Electrode Maintenance
• Rinse the electrode with tap water or electrode storage solution after each measurement.
• Periodic soaks in warm pH 4.01 buffer will help remove contaminants.
• If possible, keep a small piece of paper or sponge in the electrode cap – moistened with clean water or electrode storage solution (NOT deionized water) and close the cap over the electrode.
When you need a new electrode, see “Electrode Replacement” on insert in back of box.
Changing Batteries
2. Remove old batteries; replace with fresh ones. Note polarity (shown in Diagram 1).

Before You Begin
Remove electrode cap. To condition electrode,
immerse electrode in electrode solution, buffer
or tap water for at least 30 minutes. DO NOT use
deionized water
Calibration
Calibration should be done regularly, typically
everyday that the tester is used. You can calibrate at up to three points (pH 4.01, 7.00 and 10.01
or 4.01, 6.86 and 9.18).
1. Press ON/OFF button to switch unit on.
2. Dip electrode about 2 to 3 cm into pH buffer
solution.
3. Press CAL button to enter Calibrate (CAL) mode. ‘CAL’ flashes on the display. Then, a
pH value close to the pH buffer value will
flash repeatedly.
To abort calibration, press CAL again to
resume measuring mode.
4. After about 2 minutes when the reading has stabilized, press the
HOLD/CON button to confirm
calibration. The display will show ‘CO’
and then switch to the buffer value
reading.
5. Repeat with other buffers if necessary. Rinse electrode in tap water before dipping into next buffer.
Insufficient sampling time. If the tester does not have a long
enough exposure to the buffer, a stable calibration point will not be reached.
Wait for about 2 minutes when the
reading has stabilized, press the
HOLD/CON.
Failure to re-hydrate the electrode. A dry electrode will give
fluctuating readings while it
re-hydrates in a buffer, causing error.
Buffer Set Selection
To choose USA (4.01, 7.00, 10.01) or NIST (4.01,
6.86, 9.18) buffers.
1. With tester off, hold HOLD/CON key while pressing and releasing ON/OFF key.
2. The display will show “bUF” flashing.
3. Press HOLD/CON key. The display will show
either “USA” or “NST”.
4. Press CAL key to toggle between USA and NIST buffer sets.
5. Press HOLD/CON key to confirm.
pH Testing
1. Remove cap from the electrode and press the ON/OFF button to switch tester on.
2. Dip the electrode about 2 to 3 cm into the test solution. Stir once and let the reading stabilize.
3. Note the pH or press HOLD/CON button to freeze the reading. Press HOLD/CON again to release the reading.
4. Press ON/OFF to turn off tester. If you do not press a button for 8.5 minutes the tester will automatically shut off to conser ve batteries.
Reset To Factory Default
You can reset calibration data to factory default settings. This is extremely useful when you want to take a new set of pH measurements or when using a new replacement electrode.
1. With tester off, hold CAL key while pressing ON/ OFF key.
2. The display will show “rSt” flashing.
3. Press HOLD/CON key to confirm. The display
will flash “YES” for 2 seconds and the tester will go back to measurement mode.
4. To exit without confirmation, press CAL key. The display will flash “NO” for 2 seconds and the tester will go back to measurement mode.

Electrode Replacement
You can replace the electrode module at the fraction of the cost of a new tester. When the tester fails to calibrate, gives fluctuating readings in buffers,shows error messages ‘Er1’, ‘Or’ or ‘Ur’ in a buffer, and the procedures in the Maintenance section do not help, you need to change the electrode.
1. With dry hands, grip the ribbed tester collar with electrode facing you. Twist the collar counter clockwise (see picture A). Save the ribbed tester collar and O-ring for later use.
2. Pull the old electrode module away from the tester.
3. Align the four tabs on the new module so that they match the four slots on the tester (see picture B).
4. Gently push the module onto the slots to sit it in position. Push the smaller O-ring fully onto the new electrode module. Push the collar over the module and thread it into place by firmly twisting clockwise.
