Meter Overview

Preparation

The pH electrode is shipped dry. Before using the Checker^®, remove the protective cap and condition the electrode by soaking the tip (bottom 4 cm (1.5″)) in pH 7.01 buffer solution for several hours. Then follow the calibration procedure.

• Do not be alarmed if white crystals appear around the cap. This is normal with pH electrodes and they dissolve when rinsed with water.
• Connect the electrode to the meter.
• Turn the Checker^® on by pressing ON/OFF button.
• Remove the protective cap and immerse the tip of the electrode in the sample to be tested.
• Stir gently and wait for a stable reading.

NEVER IMMERSE THE ELECTRODE OVER THE MAXIMUM IMMERSION LEVEL. THE CONNECTOR MUST ALWAYS BE CLEAN AND DRY.

• After use, rinse the electrode with water and store it with a few drops of HI70300 storage solution in the protective cap.
• Replace protective cap after each use.

DO NOT USE DISTILLED OR DEIONIZED WATER FOR STORAGE PURPOSES.

Specifications

Operation

Press the ON/OFF button to turn the meter on. All tags will be displayed.

The meter will go into measurement mode: current reading and calibrated buffers are displayed.

Auto-off

From measurement mode, press and hold the ON/OFF button. The meter will cycle through «OFF,» «CAL,» then current auto-off setting.

The default setting is 8 minutes («d08»). Press ON/OFF button to change. «d60» is auto-off after 60 minutes, and «d—» disables the auto-off feature. Press and hold the button to exit the menu.

Clear Calibration

Place meter in calibration mode. Press and hold ON/OFF until «CLr» is displayed. The meter will now be at default calibration. No tags will be shown in measurement mode until calibration is performed.

«Err» Message

In calibration mode, if the meter displays an «Err» message when in the correct fresh buffer solution then the probe should be cleaned. Place the probe in the HI700601 cleaning solution for 15 minutes. Rinse with purified water and place in storage solution for 1 hour before calibrating. If the «Err» message persists then the HI1271 probe should be replaced.

Battery Indicator

The Checker^®features a low battery indicator. When the battery is running low, the tag will blink on screen. When the battery has been depleted, «Erb» will appear on screen and the meter will turn off.

Meter Calibration

From measurement mode, press and hold the ON/OFF button until «CAL» is displayed.

When «7.01» blinks on the display, place the tip of the probe into a pH 4.01, 7.01, or 10.01 buffer solution.

For one or two-point calibration using pH 7.01 buffer go to procedure A

For one-point calibration using pH 4.01 or pH 10.01 buffer go to procedure B

One or Two-Point Calibration with pH 7.01

If pH 7.01 buffer solution is used as the first point the buffer is recognized with the blinking stability indicator.
When the reading is stable, the stability indicator will disappear and pH 7.01 will be calibrated.
If pH 7.01 is the only calibration point, finish one-point procedure at right.
If using pH 4.01 or pH 10.01 as a second point, continue two-point procedure at right.

One-Point

1. 
   pH 4.01 will then blink on the dispaly.
2. 
3. 
   Meter will exit to measurement mode and the calibration tag will be displayed

Two-Point

1. 
   Use pH 4.01 or pH 10.01 to perform a two-point calibration. The value is automatically recognized and displayed with the blinking stability indicator.
2. 
   When the reading is stable, the stability indicator will disappear. «Sto» will be displayed when the calibration is saved.
3. 
   Meter will exit to measurement mode and the calibration tags will be displayed.

One-Point Calibration with pH 4.01 or pH 10.01

1. 
   If pH 4.01 or pH 10.01 buffer solution is used as the first point the value of the buffer is recognized and displayed with the blinking stability indicator.
2. 
   When the reading is stable, the stability indicator will disappear.»Sto» will be displayed when the calibration is saved.
3. 
   Meter will exit to measurement mode and the calibration tag will be displayed.

Care and Maintenance

To obtain the highest accuracy for measurements it is important to follow these tips:

• Calibration is only as good as the buffer being used. The pH buffer values change over time once the sachets are opened. Fresh buffer should be used for each calibration.
• The probe should be rinsed with purified water each time before placing in buffer or sample to be tested.
• When the meter is not in use it is important to add several drops of storage solution to the protective cap to keep the probe hydrated. If storage solution is not available, pH 4.01 or pH 7.01 buffer can be used.
• For improved accuracy it is recommended to calibrate to a minimum of two points. It is important to use buffers that bracket the expected value of the sample to be tested. For example, if the expected value is pH 8, the meter should be calibrated using pH 7.01 and pH 10.01 buffers.
• It is important to calibrate and measure samples at the same temperature. A dramatic change in temperature between buffer solutions and samples to be tested will give inaccurate readings.

Battery Replacement

To change the CR2032 Li-ion battery, turn the battery cover located on the back of the meter counterclockwise to unlock. Remove cover and replace with + side facing up.

Note: Batteries should only be replaced in a safe area using the battery type specified in this instruction manual. Old batteries should be disposed in accordance with local regulations.

Recommendations for Users

Before using Hanna Instruments products, make sure that they are entirely suitable for your specific application and for the environment in which they are used. Any variation introduced by the user to the supplied equipment may degrade the meter’s performance. Avoid touching the electrode area. To avoid damages or burns, do not put the meter in microwave oven. For yours and the meter’s safety do not use or store the meter in hazardous environments.
