Instruction Manual pH 5/6 & Ion 5/6 1. INTRODUCTION Thank you for purchasing pH 5/6 or Ion 5/6 meter series. These microprocessor-based handheld meters are economical and easy to use. It has a large custom LCD (Liquid Crystal Display) for clear and easy reading. o The pH 5 measures pH and temperature ( C) while the pH 6 measures pH, mV (ORP) and temperature. Ion 5/6 allows Ion concentration measurement of various ions (mono and di o valence) and mV.
Instruction Manual pH 5/6 & Ion 5/6 2. GETTING STARTED 2.1 Description of Keypad Functions pH 5/6 has four keys and Ion 6 meter has six keys on its splash-proof keypad with tactile feedback. The common keys include ON/OFF, HOLD/ENTER, CAL and MODE keys. Ion 5/6 meter has additional and keys. ON/OFF: Powers meter on and off. Meter starts up in the mode that you last switched off from. MODE: Selects measurement mode for Ion, mV, pH and Temperature.
Instruction Manual pH 5/6 & Ion 5/6 2.2 Description of LCD Annunciators The meter has a large custom LCD that consists of 3½-digit segments and o operation annunciators for pH, mV or C (Temperature). Note that there is no annunciator shown in Ion mode. Other annunciators include “HO” (when the HOLD function is activated) and “LO” (low battery condition). 2.3 Inserting & Removing the Rubber Boot 1.
Instruction Manual pH 5/6 & Ion 5/6 2.4 Inserting New Batteries The battery compartment is found at the back of instrument. To open the battery compartment, push in the direction of arrow and lift up the cover. Note the polarity of battery before inserting into position. After replacement, place cover back and press down until it locks tight. 2.5 Battery Replacement A “LO” annunciator in the LCD alerts you when battery power is running low. Replace with the same type as recommended by the manufacturer.
Instruction Manual pH 5/6 & Ion 5/6 BNC of pH/ORP electrode or ISE Phono jack of Temperature probe Insert the mini phono jack of temperature sensor into the socket on the meter. Unplug the phono jack when not in use or you measure pH without any temperature compensation. 2.7 Condition the pH Electrode Condition the pH electrode before use or if it has not been in use for a long time by soaking it into a container filled with pH 4 buffer solution for at least 1 hour.
Instruction Manual pH 5/6 & Ion 5/6 3. CALIBRATION 3.1 pH Calibration The meter is capable of calibrating up to 3 points using USA or NIST (nSt) pH buffer standards or 2 points with Low Ionic (Pb) pH buffer standard. All new calibration values will automatically override existing data. USA pH 4.01, 7.00 and 10.01 NIST pH 4.01, 6.86 and 9.18 Pb pH 4.10 and 6.
Instruction Manual pH 5/6 & Ion 5/6 3.2 Selection of pH buffer standards You must set the meter to accept either USA, NIST (nSt) or Low Ionic (Pb) pH buffer standard values before calibration. The factory default is USA standard. If you wish to abort this operation press the CAL key at any sequence and the meter reverts to pH measurement mode. 1. Press and hold the MODE key. Switch on the meter using ON key. The display shows “bUF” blinking. 2. Press ENTER key to get into its buffer selection mode.
Instruction Manual 3.2.2 pH 5/6 & Ion 5/6 pH Calibration using USA standard buffers 1. Pour a known pH buffer standard solution into a clean, dry container, e.g. pH 7.00. Power on the meter and it automatically enters into measurement mode. Select pH mode by pressing MODE key if necessary. 2. Dip both pH electrode and temperature probe into pH 7.00 buffer solution. Swirl gently and wait for reading to stabilise (approx. 30 seconds depending on your electrode condition). 3.
Instruction Manual 3.2.3 pH 5/6 & Ion 5/6 pH Calibration using NIST standard buffers 1. Pour a known pH buffer standard solution into a clean container, e.g. pH 6.86. Power on meter, and it automatically enters into measurement mode. Select pH mode by pressing MODE key if necessary. 2. Dip both pH electrode and temperature probe into pH 6.86 buffer solution. Swirl gently and wait for reading to stabilise (approx. 30 seconds depending on your electrode condition). 3.
