Temperature Compensation
In order to get accurate measuring results, we recommend that the standards and samples should be measured at the same temperature. If you need to
enable the temperature compensation, follow the steps below.
Automatic Temperature Compensation
Connect the temperature probe to the meter (Refer to page 4 “Connecting the Sensors”). The ATC icon immediately appears on the display, the meter is now
switched to the automatic temperature compensation mode.
Manual Temperature Compensation
If the meter does not detect a temperature probe, the °C icon will show on the display indicating that the meter is switched to the manual temperature
compensation mode. To set the temperature value of sample, follow the steps below.
1. Press and hold the oCkey for 3 seconds to enter the temperature setting mode.
2. Press the or key to modify the temperature value.
3. Press the Enter key to confirm.
Press the or key once, the setting value will increase or decrease by 0.1. Press and hold the or key, the setting value will increase or

Ion Concentration Calibration
The Bante321 portable ion meter is capable of 2 to 5 points ion calibration with standard solutions, available calibration points include the following options.
MEASUREMENT UNITS
CALIBRATION POINTS
ppm
0.001, 0.01, 0.1, 1, 10, 100, 1000, 10000
mg/L
0.001, 0.01, 0.1, 1, 10, 100, 1000, 10000
mol/L
0.001, 0.01, 0.1, 1, 10
mmol/L
0.001, 0.01, 0.1
In order to get accurate measuring results, we recommend that adding the ionic strength adjuster to all standards and samples. A typical addition would be
2ml ISA to 100ml of standards and samples. If the meter does not calibrated or calibration is not successfully, the display will always show 0.000.
During the calibration, ensure that the selected calibration points cover the anticipated range of the samples.
1.1 Press the Mode key until the meter shows icon.
1.2 If necessary, select the concentration unit and ion valence in the setup menu (Refer to page 5
SETUP MENU).
The meter provides three measurement units, including the ppm, mg/L and mol/L, the factory
default is ppm. If the measurement unit has converted, the display will always show “CAL”and
wait for calibrating the meter.
1.3 Press the Cal key, the meter enters the calibration mode. The display shows 0.001ppm (or
mg/L, mol/L, mmol/L).
1.4 Press the or key to select the calibration point (e.g., 100ppm). The meter will
automatically perform the calibration from the low to high concentrations.

Temperature Calibration
During the measurement process, if the temperature reading displayed differs from that of an accurate thermometer, the meter needs to be calibrated.
1. Connect the temperature probe to the meter and place into a solution with a known accurate temperature.
2. Press and hold the oCkey for 3 seconds to enter the temperature setting mode.
3. Press the or key to set the temperature value.
4. Press the Enter key to confirm. Calibrating is completed.
Ion Concentration Measurement
Before measuring, ensure that the temperature of samples are the same as the standard solutions, the maximum error should be controlled within the 1°C.
For low level measurements or samples contain the interference ions, adding the ionic strength adjuster to sample and using the plastic beaker are
necessary.
1. Press the Mode key until the display shows icon.
2. Rinse the ion selective electrode thoroughly with distilled water. Place the electrode into the sample solution, stir the electrode gently. Record the
measured value when the reading is stable.
mV Measurement
1. Press the Mode key until the meter shows measurement unit “mV”.
2. Rinse the electrode thoroughly with distilled water. Place the electrode into the sample solution. Record the measured value when the reading is
stable.
Auto-Hold
The Bante321 portable ion meter contains an Auto-Hold function. If enabled, the meter will automatically sense a stable reading and lock the measurements,
