INITIAL INSPECTION AND ASSEMBLY

Carefully unpack the instrument and accessories, and inspect for shipping damages. Notify your
local dealer or YSI immediately (800-897-4151 or [e-mail]) 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 pH10 meter electrode.

2. Soak electrode in pH 4 buffer for 10 minutes before first use or after storage.

OPERATION

A. Power ON/OFF

Press “HOLD – On/Off” key for 3 seconds. The unit will turn on and enter the “Measure
Mode”. Repeat process to turn off. 10 minute automatic shutoff.

B. Set Date and Time

1. Press and Hold “CAL” key until it enters “Date/Time Set Mode”.

2. Press “HOLD” key to select date or time parameters.

3. Press “STORE”

4. Press “CAL” key for 2 seconds to return to “Measure Mode”.

key to increase value or “SCROLL” key to decrease value.

C. Select Buffer Set

1. Press and hold “SCROLL” key until unit enters “Buffer Set Select Mode”.

2. Press “SCROLL” key again to select either 7.00 (7.00/4.01/10.01) or 6.86
(6.86/4.00/9.18) buffer sets.

3. Press “STORE” key for 2 seconds to return to “Measure Mode”.

Note: This is only needed once unless changing buffer sets.

D. Calibrate pH

1. Press “CAL” key for 2 seconds and release to enter “Calibration” mode.

2. Immerse meter into either pH 7.00 or 6.86 buffer solution depending on which Buffer
Set you are using. ‘WAIT” will flash.

3. The pH10 meter will determine when the calibration reading is stable. Meter is
calibrated when “WAIT” disappears. The unit will automatically enter the next
calibration point 5 seconds later. One/first point calibration is now completed. Press
“CAL” key to exit or continue to next step for two/second point calibration.

4. Repeat Steps 2 and 3 for two/second point calibration by immersing the meter in pH

4.01/4.00 or 10.01/9.18 buffers.

5. Move to #6 for three/third point calibration or press “CAL” to exit two point calibration.

6. Repeat Steps 2 and 3 for three/third point calibration.

7. When “WAIT” disappears unit will automatically return to “Measure Mode”.

Note: For accuracy, it is recommended pH calibration is performed routinely with good buffer
solutions and a clean electrode or anytime after replacing the electrode.

E. Measure

Dip the electrode into the test solution while in the “Measure Mode”.

F. Hold Data

1. When the pH is stable, press “HOLD” key once to lock the reading on the display.
