3.3. Working with the unit
When the probe tip is immersed in the test solution, air bubbles can settle on its
surface, leading to errors in readings. Therefore, when measuring and calibrating
the device, it is recommended to slowly move the probe in a circular motion to
minimize the occurrence of this issue.
If too large measurement deviations occur with a properly performed calibration,
the measurement results do not reset, etc., clean the electrode with ethyl alcohol.
CONNECTING THE PROBES / CHARGING THE BATTERY
a) Each time before working with the unit, fully charge the unit's battery in
accordance with the guidelines in the technical data table. The inlet for
connecting to the power supply is located in the side housing of the device.
NOTE: If during operation of the device the backlight of the LCD display
darkens or the device displays measurements with too large deviations,
recharge the battery of the device.
b) The device has three dedicated measurement probes. The conductivity
measurement probe for EC/CF/TDS is integrated into the device. Before each
use of the device, check the correct installation of the measuring probes.
