringe diameter setting. Do not send the
volume units when setting the volume.
Example: VOL 12.45
Sets the current phase “Volume to be Dispensed” to 12.45.
Set volume units:
Overrides the default volume units set when the syringe diameter is set.
Example: VOL UL
Sets all volume units to µL.
Query response:
PUMPING DIRECTION
DIR [ INF | WDR | REV | STK ]
Set/query pumping direction
INF = Infuse
WDR = Withdraw
REV = Reverse pumping direction
STK = “Sticky Direction”
Applicable with all Program Phase functions. Cannot be set when the Pumping Program is operating
and the “Volume to be Dispensed” is non-zero.
The pumping direction cannot be changed if an alarm condition exists.
Query response: { INF | WDR | STK }
When set to “Sticky Direction”, query will respond with the current pumping direction (INF or WDR)
while pumping.
