GENERAL DESCRIPTION AND INTENDED USE

The HI99192 portable pH meter together with a FC2153 combination pH electrode, is designed to measure pH of potable water.
The HI99181 is a lightweight, portable pH and temperature meter. It has a two button operation system and is simple to use. The HI99181 has a waterproof and compact casing, large dual‑line display, and automatic pH calibration at one or two points.
The FC2153 has three ceramic junction providing for 40 to 50 μL/hour of electrolyte flow. This increased flow provided a greater continuity between the reference electrode and the pH electrode making it suitable for water of low ionic strength. To optimize the flow from the electrode the refill cap should be unscrewed so that it is open. This allows for positive head pressure to be created allowing for the electrolyte to flow more easily into the sample.
The FC2153 has a built‑in temperature sensor for temperature compensated pH readings and an integrated preamplifier to provide measurements impervious to noise and electrical interferences.

MAIN FEATURES

• Simultaneous pH and temperature measurements on a large dual‑line LCD display
• Automatic pH calibration at one or two points within two memorized buffer sets (standard or NIST)
• Selectable temperature unit (°C or °F)
• Electrode condition indicator
• mV of pH measurement for electrode check
• FC2153 dedicated pH probe with integrated temperature sensor
• Probe quick connect system
• Battery life indication and low battery detection
• Keystroke confirmation tone
• Auto‑off function

OPERATIONAL GUIDE
Each meter is supplied with batteries. Before using the meter for the first time, open the battery compartment and insert batteries, observing the polarity (see “Battery Replacement“).
CONNECTING THE ELECTRODE
With the meter turned off, connect the FC2153 probe to the DIN socket on the bottom of the meter by aligning the pins and pushing in the plug firmly. Remove the protective cap from the probe before taking any measurements.
TURNING THE METER ON
To turn the meter ON, press the button on the front of the meter. If it does not turn on, make sure that the batteries are properly installed in their place. The meter is provided with an active acoustic signal when a key is pressed. At  start‑up the meter displays all LCD segments for a few seconds, followed by the percentage indication of the remaining battery life, displaying “WAIT“ until electrode check is in process then the meter enters the normal measurement mode.

Note: The meter detects the presence and the type of the probe at its input.

• If the probe is not connected the message “NO” ”PROBE“ appears alternatively on the secondary LCD with “—“ blinking on the first LCD line.
• If the probe is not compatible “WRONG” ”PROBE“ message appears alternatively on the secondary LCD with “—“ blinking on the first LCD line.
• If the readings are out of range, the nearest range limits are displayed blinking (e.g. -2.00 pH -5.0 °C).

SELECTING MEASUREMENT RANGE
While in measurement mode, press the SET button to select pH or pH‑mV measurement on the first LCD line.
FREEZING MEASUREMENT VALUES
While in measurement mode, press and hold the SET button until “HOLD“ appears on the secondary LCD. The
“HOLD“ remains for 1 second and reading of pH, mV and temperature will be frozen on the LCD with “H” blinking.

Press any button to resume active measurements.
ENTERING CALIBRATION MODE
Press and hold the button until ”POWER” and tag is replaced by “STD“ and tag. Release the button.
ENTERING SETUP MODE
Press and hold button until “STD“ and tag is replaced by “SETUP“ and tag. Release the button.
TURNING THE METER OFF
While in measurement mode, press the button.
”POWER” and tag will appear. Release the button.

pH MEASUREMENT & CALIBRATION
Make sure the meter has been calibrated before use.
If the probe is dry, soak it in HI70300 storage solution for 30 minutes to reactivate it. If soiled, clean the electrode by soaking in cleaning solution for 20 minutes, then rinse the tip and soak in storage solution at least 30 minutes before  use.
Rinse the electrode off well and shake off excess droplets.
Recalibrate before using.
Submerge the probe in the sample to be tested while stirring it gently.
Wait until the tag on the LCD disappears.

The LCD displays the pH value (automatically compensated for temperature) on the primary LCD, while the secondary
LCD displays the sample temperature.
If measurements are taken in different samples successively, rinse the probe tip thoroughly in distilled or deionized water to eliminate cross‑contamination.
For better accuracy, frequent calibration of the pH sensor with the meter is recommended. In addition, the meter must be recalibrated:
a) whenever the pH electrode is replaced.
b) after testing aggressive chemicals.
c) when high accuracy is required.
d) at least once a month.
e) after cleaning the sensor.

pH calibration
Enter calibration mode while in pH measurement mode. Place the sensor into the first calibration buffer. If performing a two‑point calibration, use pH 7.01 (pH 6.86 for NIST) buffer first. The meter will enter the calibration mode, displaying “pH 7.01 USE” and tag blinking (or “pH 6.86 USE” for NIST).
Follow directions for single and two‑point calibration below:

Single-point calibration

1. Place the probe in any buffer from the selected buffer set.
   The meter will automatically recognize the buffer value.

