GENERAL DESCRIPTION
SPECIFICATIONS
PRELIMINARY EXAMINATION
ACCESSORIES
•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 condary display, and an audible signal is produced.
If a single-point calibration with buffers pH 7.01 or 6.86 is desired, then after recognition of the buffer
press any key to return to the pH measurement mode.
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 nsor into the cond calibration buffer. The message is held for 12 conds,unless a valid buffer is recognized. If no valid buffer is recognized,then the “---WRONG“ 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 ac-cepted, the LCD displays the accepted value with the “OK 2”message on the condary 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 ret default values
职业规划书模板•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 condary LCD displays “---ESC“ for 1 cond and the meter returns to normal mode.
•To ret 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 condary LCD displays “---CLR“ for 1 cond, the meter rets to the default calibration and the “Calibrated” tag on the LCD disappears.
First time you u the instrument open the battery compartment and put the batteries inside obrving the polarity.To connect the probe
With the meter turned off, connect the HI 1414D/50 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 gments are di
splayed for 1 cond, then the percent indication of the remaining battery life is displayed for another cond (E.g. “100 % BATT“). The meter then enters the normal measuring mode.
Note :If the display needs to be checked, keep the ON button
presd while turning the meter on. The meter will display all gments as long as the button is presd.To freeze the display
While in measurement mode, press the SET/HOLD button, “HOLD“appears on the condary 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 condary display. Relea the button.
The meter is provided with an acoustic signal active when a key is presd.
荷花怎么种Notes :•When the meter detects the abnce 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 condary LCD displays “25.0°C “ (“77°F“) blinking. When the probe is reconnected,the “Probe not connected“ tag is turned off, the temperature is displayed on the condary display and the “ATC“ tag is turned on.
•To clean the meter, do not u aggressive detergents.It is recommended to u water.
•Make sure the meter has been calibrated before u.
•If the probe is dry, soak it in HI 70300 storage solution for 30 minutes to reactivate it.
•For better result, before taking any measurement, wet the skin portion to be tested with distilled water or HI 70960 electrolyte solution.
•Place the flat tip of the probe that is wetted with the electrolyte solution on the sample to be tested and 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 condary LCD displays the temperature of the sample.
•After each measurement, it is recommended to clean the probe tip with HI 70620 and HI 70621 Cleaning & disinfecting solutions , to eliminate coatings and avoid cross-contamination.•When not in u, switch the meter OFF and clean the probe with HI 70620 and HI 70621 Cleaning & disinfecting solutions before storing it.pH calibration
For better accuracy, frequent calibration of the pH nsor with the meter is recommended. In addition, the meter must be recalibrated:
a)Before each t of skin measurements.
b)Whenever the pH electrode is replaced or stored for long periods.
c)Where high accuracy is required.
•From normal mode, press and hold the ON/OFF/MODE button until “OFF“ on the condary display is replaced by “CAL“.Relea the button. Place the nsor into the first calibration buffer.•The meter enters the calibration mode, displaying “pH 7.01USE” (or “pH 6.86 USE” if the NIST buffer t was lected).After 1 cond 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 co
ndary LCD. If no valid buffer is detected, the meter keeps the “USE“indication active for 12 conds, and then replaces it with “---WRONG“, indicating that the sample being measured is not a valid buffer.
Setup mode allows the lection of the temperature unit and the type of pH buffer t.
To enter the Setup mode, press and hold the ON/OFF/MODE button until “CAL“ on the condary display is replaced by “TEMP“and the current temperature unit (E.g. “TEMP °C“). Then:•for °C/°F lection , u the SET/HOLD button. After the temperature unit has been lected, press ON/OFF/MODE to enter the buffer t lection mode; press ON/OFF/MODE twice to return to the normal measuring mode.
•to change the type of calibration buffer t , after tting the temperature unit, the meter will show the current buffer t:“pH 7.01 BUFF” (for standard buffer t: 4.01/7.01/10.01) or “pH 6.86 BUFF” (for NIST buffer t: 4.01/6.86/9.18). Change the t 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 cau 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 obrving the polarity on the rear of the instrument.
•Clo the battery compartment cap.
