[. . . ] Instruction Manual HI 98140 HI 98150 HI 98160 Calibration Check pH/mV/Temperature Meters w w w. c o m 1 Dear Customer, Thank you for choosing a Hanna Instruments product. Please read this instruction manual carefully before using the instruments. This manual will provide you with the necessary information for correct use of the instruments, as well as a precise idea of their versatility. [. . . ] Notes: · When the instrument is not calibrated or calibration is cleared (default values loaded) there is no "expired calibration", and the display always shows the "Cal Due" tag blinking. · When an abnormal condition in the RTC is detected, the instrument forces the "expired calibration" status. LAST pH CALIBRATION DATA The last pH calibration data is stored automatically after a successful calibration. To view the pH calibration data, press 2nd then GLP when the instrument is in pH measurement mode. The instrument will display the date (mm. dd) and the time (hh:mm) of the last calibration. The "condition" bargraph remains active until the end of the calibration day. 18 Press the ARROW keys to view the next calibration parameter (pressing the key): · The pH calibration slope and offset. The GLP slope is the average of the calibration slopes; the percentage is referred to the ideal slope value. · The calibration buffers in calibrating order, for the last calibration. The first pH calibration buffer: The second pH calibration buffer (if exist): The third pH calibration buffer (if exist): The fourth pH calibration buffer (if exist): The fifth pH calibration buffer (if exist): 19 Notes: · The "OLd" message displayed beside the pH value means that this buffer was not used during last calibration. Press 2nd then Setup if you want to see calibration date (or time, if old calibration was performed in the same day with current calibration). In this case, the calibration buffer number is not displayed on the LCD. · If "not CAL" message appears on the LCD, the instrument informs you that calibration was performed in less than five points. If disabled, or the number of days until the calibration alarm will be displayed (e. g. · The instrument ID. LAST RELATIVE mV CALIBRATION DATA Last Relative mV calibration data is stored automatically after a successful calibration. To view the Relative mV calibration data, press 2nd then GLP while in Relative mV measurement mode. · The date (mm. dd) and the time (hh:mm:ss) of the last Rel mV calibration as in pH GLP mode. Press the ARROW keys to view the next calibration parameter (pressing the key): · The Relative mV calibration offset as in pH GLP mode. Notes: · Press 2nd then GLP or only GLP at any moment and the instrument will return to measurement mode. · If calibration has not been performed, the instrument displays "no CAL" message blinking. · Press 2nd and Setup while date and time are displayed in order to view the year in the first LCD line. 20 SETUP Setup mode allows viewing and configuring the following parameters: · Calibration Alarm Time Out (pH range only)(dAY) · Custom buffers (1 or 2) (pH range only) (Custom) · One-point calibration behavior (pH range only) (1Pnt) · Current Time (hour & minute) · Current Date (month, day & year) · Beep Status (bEEP) · Instrument ID (InSld) · Auto-off backlight timer (LIGH) · Auto power off timer (AOFF) · Temperature Unit To enter SETUP mode, press Setup button directly on the HI 98140 and 2nd then Setup on the HI 98150 & HI 98160 while the instrument is in measurement mode. minutes), press Range (HI 98150 & HI 98160), 2nd then Mode (HI 98140).
