CALIBRATION:
All UPW testers are factory-calibrated with freshly prepared low-conductivity solutions. Infact , due to their high instability, calibration solutions in the UPW range (below 2 µS/cm) can not be supplied with the meter.
However, if your meter needs to be recalibrated, use a 1.500 µS/cm solution prepared by a qualified laboratory and keep it airtight.

BEPS AND BATTERY REPLACEMENT:
UPW UPW
UPW is supplied with BEPS (Battery Error Preventing
UPW UPW System) which avoids any erroneous reading due to low batteries level, by switching the meter off. To replace the batteries, slide off the battery com­partment cover and replace all four 1.5V batteries while paying attention to their polarity.
Batteries should only be replaced in a nonhazardous area using the battery type specified in this instruction sheet.

• Remove the screw on the back of the located below the battery compartment and slide off the whole internal part of the tester.
• Replace the built-in electrode with a new
HI73309.
• Before reinserting the internal circuit into the new plastic casing, make sure the O-rings (2) of the metal tube (3) are properly seated (see drawing).
To avoid bending the connections to the con­ductivity sensors (1), do not apply excessive force while inserting the circuit. In case of any problem, reslide and reinsert it.
