3.3. Meter Sockets
The meter is with BNC and RCA sockets, which are protected by grey rubber caps. (As showed in
Chart-2)
Chart-2- Meter sockets
Photos Descriptions
BNC socket (Right) — for pH or ORP probe；
BNC socket (Left) — for Cond. probe；
RCA socket (Middle) — for temperature probe. When both pH probe
and Cond. probe are connected to meter, just plug in temperature
plug of either probe.
3.4. Reading stable display mode
When the measuring value is stable, smiley icon appears on LCD screen,
see Diagram – 3. If the smiley icon does not appear or flash, please do
not get readings or make calibration until the measuring value is
stable. In parameter-setting P1.6, there are 3 criteria for stability:
(Normal), (High) and (Low). The factory default set is “Normal”.
“High” is set for stability for longer time; “Low” is set for stability for shorter
time. User can select suitable stability criteria according to different testing
requirements.

3.5. Auto power-off
The meter will be automatically power-off if nothing is done for 20 minutes. In the parameter setting
menu P6.8, user can set up to turn on or turn off this function.

4. pH measurement
4.1. pH probe information
The meter is equipped with a 201T-F three-in-one combination pH probe, which has built-in temperature
sensor to realize automatic temperature compensation. The BNC plug of the probe is connected to the
pH socket while the RCA plug is connected to the temperature socket. When the probe is immersed in
the solution, please stir the solution briefly to get rid of the air bulb and in this way, a stable measurement
will be reached fast.
4.2. pH calibration related information
4.2.1. Standard buffer solution
Buffer solution selectable: USA series and NIST series, and also user-defined solution. Please refer to
clause 7.3 and select a proper series in parameter setting menu P1.1. Please see Chart - 3 for the two
series of standard buffer solution.

Three-point calibration
4.2.2. Three-point calibration mode
The instrument can perform 1-3 point calibration. In three-point calibration mode, the first point
calibration must use 7.00 pH (or 6.86 pH) standard solution, then select other standard solution to
perform the second and the third point calibration. See chart – 4. During the calibration process, the
instrument displays the probe slope of acidity range and alkalinity range respectively.

4.2.3. Calibration intervals
Calibration intervals depend on the sample, the probe performance, and the required accuracy. For high
accuracy measurements (≤ ±0.02pH), the meter should be calibrated before taking a measurement. For
general accuracy (≥±0.1pH), after one time calibration, the meter can be used for approximately one
week or longer.
The meter must be recalibrated in the following situations:
(a) New probe or probe that is unused for a long period of time
(b) After measuring acids solution (pH<2) or alkaline solutions (pH>12)
(c) After measuring solution that contains fluoride or strong organic solution
(d) If the solution’s temperature differs greatly from that of the calibration solution
4.3. pH meter calibration ( take three-point calibration as an example)
4.3.1. Press key to enter into the calibration mode, “CAL 1” blinks at the
top right of LCD screen and “7.00 pH ”blinks at the bottom right of LCD screen,
indicating using pH 7.00 buffer solution to make the 1
st
point calibration.
4.3.2. Rinse pH probe in pure water, allow it to dry, and submerge it in pH7.00
buffer solution. Stir the solution briefly and allow it to stay in the buffer solution
until a stable reading is reached. The scanning and locking process of buffer
solution will be showed at the bottom right corner of LCD screen. Er 2 will be
showed if press key before the value is locked. See chart – 5.
4.3.3. When the meter locks 7.00 pH, stable icon will appear on LCD screen.
Press key to calibrate the meter. End icon appears after calibration is done.
st
The 1
point calibration is finished, meanwhile, the meter’s display will show at
the top right a blinking CAL2, and show at the bottom right a blinking 4.00pH and
10.01pH alternately, indicating using pH4.00 or pH10.01 buffer solution to make
nd
the 2
point calibration.
4.3.4. Take out pH probe，rinse it in pure water, allow it to dry, and submerge
it in pH4.00 buffer solution. Stir the solution briefly and allow it to stay in the buffer
solution until a stable reading is reached. The meter’s screen will show scanning
and locking process of calibration buffer solution at the bottom right of LCD. When
the meter locks 4.00 pH, stable icon displays on LCD. Press key to
calibrate the meter. End icon and probe slope of acidity range will be displayed
after calibration is done, meanwhile, the meter’s screen will show at the top right
a blinking CAL3, and show at the bottom right blinking 10.01pH, indicating using
pH10.01 buffer solution to make the 3
rd
point calibration.
