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 “

”
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 “

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
