1. Push menu , then select STOP ANALYZER.
Note: If START ANALYZER shows, the analyzer is already in standby mode.
2. Push cal , then select FLOW RATE CAL.
3. Wait for the calibration to complete (approximately 5 minutes).
4. Push enter to go to the measurement screen.
5. Push menu , then select START ANALYZER.
5.7 Calibrate the 4-20 mA analog outputs
If an analog output in the analyzer is connected to an external devices, calibrate the analog output as
necessary. The analog outputs are factory-calibrated. The adjustment range for analog output
calibration is ± 2 mA.
Note: If an analog output is configured to be 0–20 mA, 4 mA and 20 mA are calibrated.
1. Push menu , then select SETUP SYSTEM > CONFIGURE ANALYZER > SETUP OUTPUTS >
OUTPUT CALIBRATION > [select an output].
2. Select an option.
Option Description
CAL 4mA With a calibrated digital multimeter, measure the actual value supplied at the analog output.
Adjust the value shown until the signal at the analog output is 4.00 mA.
CAL 20mA With a calibrated digital multimeter, measure the actual value supplied at the analog output.
Adjust the value shown until the signal at the analog output is 20.00 mA.
Section 6 Operation
6.1 Show the details of the current and the last measurement
Push menu and select VIEW DATA > MEASUREMENT DATA. Refer to Table 4 .
Table 4 Measurement data descriptions
Item Description
LAST MEAS TIME The time the last measurement was completed.
LAST MEAS CHANNEL The last channel measured.
NEXT MEAS TIME The time the next measurement will be completed.
NEXT MEAS CHANNEL The next channel to be measured.
SAMPLE TEMPERATURE The temperature of the channel in use.
FLOW RATE The flow rate of the channel in use.
LAST CONC The sodium concentration of the last channel measured.
CONCENTRATION The sodium concentration of the channel in use.
RAW POTENTIAL The real time mV signal. The potential between the two electrodes.
AVERAGE POTENTIAL The six second average (approximately) of the mV signal.
COMPENSATED POTENTIAL The temperature compensated mV value (potential) at 25 °C.
MEAS STABLE Identifies if the measurement is stable (0 to 100). The larger the value, the more
stable the measurement.
pH
4
The adjusted pH of the channel in use.
4
The pH value does not show if the optional cationic pump is installed.
