INTRODUCTION Thank you for selecting this meter. The waterproof pH 300/310 Hand-held meter is a microprocessor-based instrument that is designed to be handy and user-friendly. It is capable of measuring pH, mV and temperature. It is designed to be handy and capable of allowing one-hand operation. -
Page 5: Display And Keypad Functions
DISPLAY AND KEYPAD FUNCTIONS Display The LCD has a primary and secondary display. • The primary display shows the measured pH, mV or Relative mV value. • The secondary display shows the measured temperature. display also shows error messages, keypad functions program functions. -
Page 6: Keypad
Keypad The large membrane keypad makes the instrument easy to use. Each button, when pressed, has a corresponding graphic indicator on the LCD. See Figure 2. Some buttons have several functions depending on its mode of operation. Function Powers on and shuts off the meter. When you switch on the meter, the meter starts up in the ON/OFF mode that you last switched off from. -
Page 7: Inserting The Batteries
Inserting the Batteries Four AAA batteries are included with your meter. Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure 3 below. Remove battery cover to expose batteries. Insert batteries. Follow the diagram inside the cover for correct polarity. Replace the battery cover into its original position using the two screws removed earlier. -
Page 8: Connecting The Electrode And Temperature Probe
Connecting the Electrode and Temperature Probe The waterproof pH 300/310 handheld pH meter uses any standard pH, ORP, or ISE electrode with a BNC connector. For Automatic Temperature Compensation (ATC), this meter requires a temperature probe with a special 6-pin connector. Use either: •... - Page 9 Figure 4 - Connection for pH Electrode (BNC) and Temperature probe (6-pin connector)

Page 10: Attaching The Electrode Holder To The Meter
Attaching the Electrode Holder to the Meter The waterproof pH 300/310 handheld meter comes complete with two electrode holders. They are designed to facilitate one-hand operation. Attach two electrode holders if you have a separate electrode and temperature probe. Care must always be taken to avoid use of excessive force in the process of attaching these components. -
Page 11: Calibration
CALIBRATION Important Information on Meter Calibration When you re-calibrate your meter, old pH, Rel mV and mV calibration points are replaced on a point by point basis. For example, if you previously calibrated your meter at pH 4.01, 7.00, and 10.01, and you have now re-calibrated at pH 7.00, the meter retains the old calibration data at pH 4.01 and pH 10.01. - Page 12 pH 300 meter calibration The pH 300 meter is capable of up to 5-point pH calibration to ensure accuracy across the entire pH range of the meter. Select from the following buffer options: • USA buffers --- pH 1.68; 4.01, 7.00, 10.01, and 12.45. The meter automatically recognizes and calibrates to these standard buffer values, which makes pH calibration faster and easier.
-
Page 13: Ph Calibration
pH Calibration NOTE: We recommend that you perform at least 2-point calibration using standard buffers that bracket (one above and one below) the expected sample range. You can perform a 1-point calibration, but make sure that the buffer value is close to the sample value you are measuring. - Page 14 Rinse the probe with de-ionized water or a rinse solution, and place it in the next pH buffer. Follow steps 5 and 6 for additional calibration points. See Figure 9. When all the calibration points as set in the Unit Configuration Setup (see P4.2 on page 31) are completed, the meter returns to Measurement mode automatically.
-
Page 15: Relative Mv Calibration
Relative mV Calibration While in the measurement function, press MODE to enter the mV mode. The mV indicator appears in the upper right hand corner. See figure at right. Press the CAL/MEAS key. The CAL indicator appears above the primary display. The primary display shows the relative mV reading and the secondary display shows the absolute mV value. -
Page 16: Temperature Calibration
Temperature Calibration The temperature sensor is factory calibrated. Calibrate the temperature probe only if you suspect temperature errors that may have occurred over a long period of time or if you have a replacement probe. Temperature Calibration Make sure the ATC probe (or temperature connector of the electrode) is attached to the 6-pin connector. -
Page 17: Measurement
MEASUREMENT This meter is capable of taking measurements with automatic or manual temperature compensation. Automatic temperature compensation only occurs when a temperature sensor is plugged into the meter. If there is no temperature sensor plugged into the meter, the default manual temperature setting is automatically 25 °C. -
Page 18: Manual Temperature Compensation
Manual Temperature Compensation IMPORTANT: For manual compensation, you must disconnect the temperature probe (see page 6). Switch the meter on. Press the MODE key to select pH mode. Press the CAL/MEAS key to enter pH calibration mode. The CAL indicator will appear above the primary display. -
Page 19: Taking Measurements
Taking Measurements Be sure to remove the electrode soaker bottle or protective rubber electrode before measurement. To take readings: Rinse the probe with de-ionized or distilled water before use to remove any impurities adhering to the probe body. If the pH electrode has dehydrated, Figure 15 - Measurement mode soak it for 30 minutes in electrode storage solution or 2M –... -

MEMORY FUNCTION Memory Input Your meter stores data in sets: • pH and temperature • mV (or relative mV) and temperature For pH 300 meter: The pH 300 meter can store up to 16 sets of data in any combination of values. -
Page 22: Memory Recall
Memory Recall This function recalls the previous readings stored in the memory. You can only access MR from the measurement mode. Memory recall is in “Last In First Out” order. To recall readings: Press the MR key once to retrieve the last reading stored. - Page 23 If necessary, press the MI/▲ key to select the next “memory location” screen; press the MR/▼ key to select the previous “memory location” screen. Repeat steps 2 to 5 to review additional stored data sets. To exit Memory Recall, press the MEAS key to return to the Measurement mode.

Page 41: Probe Care And Maintenance
PROBE CARE AND MAINTENANCE Since your pH electrode is susceptible to dirt and contamination, clean it every one to three months depending on the extent and condition of use. NOTE: For specialty electrode care, consult the instruction manual included with your electrode. pH electrode storage For best results, always keep the pH bulb wet. - Page 42 Reactivating the pH electrode If stored and cleaned properly, your pH electrode should be ready for immediate use. However, a dehydrated bulb may cause sluggish response. To rehydrate the bulb, immerse the electrode in a pH 4 buffer solution for 10 to 30 minutes. If this fails, the electrode requires activation. Never touch or rub glass bulb.
