INITIAL INSPECTION AND ASSEMBLY
Carefully unpack the instrument and accessories, and inspect for shipping damages. Notify
your local dealer or YSI immediately (+1 937-767-7241 or environmental@ysi.com) of any
damages or missing parts. Save packing materials until satisfactory operation is confirmed.
BEFORE USING
A. Insert the Batteries
1. Remove the battery cap at the top of the unit.
2. Insert the set of batteries (included) ensuring correct polarities.
3. Securely replace battery cap.
B. Soak the Electrode
1. Remove the electrode cap covering the EC30A meter electrode.
2. Soak electrode in distilled water for 10 minutes before first use or after storage
.
OPERATION
A. Power ON/OFF
Press the “On/Off” key. The unit will turn on and enter the “Measure Mode”. Press the key
again to turn off. The instrument has a 10 minute automatic shutoff if there is no key activity
unless it is submersed in solution.
B. Calibrate
1. Press “CAL” key to enter “Calibration” mode.
2. Immerse meter into 1000 µS conductivity solution.
3. The “CAL” icon will appear when the main display shows “1000”. Single Point calibration is
now complete. The “MEAS” icon will appear and the meter is ready to measure 0-2000 µS.
Rinse electrode.
4. Repeat Steps 2 and 3 for two/second point calibration by immersing the meter in 10,000 µS
(10 mS) conductivity solution and pressing the “Cal” key. Once completed, Two Point
calibration is successful and the meter is ready to measure 0-20 mS.
Note: For accuracy, it is recommended conductivity calibration is performed routinely with good
solutions and a clean electrode or anytime after replacing the electrode.
C. Measure
Dip the electrode into the test solution while in the “Measure Mode”. Give the meter a shake
while submersed to remove any air bubbles that may have occurred during submersion.
D. Hold Data
1. When the conductivity is stable, press “HOLD” key once to lock the reading on the display.
2. Press “HOLD” key again to unlock reading and the unit will return to “Measure Mode”.
The unit is now ready for another measurement.
ONGOING MAINTENANCE
A. Electrode Storage
1. Electrodes attached to the instrument should be kept in a clean, dry environment. The
electrodes need to be kept clean.
B. Battery Disposal
This instrument is powered by alkaline batteries, which the user must remove and dispose of
when the batteries no longer power the instrument. Disposal requirements vary by country and
region, and users are expected to understand and follow the battery disposal requirements for
their specific locale.
