set the desired volume by aligning the pointer on the volume adjustment knob with
the scale on the main housing.
Tighten the screw after aligning with the scale.

User calibration procedure

Dispenser has been laboratory calibrated to its nominal volume. However, due to changes in
environmental conditions and the viscosity of the media which you dispense, a re-calibration might be
required. You can either re-calibrate at regular intervals such as once a week or whenever you notice
that the dispensed volume is different from the volume displayed by the unit.
To fully re-calibrate your Dispenser follow the following steps:
1. Set the Dispenser to the nominal volume or any other volume which is the most common volume you
dispense.
2. Follow the common rules for calibration used in statistical quality control (ISO 8655/2). Set the volume
and Dispense five full volumes of distilled water at 20°C on Electronic Balance to establish the actual
mean volume of liquid dispensed. If the gravitational average result varies from the volume displayed,
you should re-calibrate the Dispenser.
3.
For re-calibration pull the cap outwards to expose the Calibration Nut.
4. Using the calibration tool, turn the calibration nut clockwise to reduce the volume and anticlockwise
to increase the volume. Repeat this procedure a few times till the desired volume is achieved.

Maintenance / Cleaning

Note: All maintenance should be carried out wearing suitable eye protection and protective clothing. If
in doubt, consult your safety officer.
1.
Make sure that the Dispenser is completely empty.
2. Place the instrument into an empty sink together with its reservoir.
