Xylem EC510 PORTABLE CONDUCTIVITY METER KIT - Manual (Page 2)

EC500 V2.1 7/13/05 2
Introduction
Congratulations on your purchase of the ExStik ® EC500 pH/Conductivity/Total Dissolved
Solids (TDS) / Salinity meter. With the EC500’s dynamic cell-constant technology it is
possible to measure a wide range of Conductivity, TDS, and Salinity with the same
electrode. Careful use and maintenance will provide years of reliable service.
Powering the ExStik™
The ExStik ® uses four (4) CR2032 Lithium Ion Batteries (included). If the batteries are
weak, the ‘BAT’ indicator appears on the LCD. Press the ON/OFF key to turn the ExStik ®
on or off. The auto power off feature shuts the ExStik ® off automatically after 10 minutes of
inactivity to preserve battery life.
Getting Started
• Remove the cap from the bottom of the ExStik to expose the pH electrode, reference
junction and conductivity electrodes.
• Before the first use or after storage, soak the electrode in tap water or pH 4 buffer
solution for about 10 minutes.
• White KCL crystals may be present in the cap or on the electrode. This is to be
expected depending on the length of time in storage. These crystals will dissolve
while soaking the electrode or they can be rinsed away with tap water.
• For best results calibrate with pH 7 buffer solution first, then calibrate with the buffer
solution closest to the expected pH value of the solution or material to be tested.
• To preserve the pH electrode life keep the sponge in the protective cap soaked with
tap water or pH 4 buffer solution.
• For best results, calibrate for conductivity with a standard in the expected range of
the sample. For maximum accuracy calibrate from low conductivity value standards
to high value standards.
