Dear Customer, Thank you for choosing a HANNA instruments ® product. All Hanna Instruments meters are warranted for two years Please read this instruction manual carefully before using the instru- against defects in workmanship and materials when used for their ment.
GENERAL DESCRIPTION FUNCTIONAL DESCRIPTION HI 9161 HI 9161 and HI 91610 are advanced portable, printing, thermo- hygrometers. These unique, lightweight meters give instant printouts of sample number, date and time of recording, printing interval, relative humidity and temperature at user-selectable intervals. Both RH and temperature are measured with 0.1 resolution.

All HANNA thermo-hygrometers have been precalibrated at the ® factory. HANNA instruments uses state-of-the-art thermally-isolated • Pour approximately 12 cc of distilled wa- humidity chambers for this purpose.
• Adjust the low humidity trimmer to read 0.0% (readings between DATA TRANSFER TO PC 0.0 and 1.0% RH are acceptable). (HI 91610 only) Set the HI 91610 to TIME mode and place it on a HI 9200 infrared transmitter (ensuring that the infrared LEDs of meter and interface TIME match).
BATTERY REPLACEMENT SELF-DIAGNOSTIC FUNCTIONS HI 9161 and HI 91610 are factory programmed to automatically When the batteries become weak, diagnose a fault and inform the user by displaying an error code on the "LO BAT" indication is displayed the LCD. to warn the user.
Allow about 5 cm (2") of paper to exit from the printer and then PRINTER MAINTENANCE replace the cover. CHANGING THE INK CARTRIDGE When printouts become faint, it might be necessary to change the ink cartridge. Contact your dealer or the nearest HANNA Office for technical service.
HANNA INSTRUMENTS TEMPERATURE PROBES ACCESSORIES RH PROBES HANNA Relative Humidity probes use a high-tech TFPC (Thin-Film Polymer Capacitance) humidity sensor, that provides rapid response and high accuracy. The probes are precalibrated at the factory. Several different versions are available for all application needs.
Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance. Unplug the instruments from power supply before replacing the fuse or making any electrical connections. Hanna Instruments reserves the right to modify the design, construction and appearance of its products without advance notice.
