Dual Pumps Inverse Gradient Pumping Mode
‘X Firmware Version Only
Maintains a constant total flow rate between 2 syringe pumps. A gradient (linear function)
dispensing function is programmed into the Master pump. The secondary pump will be
automatically programmed with the inverse of the Master pump’s gradient function. The sum of
the two pump’s flow rates will be a constant. Both pumps will increase and decrease pumping
rates in tandem.
2 Modes of Operation
- Single cycle: Single ramp up or ramp down, then stop.
Set TTL setup setting RUN.0
- Continuous cycle: Ramp up, then ramp down, and repeat continuously.
Set TTL setup setting RUN.1
Requirement :
1)
2 Pumps from the NE-1000 syringe pump series with ‘X firmware upgrades.
2)
CBL-DUAL-3 dual pump communications cable.
Quick Setup:
On the Master pump only – DO NOT change default settings on the second pump.
1)
Attach the communications cable, CBL-DUAL-3, to the “To Computer” port on the back of both
pumps.
2)
Select the default Gradient Mode pumping program:
- Turn on power to the pump WHILE pressing the “Volume / Program Function” key.
- Use any up-arrow key to select Gradient Mode, displayed as:
- Press the key to select, or wait for the time out.
3)
Set the syringe diameter on the Master pump. Both pumps will use the same diameter.
(Default program assumes at least a 14.43 mm diameter).
4)
Press
on the Master pump to start the dual pump Gradient pumping program.
