INTRODUCTION

This simple and easy to use waterproof

pH Pen measures from 2~12 pH.

DISPLAY / FACEPLATE

CALIBRATION

 Calibrate routinely before use, an-

ytime the readings seem erratic, and

whenever the batteries are replaced.

 Remove the protective cap.

 Clean the electrode with de-ionized/

distilled water. Note: Crystals may

form in the cap and these can be

soaked or rinsed away. Do not touch

or rub the glass bulb.

 Before first use or after extended

storage, soak the electrode in

distilled water for 10~30 minutes.

 Press >1 sec to turn on the unit.

 For 1-point calibration, dip/stir the

electrode into pH 7 buffer solution

and press the button. If the

probe is damaged or cannot detect

the buffer, the unit automatically exits

calibration mode after 10 seconds.

 During calibration, "CA" flashes on

the display.

 Then, "CAL" and the pH value are

shown.

 "SA" (save) is displayed as the

calibration point is saved.

 "En" (end) displays when the

calibration ends.

 For 2 or 3 point calibration, start with

pH 7, then repeat the above steps for

pH 4 and/or pH 10.

 For highest accuracy, calibrate at the

sample temperature.

 Repeat the above procedures until

readings stabilize.

 NOTE: If the buffer value is not

standard (for example 4.2), press ▲

to adjust the displayed value.

"SA" (save) is displayed, followed by

"En" (end).

MEASUREMENT

 Calibrate the pen as needed.

 Remove the protective cap and clean

the electrode with de-ionized/distilled

water. Do not touch the glass bulb.

 Press >1 sec to turn on the unit.

 Dip/stir the electrode into the sample.

 The pH value is displayed.

 "- -

" is displayed when the pH

sample is out of range.

 During measurement, press ▲ to

freeze the reading on the LCD.

"Hold" is displayed. Press ▲ again to

return to normal measurement.

 The pH Pen automatically shuts off

after 20 minutes of inactivity. To

disable this feature, start with the unit

off, then simultaneously press the

and ▲ buttons. Release both buttons

when "n" is displayed. The unit

returns to measurement mode.

 After use, turn off the unit and rinse

the electrode.

 Protect the electrode's lifespan by

adding a few drops of KCL (potassium

chloride) solution into the protective

cap before storage.

 Always keep the protective cap on

when the unit is not in use.
