MW180 pH / mV / EC / TDS / NaCl / Temperature Bench Meter
3. After the first calibration point has been confirmed, the calibrated value is displayed
on the first LCD line and the second expected buffer value on the third LCD line
(i.e. pH 4.01). The value of the first buffer is set while the second expected buffer value
is displayed blinking on the screen.
For one-point calibration, press CAL/EDIT to exit calibration. The meter stores the
calibration and returns to Measurement mode.
To continue calibrating with additional buffers, rinse and place the pH probe tip
approximately 4 cm (1 ½”) into the second buffer solution and stir gently.
If needed, use the
keys to select a different buffer value.
Note:
When attempting to calibrate with a different buffer (not yet used), the previously
used buffers are displayed blinking.
Follow the same steps for 2- or 3-point calibration.
Calibration procedure can be continued up to 5-point following the same steps.
Press CAL/EDIT to exit calibration. The meter stores the calibration and returns to
Measurement mode.
For improved accuracy, a minimum of 2-point calibration is recommended.
Note:
When performing a new calibration (or adding to an existing calibration) the
first calibration point is treated as an offset. Press CAL/EDIT after the first or second
calibration point has been confirmed, and the instrument stores the calibration data
and returns to Measurement mode.
Custom Buffers
This feature has to be enabled in Setup. Temperature compensation of custom buffers is
set to the value of 25°C.
Calibrating with custom buffers:
y
Press RANGE/
. The custom buffer value is blinking on the third LCD line.
y
Use the
keys to modify the value based on the temperature reading. The buffer
value is updated after 5 sec.