2. If the buffer is not recognized or the calibration offset is out of the accepted range “—- WRONG“ is displayed.

3. If the buffer is recognized “REC“ is displayed then “WAIT“ until the calibration is accepted.
   If using pH 7.01 (or pH 6.86 for NIST), after acceptance of the buffer press any key to exit. The ”SAVE” message is displayed and the meter returns to pH measurement mode.
   If using pH 4.01 or 10.01 (or pH 9.18 for NIST) buffer the ”SAVE” message is displayed and the meter returns to pH measurement mode.

Two-point calibration
Proceed with steps 1 through 3 under single‑point calibration using 7.01 pH (pH 6.86 for NIST) buffer first.
Then follow steps below:
The ”pH 4.01 USE” message is then displayed.
Place the probe in the second calibration buffer (pH 4.01 or 10.01, or, if using NIST, pH 4.01 or 9.18). When the second buffer is accepted, the LCD will display “SAVE” for 1 second and the meter will return to the normal
measurement mode.
If the buffer is not recognized or the slope is out of accepted range ”— WRONG” is displayed. Change the buffer, clean the electrode or press any key to exit calibration.
For better accuracy it is always recommended to carry out a two‑point calibration.
After the calibration procedure has been completed, the tag is turned on together with the calibrated points.

Exiting calibration and resetting default values
After entering the calibration mode and before the first point is accepted, it is possible to quit the procedure and return to the last calibration data by pressing the button. The LCD displays “ESC“ for 1 second and the meter returns to normal mode.
To reset the default values and clear a previous calibration, press the SET button after entering the calibration mode and before the first point is accepted.
The LCD displays “CLEAR“ for 1 second, the meter resets to the default calibration and the tag with the calibrated points on the LCD disappears.

ELECTRODE CONDITION
The display is provided with a probe icon (unless the feature is disabled from setup) which indicates the electrode status after calibration. The “condition” remains active for 12 hours (unless the batteries are removed).
The electrode condition is evaluated only if the current calibration has two points.
5 bars: excellent condition
4 bars: very good condition
3 bars: good condition
2 bars: fair condition
1 bar: poor condition
1 bar blinking: very poor condition
With 1 bar it is recommended to clean the electrode and recalibrate. If there is still only 1 bar or 1 bar blinking replace the probe.

Sensor check
Setting the meter to pH‑mV range the user can check the sensor status at any time. The offset value is the reading in pH 7.01 buffer (@ 25 °C/77 °F). If this reading is outside the range ±30 mV, the electrode is considered “very poor”. The  slope value of the sensor is the difference between readings in pH 7.01 and in pH 4.01 buffers. When the slope reaches the value of about 150 mV, the electrode is considered “very poor“. When “poor“ or “very poor“, it is recommended to  replace it with a new one.
Note: To ensure reliable readings, the electrode must be cleaned with cleaning solution and then hydrated in storage solution for a minimum of 30 minutes before calibrating the probe.

METER SETUP

Setup mode allows the selection of the Temperature unit, Auto‑off, Beep confirmation tone, the type of pH buffer set, the Resolution and Information. To enter Setup mode press and hold button until “STD“ and tag is replaced by  “SETUP“ and tag. Release the button.

• “TEMP“ is displayed on the secondary LCD with the current temperature unit (e.g. “TEMP °C“),for °C/°F selection, use the SET button. After the temperature unit has been selected, press to confirm and to enter the “A-OFF“  selection.
  

• Use the SET button, to navigate through the auto‑off choices: 8 minutes (“8”, default value), 60 minutes (“60”) or disabled (“—”). Press to confirm and to enter the “BEEP“ selection.

• To switch the beep tone ON or OFF, press the SET button; press to confirm and to enter the calibration buffer selection “pH 7.01 BUFF“.

• To change the buffer set, the meter will show the current buffer set: “pH 7.01 BUFF” (for standard buffer set: 4.01/7.01/10.01) or “pH 6.86 BUFF” (for NIST buffer set: 4.01/6.86/9.18). Change the set with the SET button. Press to  confirm and to enter pH resolution selection “RESOL“.

• To change the pH measurement resolution between “0.1“ and “0.01“ use the SET button; then press to confirm and to enter electrode calibration information “INFO“ selection.

• To switch the electrode condition indicator on the LCD ON or OFF, press the SET button; press to exit setup options. Change the set with the SET button, then press to confirm and to return to normal mode.

BATTERY REPLACEMENT

When the remaining battery life is less than 10% the battery tag blinks on the display to warn the user.
