Technical issue
Solution
The display shows Err 1, Err 2, Err 3, or Err 4.
See Error Messages.
The instrument does not start.
Ensure the power cord is connected.
Ensure that the power switch is in the on position: “|”.
Check that the 2 fuses at the back of the instrument are functional (value: T3.15A).
There are air bubbles
in the diluent.
Ensure that the tubing is correctly inserted in the peristaltic pump and follows the direction
of the flow indicated on the side of the instrument.
The indicated weight
cannot remain stable.
Ensure that the instrument has been turned on for 10 minutes.
Ensure that the drip tray is properly positioned.
Ensure that the weighing cell holes are free.
Ensure that the instrument is not subjected to any vibrations.
Ensure that the instrument is horizontal.
Ensure that there is no air flow affecting the weighing.
Switch the instrument off and on to re-initialize it.
After following all of the above suggestions, repeat the calibration procedure.
The motor makes a noise
but the pump does not start.
Ensure that the tubing is correctly positioned in the pump (see Adjusting the Pump
and Inserting the Tubing).
Ensure that the tubing is not pinched.
Ensure that the rollers of the pump are not blocked.
Ensure that the pumps are set correctly (see Adjusting the Pump and Inserting the Tubing).
Stretch the tubing on both sides without opening the pump.
The pump perforates the tubing.
Ensure that the tubing has been correctly inserted and centered in the pump
(see Adjusting the Pump and Inserting the Tubing).
Ensure that the pumps are set correctly (see Adjusting the Pump and Inserting the Tubing).
The pump does not intake
the liquid.
Ensure that the pumps are correctly set (see Adjusting the Pump and Inserting the Tubing).
Ensure that the tubing is correctly inserted in the peristaltic pump and follows the direction
of the flow indicated on the side of the instrument.
Error Messages
If operation fails, the device displays an error: Err 1, Err 2, Err 3, or Err 4.
Error message
Technical issue
Solution
Err 1 (DiluCult™ 2
instrument only)
The robotic arm cannot move automatically.
Ensure that nothing is blocking the movement of the arm
and repeat the process.
Err 2
For a dilution, the weight of the sample is too
low (< 0.5 g) or too high (the total weight
after dilution should not exceed the weight
capacity of the DiluCult™ instrument).
Replace the sample and start the dilution again.
Err 3
The liquid does not flow.
Ensure that the tubing is correctly placed in the pump and
nothing is preventing the liquid from flowing in the tubing.
Press the
Go
button again.
Err 4
At the end of a calibration, one of the
2 measures (the empty weight or the
500 g calibrated weight) is wrong.
Ensure that nothing is resting on the weighing platform
that could alter the measurement.
