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.
The pH 5+ measures pH and temperature (oC). 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). The mV mode is also useful for diagnosis of ion selective electrodes (ISE).
Meters include 4 alkaline “AAA” batteries, a rubber armor / stand, instruction manual, and warranty card. Please refer to Section 8 Replacements and Accessories for information on additional accessories and calibration solutions.

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).
CAL: Allows calibration for Ion, pH, mV or Temperature, or to abort calibration and return to measure without confirming a value.
S (Ion 6+ only): Increment values during calibration mode.
T (Ion 6+ only): Decrement values during calibration mode.
HOLD: Freezes the measured reading for easy viewing.
ENTER: Confirms calibration value.

2.2 Description of LCD Annunciators
The large custom LCD consists of 3½-digit segments which uses annunciators for pH, mV or oC (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. Ensure that cables of ISE/pH electrode or temperature probe are not connected. Figure A.

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.
2.6 Connecting the Electrode and Temperature Sensor
To connect the electrode into meter, align the BNC connector slots with the posts of meter’s socket and rotate connector clockwise until it locks. Do not force when connecting. To remove, simply rotate the connector in counter-clockwise direction until it unlocks, and slide the connector off the socket.
