Introduction :
We thank you for having purchased Multi Parameter Handheld Meter.
Before using the instrument, please read the operation instructions
carefully, which will help you to operate and maintain the instrument,
as well as to avoid trouble caused by unsuitable operation and
maintenance.
The pocket meter employs leading edge technology with integrated
microprocessor, which is suitable for measurement in water solutions
for institutes, industrial labs and production fields.
Features:
1. Microprocessor based designed.
2. Large LCD displays readings and temperature simultaneously.
3. Rugged design with waterproof housing. It floats on water.
4. Measuring 5 parameters: pH, Conductivity, TDS, Salinity, and
temperature by just on combo electrode.
5. Automatic Temperature Compensation (ATC).
6. Simple to calibrate by one keyboard.
7. Auto power shut off after 10 minutes of non use.
8. Easy replaced electrode module.

Functions of Keyboard :
Choose different function mode.
Press 3 sec. to switch °C/°F
Turn on or off power.
Press 3 sec. to enter calibration mode
Preparation:
1. Remove the protection cap and protection bottle from
the electrode.
2. Rinse the electrode with clean water and wipe it dry.

Calibration:
<pH>
1. Make sure the sensor is 3-in-1 electrode, remove the
soaking bottle, and switch to pH mode.
2. Dip the electrode into the buffer solution pH 7.00. Stir gently
and wait until the reading is stable. Press and hold for
3 sec. to enter calibration mode. The display will appear
CAL and flashing 7.00. When the display stops flashing and
indicates “SA", then "End” while calibration ends, and will
return to measurement mode.
2. Rinse the electrode with clean water and wipe it dry. Dip
the electrode into the buffer solution pH 4.01 as previous
steps.
3. After slope calibration, pH 4.01 or pH 10.01, the display will
indicate the percentage of slope (PTS) to show the status
of the electrode. If the PTS is below 70% or above 130%,
the electrode must be replaced. A slope of 100% is ideal.
Note :
1. Calibration error indicator icon will appear, and “Err” instead
of “SA”, if calibration fails.
2. When doing a 2 or 3 point calibration, Calibrate with buffer
pH 7 first, and then follow with buffer pH 4 or pH 10.
<ORP>
Calibration is not necessary for ORP. However, it could be
tested with specific ORP standard solution to check whether
the electrode is good.

<COND, TDS, Salt>
1. Make sure the probe is 3-in-1 electrode, remove the
soaking bottle, and switch to Conductivity mode.
2. Dip the cell into the standard solution 1413 ì S/cm. Stir
gently and wait until the reading is stable. Press and hold
for 3 sec. to enter calibration mode. The display
will appear CAL and flashing 1413ì S/cm. When the
display stops flashing and indicates “SA", then "End” while
calibration ends, and will return to measurement mode.
Note :
1. Calibrated by 12.88 mS/cm standard solution would be
better for measuring high conductivity solution.
2. Calibration error indicator icon will appear, and “Err”
instead of “SA”, if calibration fails.
3. If the reading is not 0 ì S/cm while the electrode is in the
air and not dipped into any solution, calibrate it in the air
to make reading become 0 ì S/cm.
4. The calibration points of Conductivity are 0, 84 ì S/cm,
1413 ì S/cm, 12.88 mS/cm and 80.0 mS/cm.

Measurement :
<pH>
1. Press to choose pH mode.
2. After calibration, rinse the 3-in-1 electrode with clean water and
wipe it dry. Dip the electrode into the sample solution which is
going to be measured. Stir gently and wait until a stable reading
can be obtained.
Note :
1. The display will appear “----” when it is over measuring range.
2. After measurement, rinse the pH or ORP electrode with clean
water. Replace the soaking bottle. The soaking bottle should be
always filled with soaking solution.
<ORP>
1. Insert ORP electrode, and press to choose ORP mode.
2. Rinse the ORP electrode with clean water and wipe it dry. Dip
the electrode into the sample solution which is going to be
measured. Stir gently and wait until a stable reading can be
obtained.

<COND, TDS, Salt>
1. Presse to choose COND, TDS or Salt mode.
2. After calibration, rinse the 3-in-1 electrode with clean water
and wipe it dry. Dip the electrode into the sample solution
which is going to be measured. Stir gently and wait until a
stable reading can be obtained.
Note :
1. The display will appear “----” when it is over measuring range.
2. The units will auto-range to ì S/cm or mS/cm, or ppm or ppt.
3. After measurement, rinse the cell with clean water and replace
the protective cap.
4. Don't touch or wipe the surface of the inner black plate of the
conductivity cell.

Battery Change :
1. Please loosen the collar, and remove the electrode.
2. Lift the battery cap to open it.
3. Please mind the polarity of the batteries when install
them into the meter.
