Dear Customer, Thank you for choosing a Hanna Product. Please read this instruction manual carefully before using the instrument. This manual will provide you with the necessary information for the correct use of the instrument, as well as a precise idea of its versatility. If you need more technical information, do not hesitate to e-mail us at tech@hannainst.com. These instruments are in compliance with directives EN 50081-1 and 50082-1. TABLE OF CONTENTS PRELIMINARY EXAMINATION ..........................
For special applications, HI 70606/2 or HI 70606/5 RH probes can also be used. These probes come with a sintered cap on the sensor shaft for protection in dusty or corrosive environments. An independent temperature probe provides highly accurate temperature readings. While in logging mode, HI 91610 stores the measurements into memory at a user selected interval from 1 to 180 minutes. The data can be retrieved at a later date for printing or can be transferred to a computer through the HI 9200 transmitter.

INITIAL PREPARATION OPERATIONAL GUIDE Each meter is supplied complete with 4 x 1.5V common AA batteries. Unscrew and remove the back cover, unwrap the batteries and install them while paying attention to their polarity. Connect the RH probe to the 7-pin DIN socket on the top of the meter and fasten the threaded ring tightly. Connect the temperature probe to the appropriate connector.
If neither a temperature probe nor a calibration test plug is connected, the meter will display on the primary display and print "----" to alert the user. This could also indicate that the probe cable is damaged. Hanna offers a wide range of temperature probes to meet all temperature measurement requirements. Hanna probes use highly sensitive thermistor sensors which provide greater accuracy and faster response than conventional thermistor probes.
To select the hour, press the UP or the DOWN keys (24 hour clock). UP When the correct year is selected, press the TIME key once more to memorize it. The month will start blinking. DOWN To memorize the hour press RANGE once again. The minutes will start blinking. TIME Select the month by using the UP or the DOWN keys. RANGE UP Likewise, use UP and DOWN to set the minutes. UP DOWN Press TIME. The day will start blinking.
To view temperature on the primary display with decimal points press the RANGE key. To select the hour, press the UP or DOWN keys (24 hour clock). UP DOWN °C To set the hour press the TIME key again and the minutes will blink. RANGE If “----" is displayed, it indicates that no probe is connected (or probe cable is broken). TIME Use the UP or DOWN keys to select the correct minutes. UP DOWN Press the ALT and the TIME keys together to exit this mode and memorize the minute setting.
To view RH% on the primary display press RANGE. meter will print the measurements taken in that moment, and will print with the indicated printing interval thereafter until the ON/OFF key is pressed. The printout provides the following information: a – A running log number b – A running sample number in that particular log c – Date (DD-MM-YY) d – Printing interval in minutes e – Time (HH.
TO STOP RECORDING To exit the recording mode, press the ON/OFF key. The instrument will then make one final exit printout. <> 10-01-96 --01 -- 0005M 0006 *12.01 ALT UP DOWN RANGE TIME LOG Press the ALT and PAPER keys at the same time and the "LOG" symbol on display will start to blink. 65.1 RH% 25.0 °C ON/OFF The running log number can be reset by simply removing the batteries.
Press the ALT and LOG key simultaneously to enter the logging mode. The current log number and the remaining page numbers will appear for a few seconds on the display to indicate the correct operational mode. The printer will print a complete set of data and the "LOG" symbol will appear on the secondary LCD. ALT UP DOWN RANGE TIME LOG LOG If no key is pressed, the display goes blank after about 5 minutes and comes back on only to print at the next logging interval.
While pressing the ALT key, press the DOWN key until the log number to scan appears on the secondary display. The primary display will show the number of samples in that particular log. To exit from the recall mode press the LOG key. LOG Note: this mode will not alter data already present in the memory. ALT TO PRINT STORED DATA DOWN Press the ALT and the RANGE keys simultaneously. This now shows the date when logging started.
CALIBRATION 2 O Li Cl 11.1% Na Cl 75.4% Li Cl 11.1% CALIBRATION KIT H All Hanna thermohygrometers have been precalibrated at the factory. Hanna Instruments uses state-of-the-art thermally-isolated humidity chambers for this purpose. It is generally recommended to have all thermohygrometers recalibrated at least once a year. For an accurate annual recalibration, contact your dealer or the nearest Hanna Customer Service Center.
• Press the ON/OFF key (for HI 9161/ HI 9261) or the RANGE key (for HI 91610) to switch the instrument on. • Leaving the probe in the "RH 75.4%" chamber, adjust the low humidity trimmer until the display shows 75.4%. ON/OFF • Press the RANGE key to display the RH% reading on the primary LCD. RANGE • Turn the low humidity trimmer (see Functional Description) until a value of 0.0% is reached (readings between 0.0% and 1.0% RH are acceptable). • The humidity calibration is now complete.
HI 92000 allows use of commonest spread sheet programs (e.g. Excel, Lotus 1-2-3) and offers a variety of features with an on-line help routine. To install HI 92000, you need a 3.5" drive and a couple of minutes to follow the short instructions conveniently printed on the disk label. SELF-DIAGNOSTIC FUNCTIONS HI 9161, HI 9261 and HI 91610 are factory programmed to automatically diagnose a fault and inform the user by displaying an error code on the LCD.
Allow about 5 cm (2") of paper to exit from the printer and then replace the cover. TO RESET THE PRINTER Take the battery cover off by removing the screws on the back of the meter. Using a blunt pencil press the black reset button. This will reset the printing mechanism. Before replacing the battery cover, investigate likely cause of the printer jam (e.g. the paper might be caught under the cover preventing the paper from advancing). Replace the battery cover and tighten the screws. - 1.5V + 1.
ACCESSORIES R.H. PROBES Hanna Instruments Relative Humidity probes use a high-tech ThinFilm Polymer Capacitance humidity sensor. This sensor provides rapid response and high accuracy. The probes are precalibrated and as a result are all interchangeable. Several different versions are available for your specific R.H. needs. HI 70604/5 R.H. probe with 5 m (16.5') cable HI 70606/2 R.H. probe with sintered protective cap and 2 m (7') cable HI 70606/5 R.H. probe with sintered cap and 5 m (16.
CALIBRATION TEST PLUGS Hanna Test Plugs provide a quick and easy way to test the meter's accuracy by simply connecting these Test Plugs to the probe connector of the meter. If the reading differs by more than ±0.4°C (±0.8°F) from the Test Plug value, the unit is due for recalibration. Choose the right Test Plug to suit your needs: HI 762-18C Calibration key, -18.0°C ±0.4°C HI 762000C Calibration key, 0.0°C ±0.4°C HI 762070C Calibration key, +70.0°C ±0.4°C HI 762-004F Calibration key, -0.4°F ±0.
