Troubleshooting

Use the roller clamp inline with the tubing to set the flow rate as you would 

normally.
The roller clamp will speed up or slow down the rate at which fluid flows into 

the drip chamber. You’ll notice a lag between when you move the clamp and 

how the bag responds. DripAssist will echo this response time. After adjusting 

the flow rate with the clamp, allow the rate to stabilize and display on the 

DripAssist screen. 

Once you have manually set your target flow rate using the roller clamp, you may turn on the 

alarm, if desired.  

Press the         (Alarm) button to turn on

the alarm. 

In the picture to the right, the alarm has not been set.  The alarm indicator 

in the lower righthand corner of the screen displays “OFF”.

In the picture to the left, the alarm is set for 83 mL/hour.  The alarm value 

is displayed in the currently selected unit.  Note that when total volume is 

selected, the alarm icon remains, but the target value is not displayed.

DripAssist lets you see the flow rate in three different measurements: milliliters per hour (mL/hr), 

drops per minute(dp/m), and total volume since the device was powered on (vol).

 

You can toggle among these three measurement selections while the device is running by pressing 

the        (Flow Rate Measurement) button.

8. Replace the DripAssist Battery

The DripAssist uses one disposable AA battery. 

To open the battery door, push the inside edge of the battery 

compartment door firmly to the right. The door lifts up and snaps back 

into place by pushing to the left. When the battery runs low, the device 

screen shows a low battery message on the screen—BATTERY—and 

the alarm sounds. When the battery is too low to take accurate 

readings, the device stops taking readings.

The alarm sounds when the flow rate changes outside of a 

predetermined safe zone by either going too quickly or too slowly. The alarm also sounds when a 

bag is empty, if the chamber backs up with fluid, or if the roller clamp slips, causing the bag to 

enter a runaway-flow mode.

Important

: Wait until you have manually stabilized 

the flow rate before turning on the alarm.

The most common difficulty using DripAssist is correct placement on the drip chamber. If you find you are not 

getting a reading, or the numbers change significantly, check the position of the device on the drip chamber. 

Individual drops should freely fall past the orange indicator line.
When you see “--” on the screen, it means the device is not detecting any flow. This can happen for several 

reasons:

The flow rate is so fast that there is a steady stream of liquid. DripAssist cannot provide a reading from a 

solid stream. There must be individual drops for it to read correctly. If you can see drops, then so can the 

device. If you cannot see separate drops, then neither can the device.
The flow rate has not yet started, the flow rate has stopped, or the bag is empty.
The device is positioned incorrectly. Check to ensure the individual drops are passing across the orange 

indicator line on the front label.

Tip

: Some tubing sets have a needle that protrudes from the top. Ensure the needle does not 

cross the orange indicator line.
The device is too far forward on the drip chamber. Ensure the chamber fits snugly against the blue plastic 

parts.

Drip Indicator

variation in the flow that is undetectable by the human eye but readable by computer. DripAssist includes a Drip 

Indicator that flashes every time the device senses a drop. As long as the Drip Indicator is flashing with each 

drop, you can be confident the computer in the device is measuring the flow rate accurately, even if the numbers 

on the screen change. If the Drip Indicator is not flashing but you can see drops, check to ensure the DripAssist 

is correctly positioned. For more information, see the Troubleshooting section in this manual.

Alarm

The DripAssist calculates flow rates and monitors change in those rates. The alarm is optional. 

Flow Rate

You must set the flow rate manually when you use the DripAssist. The DripAssist does not control the rate of 

flow. If you can see drops in the chamber, so can the DripAssist. If you have a high flow rate so that it is a steady 

stream of fluid, the DripAssist is not able to measure the rate. The Flow Rate screen displays a RATE HI 

message when the flow rate exceeds operating conditions.

Drop Factor: 

Drop factor refers to how much fluid is in each drop. 

The size of the needle in a tubing set determines the size of the drop. 

There are four tubing set sizes: 10, 15, 20, and 60. Your country or 

clinic may use only one or two of these, but the DripAssist is designed 

to work globally, so it can accommodate all of these sizes.

Units: 

You can see the flow rate in either mL/h (milliliters per hour) or 

dp/m (drops per minute) based on how prescriptions in your clinic are 

written. The DripAssist also displays the total volume that has been 

delivered from when the device was powered on until now.

Although drops from a bag appear to fall at a constant rate, there is 

Important

: Once you turn the DripAssist off, the 

total volume measurement is reset. If this 

information is important to you, be sure to note it 

before resetting the device.
