Instruction Manual
HI 99191
Portable Waterproof pH / Temperature
Meter for Drinking Water Analysis

If a single-point calibration with buffers pH 7.01 or 6.86 is
desired, after recognition of the buffer press any key to return
to the pH measurement mode. After the button is pressed, the
meter displays “7.01“(or “6.86“) - “OK 1“, and an audible
signal is produced.
Note:It is always recommended to carry out a two-point calibration
for better accuracy.
•For a
two-point calibration
, place the probe in pH 7.01 (or pH
6.86) buffer first. After the calibration point has been accepted,
the “pH 4.01 USE” message appears. Place the sensor into the
second calibration buffer. The message is held for 12 seconds,
unless a valid buffer is recognized. If no valid buffer is
recognized, then the ''---WRNG'' message is displayed. If a
valid buffer (pH 4.01, pH 10.01 or pH 9.18) is detected,
then the meter completes the calibration procedure. When
the buffer is accepted, the LCD displays the accepted value
with the “OK 2” message on the secondary display. The meter
then returns to the normal measuring mode.
Note:When the calibration procedure is completed, the
“Calibrated“ tag is turned on.
To exit calibration and to reset to the 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 ON/OFF/MODE button.
The secondary LCD displays “---ESC“ for 1 second and the
meter returns to normal mode.
•To reset to the default values and clear a previous calibration,
press the SET/HOLD button after entering the calibration
mode and before the first point is accepted.
The secondary LCD displays “---CLR“ for 1 second, the meter
resets to the default calibration and the “Calibrated” tag on
the LCD disappears.
First time you use the instrument open the battery compartment
and put the batteries inside observing the polarity.
To connect the probe
With the meter turned off, connect the FC 215D probe to the DIN
socket on the bottom of the meter by aligning the pins and
pushing in the plug. Tighten the nut to ensure a good connection.
Remove the protective cap from the probe before taking any
measurements.
To turn the meter ON and check the battery status
Press the ON/OFF/MODE button until the display lights up. At
start-up, all the LCD segments are displayed for 1 second, then
the percent indication of the remaining battery life is displayed for
another second (E.g. “100 % BATT“). The meter then enters the
normal measuring mode.
Note:If the display needs to be checked, keep the ON button
pressed while turning the meter on. The meter will display
all segments as long as the button is pressed.
To freeze the display
While in measurement mode, press the SET/HOLD button, “HOLD“
appears on the secondary display and the reading will be frozen
on the LCD (E.g. “pH 5.73 HOLD“). Press any button to return to
normal mode.
To turn the meter OFF
While in normal measurement mode, press the ON/OFF/MODE
button. “OFF“ will appear on the secondary display. Release the
button.
The meter is provided with an acoustic signal active when a key is
pressed.
Note:When the meter detects the absence of a temperature probe
at its input, the message “Probe not connected“ appears
on LCD and the Automatic Temperature Compensation is
turned off along with the “ATC“ tag. In this condition, the
secondary LCD displays “---- °C “ (“---- °F“) blinking.
When the probe is reconnected, the “Probe not connected“
tag is turned off, the temperature is displayed on the
secondary display and the “ATC“ tag is turned on.
Setup mode allows the selection of the temperature unit and the
type of pH buffer set.
To enter the Setup mode, press and hold the ON/OFF/MODE
button until “CAL“ on the secondary display is replaced by “TEMP“
and the current temperature unit (E.g. “TEMP °C“). Then:
•
for °C/°F selection
, use the SET/HOLD button. After the
temperature unit has been selected, press ON/OFF/MODE to
enter the buffer set selection mode; press ON/OFF/MODE
twice to return to the normal measuring mode.
•
to change the type of calibration buffer set
, after setting the
temperature unit, 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/HOLD button, then press ON/OFF/
MODE to return to normal mode.
The meter is supplied with batteries.
The meter displays the remaining battery percentage when turned
on. When the level is below 5%, the “
- +
“ symbol on the LCD
blinks to indicate a low battery condition. If the battery level is low
enough to cause erroneous readings, the Battery Error Prevention
System (BEPS) turns the meter off. It is recommended to replace
the batteries as soon as the display will flash the battery symbol.
To replace the batteries, follow the next steps:
•Open the battery compartment cap (on the bottom of the
instrument).
•Remove old batteries.
•Replace new batteries observing the polarity on the rear of
the instrument.
•Close the battery compartment cap.
BATTERY REPLACEMENT
OPERATIONAL GUIDE pH MEASUREMENT & CALIBRATION METER SETUP
•Make sure the meter has been calibrated before use.
•If the probe is dry, soak it in HI 70300 storage solution for
30 minutes to reactivate it.
•Place the tip of the probe into the sample to be tested.
•Wait until the “Not Stable“ tag on the LCD is turned off.
•The LCD displays the pH value (automatically compensated for
temperature) on the primary LCD, while the secondary LCD
displays the temperature of the solution.
•If measurements are taken in different samples successively,
rinse the probe tip thoroughly to eliminate cross-contamination.
For cleaning procedure choose the suitable Hanna cleaning
solutions (see Accessories section).
After cleaning, rinse the probe tip with some deionized water
and some of the sample to be measured.
pH calibration
For better accuracy, frequent calibration of the pH sensor with
the meter is recommended. In addition, the meter must be
recalibrated whenever:
a) The pH electrode is replaced.
b) After testing aggressive chemicals.
c) Where high accuracy is required.
d) At least once a month.
•From normal mode, press and hold the ON/OFF/MODE button
until “OFF“ on the secondary display is replaced by “CAL“.
Release the button. Place the sensor into the first calibration buffer.
•The meter enters the calibration mode, displaying “pH 7.01
USE” (or “pH 6.86 USE” if the NIST buffer set was selected).
After 1 second the meter activates the automatic buffer recognition
feature. If a valid buffer is detected, then its value is displayed
on the primary display, and “REC“ appears on the secondary
LCD. If no valid buffer is detected, the meter keeps the “USE“
indication active for 12 seconds, and then replaces it with
“---WRNG“, indicating that the sample being measured is not
a valid buffer.
•For a
single-point calibration
with buffers pH 4.01, 9.18 or
10.01, the meter automatically accepts the calibration when
the reading is stable; the meter will show on the primary display
the accepted buffer, with the message “OK 1” on the secondary
display, and an audible signal is produced.
