A gravimetric testing based recalibration of the burette is recommended
every 6-12 months depending on the following factors:
Frequency of use Changes in environmental conditions
The viscosity of the media
For Microlit E-Burette, gravimetric volume testing according to DIN EN ISO
8655-3 should be performed as follows:
Calculation of accuracy
(A %) and coefficient of
variation (CV %) are
calculated according to
the formulas for statistical
control.
Click the settings icon on the bottom right of the control panel
home screen.
From the settings menu, choose calibration.
Fill the nominal volume of double-distilled deionized water by clicking
the FILL button on the calibration screen of the operating panel.
Dispense the filled liquid by clicking on the DISPENSE button on the
calibration screen of the control panel.
Measure the dispensed liquid on a balance and enter the value in mg
using the provided electronic keyboard. Click the tick mark to proceed.
CAL label will start appearing on the top of the screen.
Repeat the procedure until the nominal volume is achieved on the
electronic balance.
