Total Volume is the total amount of liquid dispensed in Dispense and Meter Modes. The total volume
counter will roll over after the maximum value is reached. The counter can be reset to 0 using the Clear Totalizer
screen.
Total Cycles -
Total Cycles is the total number of dispenses in Dispense and Meter modes. The total cycles counter
will go up to a maximum of 3,999,999,999 before restarting at 0. The counter can be reset to 0 using the Clear

The Direction is the direction of liquid flow through the Pump Module for Dispense and Meter modes. The
direction is either Forward or Reverse.
Dispense Volume -
The Dispense Volume is the amount of liquid dispensed in micro liters during a dispense

equal to 20% of the minimum volume for the selected pump size.
Dispense/Meter Rate -
The Dispense Rate is the rate of the pump in micro liters per second during the dispense
operation. The range is based on the pump size as shown in the Pump Minimum/Maximum Chart. The increment is
equal to 20% of the minimum rate for the selected pump size.
Load Rate -
The Load Rate is the rate the pump will operate during a load operation in micro liters per second. The
range is based on the pump size as shown in the Pump Minimum/Maximum Chart. The increment is equal to the

MCV Conserve Fluid -
MCV Conserve Fluid determines the fluid direction after a reference while moving to the MCV
starting position. The selections are either Disabled (towards the tip) or Enabled (towards the reservoir).

Setting MCV Conserve Fluid to enable conserves fluid
by pushing extra fluid back to the reservoir. This may
contaminate the reservoir or cause problems with a
pressurized reservoir.
