Instruction Manual pH 5+, pH 6+, Ion 6+ 1. INTRODUCTION Thank you for purchasing the pH 5+, pH 6+, or Ion 6+ meter. These microprocessorbased 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). The pH 6+ and Ion 6+ meters measure pH, mV (ORP) and temperature. Additionally, the Ion 6+ allows direct ion concentration measurement of various ions (mono and divalent).
Instruction Manual pH 5+, pH 6+, Ion 6+ 2. GETTING STARTED 2.1 Description of Keypad Functions The pH 5+ and pH 6+ have four keys while the Ion 6+ meter has six keys on its splashproof keypad. The common keys are ON/OFF, HOLD/ENTER, CAL and MODE. The Ion 6+ meter adds S and T keys. ON/OFF: Powers meter on and off. Meter starts up in the mode that you last switched off from. MODE/INC: Selects measurement mode for Ion, mV, pH and Temperature. Increment button for mV calibration (pH 6+ only).
Instruction Manual pH 5+, pH 6+, Ion 6+ 2.2 Description of LCD Annunciators The large custom LCD consists of 3½-digit segments which uses annunciators for pH, o mV or C (Temperature). No annunciator is shown in Ion mode. Other annunciators include “HO” (when HOLD function is activated) and “LO” (low battery condition). 2.3 Inserting & Removing the Rubber Armor / Stand 1. To remove meter from rubber armor, push out from the bottom edges of meter until it is completely out of boot.
Instruction Manual pH 5+, pH 6+, Ion 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. 2.5 Battery Replacement The “LO” annunciator of the LCD alerts you when battery power is running low. Caution: Power off the meter before changing battery. 2.
Instruction Manual pH 5+, pH 6+, Ion 6+ BNC connector of pH, ORP, or Ion electrode 2.5 mm Phono plug for temperature measurement 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.
Instruction Manual pH 5+, pH 6+, Ion 6+ 3. CALIBRATION 3.1 pH Calibration The meter is capable of calibrating up to 3 pH values using USA or NIST (nSt) pH buffer standards or 2 pH values with Low Ionic (Pb) pH buffer standard. All new calibration values will automatically override existing data. USA group 4.01, 7.00, 10.01 NIST group 4.01, 6.86, 9.18 Pb group 4.10, 6.97 o For best results perform at least a 2-point calibration at room temperature (25 C) using standard buffers. Begin with pH 7.
Instruction Manual pH 5+, pH 6+, Ion 6+ 3. Press CAL to enter pH calibration mode. “CA” displays momentarily before the display flashes the current un-calibrated reading. 4. To abort or cancel calibration without accepting the new value, press CAL key. The meter will automatically revert to pH measurement mode. 5. Allow reading to stabilise if necessary. Press ENTER key to confirm calibration. “CO” displays momentarily before reverting to pH measurement mode. 6.
Instruction Manual pH 5+, pH 6+, Ion 6+ Press ENTER key to confirm your selection. The meter will automatically revert to pH measurement mode. The meter will save the selected group indefinitely until changed. 3.1.3 Resetting User Calibrated Values The calibrated pH/mV/Ion values can be reset to factory default using the procedure below. Temperature offset will not be reset using this procedure. To abort press CAL to revert to measurement mode. 1.
Instruction Manual pH 5+, pH 6+, Ion 6+ available include 0.1, 1.0, 10.0, 100.0 ppm. Recalibrate and ensure that consecutive calibration points are 1 decade apart from each other. Ensure that you use new or fresh standard solutions during calibration. Do not reuse ion standard solution as it may be contaminated and affect the calibration and accuracy of measurements. Store standard solutions in a dry, cool environment if possible.
Instruction Manual pH 5+, pH 6+, Ion 6+ 3. Press ENTER to confirm that the ppm value is the desired standard. The displayed value now shows the corresponding mV reading for the selected ppm value selected. Allow the reading to stabilise. st 4. When the mV reading is stable, press ENTER to complete the 1 point calibration. The display will show the next highest calibration standard value. Rinse the electrode with clean water. 5. Dip the electrode into your next highest standard solution.
Instruction Manual pH 5+, pH 6+, Ion 6+ If the calibration is not successfully stored into its memory, an error message “Er3” will be displayed. This occurs when the slope is lower than 15mV/decade or higher than 90mV/decade. 3.3 Millivolt (mV) Calibration (pH 6+ only) mV calibration is performed for Oxidization Reduction Potential (ORP / Redox) measurements, where you can adjust its mV value as a base value for measurements. To abort press CAL to revert to measurement mode. 1.
Instruction Manual pH 5+, pH 6+, Ion 6+ 3.4 Temperature Calibration 3.4.1 With Temperature Probe The temperature probe (ECPH5TEM01P) 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. Press MODE key to enter the o Temperature mode until “ C” annunciator appears in the LCD. 2.
Instruction Manual 3.4.2 pH 5+, pH 6+, Ion 6+ Without Temperature Probe (no ATC) If no temperature probe is used, the meter compensates for pH response based on a o 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. Press CAL key to enter temperature calibration mode.
Instruction Manual pH 5+, pH 6+, Ion 6+ 4. MEASUREMENT 4.1 Taking Measurements 1. Before measurement, rinse pH/ORP electrode or Ion Selective Electrode and temperature probe with clean water to remove any impurities stuck onto the bodies of probes. 2. Power on the meter using ON/OFF key. Press MODE key to select your desired mode of operation (pH, mV, Ion, or Temperature). 3. Dip and stir both probes gently into an aqueous test sample, swirl gently and wait for the reading to stabilise. Note the reading.
Instruction Manual pH 5+, pH 6+, Ion 6+ 5. ELECTRODE CARE AND MAINTENANCE For best results, keep the ISE capped dry and pH/ORP electrode bulb wet. Store the pH/ORP glass bulb with pH electrode storage solution. NEVER use deionised water for storage. Wash electrodes with clean water after each use. Your ISE or pH electrode is susceptible to contamination or dirt. Clean as needed using mild detergent and warm water. Blot the probe gently with a soft tissue paper.
