Wait for a few minutes for the temperature sensor to reach
thermal equilibrium, when the tag disappears. The LCD
displays the EC or TDS value (automatically compensated
for temperature) on the secondary LCD, while the third LCD
displays the sample temperature.
HOLD MODE
While in measurement mode, press and hold the SET
button until “HOLD“ appears on the third LCD line for
1 second. The measurement reading will be frozen on the
LCD with “H” blinking.
Press any button to resume active measurements.
pH CALIBRATION
Select calibration type “STD“ from SETUP. Place the
sensor into the first calibration buffer. If performing a two‑point
calibration, use pH 7.01 buffer first. The meter will enter the
calibration mode, displaying “pH 7.01 USE” and
tag blinking.
SINGLE-POINT pH
1. Place the probe in any buffer from
the selected buffer set. The meter
will automatically recognize the buffer value.
2. If the buffer is not recognized or the calibration offset is
out of the accepted range “---- WRONG“ is displayed.
3. If the buffer is recognized “REC“ is displayed then
“WAIT“ until the calibration is accepted.
If using pH 7.01, after acceptance of the buffer press any
key to exit. The ”SAVE” message is displayed and the meter
returns to pH measurement mode.
If using pH 4.01 or 10.01 buffer the ”SAVE” message is
displayed and meter returns to pH measurement mode.
TWO-POINT pH
Proceed with steps 1 through 3 under single point calibration
using 7.01 pH buffer first. Then follow steps below:
