GENERAL DESCRIPTION HI 9141 and HI 91410 are portable, printing DO meters designed for continuous monitoring and recording at selectable time intervals. The low-power printer uses regular paper that is easily sourced and will not fade over time. HI 91410 combines all of the comprehensive printing functions of the HI 9141, with the capability to log measurements. In addition to supplying the user with instant print-outs of DO, HI 91410 also provides datalogging facilities that will store up to 8000 readings.

INITIAL PROBE PREPARATION All HANNA DO probes are shipped dry. To hydrate the probe and prepare it for use, connect it to the meter and proceed as follows: Shipping 1. Remove the red & black plascap tic cap. This cap is for shipping purposes and can be thrown away. black 2. Wet the sensor by soaking the bottom 2.5 cm (1") of the red probe in HI 7041S electrolyte solution for 5 minutes. 3. Rinse the membrane (HI76407A supplied with the meter) with electrolyte solution while shaking it gently.
• • • For an accurate calibration, it is recommended to wait for 5-10 minutes to ensure precise conditioning of the probe. Remove the protective cap. Press the CAL key. The "CAL" message is displayed to indicate that the calibration mode has been entered.
taking into account the lower degree of oxygen solubility in such conditions (see "Altitude Compensation" and "Salinity Compensation" sections for details). Remember to set altitude and/or salinity before taking ppm measurements, and the meter will automatically compensate for these factors. TEMPERATURE READINGS The supplied probe is provided with a built-in temperature sensor. Press the FUNCTION key to display the measured temperature.
Set the month with the UP or DOWN keys. DOWN To select the hour, press the UP or DOWN keys (24 hour clock). UP DOWN Press CAL, and the day will start blinking. UP Press CAL and the minutes will start blinking. DATE CAL TIME INTV Use the UP or DOWN keys to set the day. CAL Use UP or DOWN keys to set the minutes. DOWN UP Press CAL to confirm the selected date, then FUNCTION to leave the date setting mode. DOWN UP Press the CAL key to confirm the selected time and printing interval.
abcdef g- PRINTING / RECORDING WITH HI 9141 To print the measured values, press the PRINT key. PRINT <> The printout provides the following information: a - Current sample number b - Date (DD-MM-YY) c - Time (HH-MM) 14-01-96 d - D.O. value in 0015 *00.50 ppm. 8.1 ppm e - Temperature 20.4 °C value in °C. RECORDING MODE (PROGRAMMED PRINTOUTS ) Press the RECORD key to enter the recording mode.
<> To print the measured values shown on display, press the PRINT key. PRINT This function can be activated in normal operation mode as well as during logging. When in measurement mode, the printout provides the following information: a - Current sample number b - Date (DD-MM-YY) c - Time (HH-MM) d - DO value in ppm 14-01-96 e - Temperature value 0001 *16.50 8.95 ppm in °C 20.
The printer will print a complete set of data and the "LOG" symbol is displayed. <> Each printout provides the following information: a - Current log number b - Current sample number (in that log) c - Date (DD-MM-YY) d - Printing interval indicator in minutes e - Time (HH-MM) f - DO value in ppm 14-01-96 g - Temperature --03-0010M value in °C 0001 *19.10 8.02 ppm 22.1 °C • • a b c d e f Once in logging mode, the interval cannot be changed.
ALTITUDE COMPENSATION SALINITY COMPENSATION Press the FUNCTION key twice and “F1” will be displayed. Press FUNCTION key until “F2” is displayed. FUNCTION FUNCTION Use the UP and DOWN keys to set the altitude between 1 and 1900 m, in steps of 100 m (1 meter = 3.28 feet). Use the UP and DOWN keys to set the salinity between 0 and 40 g/L. DOWN DOWN Salinity affects the dissolved oxygen concentration by decreasing its value.
PROBE & MEMBRANE MAINTENANCE • • The DO probe body is made of reinforced plastic for maximum durability. A built-in thermistor temperature sensor provides temperature measurements. It is always recommended to keep the protective cap on the probe when it is not used, to provide protection against damage and dirt. To replace the membrane or refill with electrolyte, proceed as follows: • • • • • Remove the protective cap by gently twisting and pulling it off the probe body (fig.1).
DATA TRANSFER TO PC (HI 91410) Press the FUNCTION key until "F2" is displayed on the secondary LCD. FUNCTION Place the instrument on the HI 9200 infrared transmitter (ensuring that the infrared LEDs of meter and interface match). The memory can be downloaded to your PC through a serial port. During the data transfer the instrument displays the "r 232" message. Data transmission from the instrument to the PC is handled with the HI 92000 Windows® compatible software by HANNA instruments®.
MEMORY ORGANIZATION (HI 91410 ONLY) Capacity: 8000 data samples, divided into 16 pages. Data capacity per page: 500 data samples. Each time a new logging period starts, it automatically starts from a new page. If “LOGGING” is still on, and the available page is “0” the meter will overwrite the first LOT DATA in the existing meter memory. During logging the meter automatically returns to the oldest page in the memory and if it contains data, it will overwrite it.
BATTERY REPLACEMENT When batteries become °C weak, the "LO BAT" indicaLO BAT tion is displayed to warn the user. If it blinks during printing, it means that 200 printouts can be made before the batteries are exhausted. When there is only sufficient power for 100 printouts, the "LO BAT" indication is displayed continuously. TO RESET THE PRINTER Battery replacement must only take place in a safe area and using the battery type specified in this instruction manual.
HI9141 and HI91410 can also be used with other adapters. In this case, remember to check the correct polarity of your adapter before connecting it to the meter. WARNING: In HI91410, if the external power supply and batteries are disconnected, all stored data will be erased. Always apply external power supply to the instrument before replacing the batteries, to prevent data from being lost.
