Make sure that the removal ribbon is below the battery. 5. Place the battery into the compartment and replace access plate. Testing Battery Backup Operation 1. Place speed source selector in INTernal position. 2. With no external adapter attached, turn on POWER switch and check pump end for illumination of red LED.

Operation Stand Alone Operation 1. Insert the power jack into the pump first, then plug the 9V DC wall mount supply into an AC outlet. 2. Press in the pump POWER switch. 3. Attach inlet and outlet lines as required. Due to the low flow rates, it is usually best to attach the lines to the pump tube connector, fill the system, clear any air bubbles, pinch off the line to stop any flow and then install the pump tube into the... - Page 7 EXTspeed in input Monitor voltage Out. Stereo jack connections for EXTernal speed control The control voltage passes through the speed control potentiome- ters and can be attenuated via the knob settings. This is a useful feature when operating more than one pump from a common control line since it allows individual speed adjustment for each pump.
- Page 8 Calibration Instech’s P720 peristaltic pumps use tube sets of different sizes to cover the range of flow rates. The base model P720, with a motor that has a 900:1 gear ratio, will have flows from approximately 0.2 to 180 ml/hr (see chart below). Other models, such as the P720/66, /10K or /37K will have different ranges as shown in the spec sheet posted on the Instech website.
- Page 9 1. Attach either the inflow or the outflow tube to a container on a balance, or one whose weight is precisely known. Ensure that all the air has been removed from the lines. 2. Set the pump dials to 110 to run the motor at maximum speed (coarse speed control: 100, fine speed control: 10), and turn on the pump motor.

Next choose the tube material and inlet and outlet connectors using the table below. When ordering, give Instech a part number that specifies: inlet connector–tubing– outlet connector. For example, LL-020S-22 specifies a single channel .020” silicone tube with a male Luer lock inlet connector... - Page 11 Pumps with spur gearheads (P720/37K, P720/10K and P720) are more susceptible to this stress than are pumps with planetary gearheads (P720/66). In addition, dual 062 tube sets make contact with the sides of the pump rotor, which will cause those tube sets to wear faster than other sizes.