Instruction Manual 3.2.4 pH 5/6 & Ion 5/6 pH Calibration using Pb standard buffers 1. Pour a known pH buffer standard solution into a clean container, e.g. pH 6.97. Power on meter, and it automatically enters into measurement mode. Select pH mode by pressing MODE key if necessary. 2. Dip both pH electrode and temperature probe into pH 6.97 buffer solution. Swirl gently and wait for reading to stabilise (approx. 30 seconds depending on your electrode condition). 3.
Instruction Manual pH 5/6 & Ion 5/6 3.3 Ion Calibration (Ion 5 and 6) The Ion 5/6 meter is capable of up to 3-point ion calibration (minimum 2 point) with standard solutions to ensure accuracy across the entire range of the meter. To exit calibration after you have first entered into ion calibration, press CAL key again. No ion calibration values are stored into the meter’s non-volatile memory.
Instruction Manual 3.3.1 pH 5/6 & Ion 5/6 Multi-point Ion Calibration 1. In case if you need to start calibration using 1.0 ppm standard solution, you can skip the 0.1 ppm calibration option (as mentioned * below). 2. For this instance let’s take 1.0 ppm calibration. To begin, pour a known 1.0 ppm standard solution into a clean container. Power on the meter, and set the meter to Ion measurement mode. 3. Dip the ISE into 1.0 ppm standard solution. Swirl it gently.
Instruction Manual pH 5/6 & Ion 5/6 nd 9. Press ENTER key to confirm 2 point calibration (e.g. 10.0 ppm) and the display will show the next calibration option, 100.0 ppm. To exit from 2-point calibration, press CAL key and the LCD shows “PXX mV” momentarily which is the ISE slope in mV value. The meter then reverts to ion measurement mode. The calibration values are successfully stored into its memory.
Instruction Manual pH 5/6 & Ion 5/6 3.4 Millivolt (mV) Calibration (for pH 6 only) mV calibration is performed for ORP or Redox measurements, where you can adjust its mV value as a base value for measurements. 1. Press MODE key to enter mV mode, the LCD displays “mV”. 2. Dip the ORP electrode into a known standard solution, e.g. Quinhydrone 255 and swirl it until the reading stabilizes. 3. Press CAL key to enter mV calibration. The LCD shows “CA” momentarily followed by displayed reading flashes. 4.
Instruction Manual pH 5/6 & Ion 5/6 3.5 Temperature Calibration 3.5.1 With Temperature probe The temperature probe (EC-PH5-TEM01P/ 35613-05) provided with the meter is factory-calibrated. Over time, temperature calibration may drift and require calibration. If there is a need to replace with the new probe you should calibrate the temperature probe prior to pH calibration. 1. Connect your temperature probe to the meter.
Instruction Manual 3.5.2 pH 5/6 & Ion 5/6 Without Temperature probe (no ATC) If no temperature probe is used, the meter compensates for pH response based on a o new calibrated temperature value manually set by you or at 25.0 C (factory default). o 1. Press MODE key to enter into Temperature mode until “ C” shows in LCD. 2. Compare the displayed value to NIST certified thermometer or thermometer known to be accurate (dipped into a constant temperature bath). 3.
Instruction Manual pH 5/6 & Ion 5/6 4. MEASUREMENT 4.1 Taking Measurements 1. Before measurement, rinse pH/ORP electrode or Ion Selective Electrode (ISE) and temperature probe (except Ion 5) thoroughly with tap or distilled water to remove any impurities stuck onto the bodies of probes. 2. Power on the meter using ON key. Press MODE key to select your desired mode of operation (pH, mV, Ion or Temperature). 3.
Instruction Manual pH 5/6 & Ion 5/6 5. ELECTRODE CARE AND MAINTENANCE For best results, always keep the ISE capped dry and pH/ORP electrode bulb wet. Store the pH/ORP glass bulb with pH electrode storage solution. Other pH buffers are also suitable. NEVER use deionised water for storage. Wash the probes thoroughly with distilled water after each use. Because your ISE or pH electrode is susceptible to contamination or dirt, clean it every 1 to 2 months depending on extent and condition of use.
