11ï Enter a 4-digit value using the arrow keys.ï Press the ALT and CFM keys to confirm the value.Item CHr - Battery level testï Select item CHr.ï The LCD will display "bAtt" and the remain-ing percentage of battery charge (100%means fully charged battery and 0% corre-sponds to the minimum battery voltagethat allows the meter to operate).Note: The battery level test is also performed each time the meter isturned on.Connect pH electrode and temperature probeto the meter and press the ON/OFF key topower on the instrument.If necessary, press the RANGE key until thedisplay enters the pH mode.For greatest accuracy, it is recommended to setthe calibration alarm time-out to the appro-priate value for the specific use and calibratethe meter as soon as the "CAL" and "DATE"symbols blink on LCD (see GLP section).To take pH measurements, remove the elec-trode protective cap and simply submergethe bottom 4 cm (1Ω") of the electrode andthe temperature probe in the solution to betested. Allow for the reading to stabilize.Note: To better use the meter ATC capability, it is recommended toposition the temperature probe as close as possible to the pHelectrode.The temperature is displayed on the lower LCD.The pH reading is temperature compensated.If the meter displays "----" the reading is out of range, while ablinking reading means that the electrode is "dead".By pressing the RANGE key the meter will switch between pH and mVreading. The mV scale is autoranging: when the reading is outside±600mV the decimal point automatically disappears.TAKING pH MEASUREMENTSON / OFF22LCD BACKLIGHTThe LCD can be illuminated to allow the user to see the readings evenin dark environments.It can be enabled/disabled through the LIGHTkey and it is automatically disabled when batter-ies are in low battery condition.Two levels (low and high) of backlighting can be selected. Repeatedlypressing the LIGHT key causes the lighting to cycle from off to low thento high intensity.Note: It is not possible to enable backlight in low battery condition;the "Batt" indication will be displayed when trying to do so.LIGHT DELSPECIFICATIONS:Isolated 8-bit data transmissionBaud Rate: 2400Start bit: 1Stop bit: 1Parity bit: noneDATA TRANSFER TO PCON / OFFALTLIGHTHI 98160Microprocessor Logging pH/ORP MeterLOGRANGECALBefore starting the serial communication, please put the meter inmeasurement mode (pH or mV mode). Connect the meter to a PCthrough the RS232 output (the connector is located on the top of themeter). Use HI920011 (5 to 9-pin) connection cable.ï Press the RANGE key to scan remaining data, in the following order:last calibration timefirst calibration pointsecond calibration pointthird calibration pointï The meter will then return to normal operating mode. Press theALT and GLP keys to escape before viewing all the data.
