WARRANTY

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 HI 1288 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 select the measurement range
While in normal measurement mode, press the SET/HOLD button
quickly to select pH, EC or TDS value on the primary LCD, while
temperature will be simultaneously displayed on the secondary
LCD (E.g. “pH 5.73“ and “22.5°C“).
To freeze the display
While in measurement mode, press and hold the SET/HOLD
button until “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.
Note:When the meter detects the absence of probe at its input,
the message “Probe not connected“ appears on LCD and ''-
--'' blinking on LCD lines. When a probe is connected, the
“Probe not connected“ tag is turned off, and the readings
are displayed on LCD lines.
While in measurement mode, press and hold the ON/OFF/MODE
button until “TEMP” and the current temperature unit are
displayed on the lower LCD (eg. “TEMP °C“). Then:
To select the temperature unit (°C / °F)
• Press the SET/HOLD button to change the temperature unit,
and then press the ON/OFF/MODE button until the meter
returns to normal measurement mode.
To change the type of calibration buffer set ,
•While in pH measurement mode, after setting the temperature
unit press the ON/OFF/MODE button again to 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.
To change the EC/TDS conversion factor (CONV) and the
temperature compensation coefficient (BETA)
•While in EC or TDS measurement mode after setting the
temperature unit press the ON/OFF/MODE button again to
show the current conversion factor (eg. “0.50 CONV“), then
press SET/HOLD to change the value.
•Press the ON/OFF/MODE button to show the current temperature
compensation coefficient b (eg. “2.1 BETA“), then press
SET/HOLD to change the temperature coefficient value.
•Press the ON/OFF/MODE button to return to normal opera-
tion.
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.
•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.
•Submerge the probe in the sample to be tested while stirring it
gently. Wait until the “Not Stable“ tag on the LCD is turned off.
•The pH value automatically compensated for temperature is
displayed 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 to eliminate cross-contamination.
After cleaning, rinse the probe tip with some deionized water
and some of the sample to be measured.
pH calibration
•While in pH measurement 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).
•For a single-point calibration place the probe in any buffer from
the selected buffer set (E.g. pH 4.01, 9.18 or 10.01). The meter
will automatically recognize the buffer value.
•If the buffer is not recognized or the calibration offset is out of
the accepted range ''---WRONG'' is displayed.
•If the buffer is recognised ''REC" is displayed until the reading is
stable and the calibration is accepted.
•If using pH 7.01 (or pH 6.86 from NIST buffer set), after
acceptance of the buffer press any key to exit. ''OK1'' message is
displayed and meter returns to pH measurment mode.
•If using 4.01 or 10.01 (9.18) buffer the ''OK1'' message is
displayed and meter returns to pH measurment mode.
•For a two-point calibration , proceed as for the single point
calibration selecting 7.01/6.86 pH buffer.
•The ''pH 4.01 USE'' message is 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 “OK2” for 1 second and
the meter will return to the normal measurement mode.
•If the buffer is not recognised or the slope is out of accepted
range ''---WRONG'' is displayed. Change the buffer, clean the
electrode or press any key to exit calibration.
•When the calibration procedure is completed, the “Calibrated“
tag is turned on.
•It is always recommended to carry out a two-point calibration for
better accuracy.
OPERATIONAL GUIDE pH MEASUREMENT & CALIBRATION
•Place the probe in the sample to be tested. Use plastic beakers
or containers to minimize any electromagnetic interference.
•Tap the probe lightly on the bottom of the container to remove
air bubbles that may be trapped inside the tip.
•Wait for a few minutes for the temperature sensor to reach
thermal equilibrium (i.e. until the “Not Stable“ tag disappears).
•The LCD displays the EC or TDS value (automatically compen-
sated for temperature) on the primary LCD, while the secondary
LCD displays the temperature of the solution.
EC calibration
•From EC or TDS normal mode, press and hold the ON/OFF/
MODE button until “OFF“ on the secondary display is replaced
by “CAL“. Release the button.
•The meter enters the calibration mode. Immerse the probe in
the HI 7031 calibration solution (“µS 1413 USE“) for
HI 991300 or in HI 7030 calibration solution (“mS 12.88
USE“) for HI 991301.
•If the standard value is recognised ''REC'' is displayed until the
reading is stable and calibration is accepted.
•The LCD will display “OK” for 1 second and return to normal
measurement mode.
•If the standard is not recognised or the slope is out of accepted
range ''---Wrong'' is display. Change the calibration solution
or the electrode or press any key to exit calibration.
•When the calibration procedure is completed, the “Calibrated“
tag is turned on.
Notes:•Beta should be set to 1.9 during calibration.
•Since there is a known relationship between the EC
and TDS reading, it is not necessary to calibrate the
meter in TDS. If the conversion factor is either 0.5 or
0.7, the meter will allow a direct calibration in TDS
by using the Hanna calibration solutions.
To exit calibration and reset default values
•After entering the calibration mode and before the 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 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/HOLD button after entering the calibration
mode, before the first point is accepted.
The LCD displays “---CLR“ for 1 second, the meter resets to the
default calibration and the “Calibrated” tag on the LCD disap-
pears.
