GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

HI 9161, HI 9261 and HI 91610 are portable, microprocessor-based printing/logging thermohygrometers.

The housing is made of rugged, lightweight material, making them truly portable. HI 9261 has been specifically designed by Hanna Instruments for use in the food industry.

The meters come equipped with a large, easy-to-read LCD. Measurements can be performed with lab-grade precision in the field

as well as in the laboratory without compromising accuracy. For prolonged field and lab applications, these meters can be

connected to a 12VDC adapter. The interchangeable relative humidity probe contains both the sensor

and the electronic circuitry necessary to amplify the R.H. measurements. Another electronic circuit converts the signal sent by the probe into a digital readout in % Relative Humidity. The standard cable is 2 meters (7') long, and a 5 meter (16.5') version is also available.

Note: the RH probe sensor must never come into contact with water

or other liquids.

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. The internal software allocates memory space to store up to 8000 measurements. HI 91610 will transfer the data in seconds through the infrared lights with no need for a cable between the transmitter and the meter.

Two versions of each instrument are available:

• HI 9161C, HI 9261C and HI 91610C are thermohygrometers with temperature readings in Celsius;

• HI 9161F, HI 9261F and HI 91610F are thermohygrometers with temperature readings in Fahrenheit.

RELATIVE HUMIDITY MEASUREMENTS

Using the HI 9161, HI 9261 and HI 91610 thermohygrometers is simple. However, the recommendations below should always be followed.

• The sensor end of the humidity probe should be exposed to a current of air moving at 0.5 m (20") per second or more.

• In the absence of air movement, the response can be accelerated by moving the probe back and forth.

• The probe sensor must never come into contact with water or any other liquid. If this should happen, or if condensation causes drops to form on the surface of the humidity sensor, the instrument must be turned off until moisture has completely evaporated. In order to accelerate the evaporation process, the humidity sensor should be exposed to a current of air.

If you experience any problems in taking measurements, please contact your Dealer or the nearest Hanna Customer Service Center.

TEMPERATURE MEASUREMENTS

The HI 762L/2 temperature probe supplied with the HI 9161, HI 9261 and HI 91610 is a liquid/general purpose probe with 2 m

(6.6') cable. Simply plug the probe into the socket located on the top of the meter

(refer to Functional Description on pages 5 to 7). If it is necessary to monitor temperature continuously, keep the probe

attached to the meter at all times. To view either the RH% or temperature read-

ing on the display, press RANGE. The reading will appear without decimal digit when shown on the lower secondary display. The temperature range on the secondary display is from 0 to 99°F (or °C).

If the temperature exceeds this range "--" will appear indicating that the small portion of the display is unable to accommodate the reading.

RANGE

1110

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.

Hanna temperature probes are supplied pre-calibrated from the factory and are ready to use.

Available in four different handle colors to avoid cross contamination during testing, these completely interchangeable probes make it possible to switch from one to another without needing to recalibrate the meter (see pages 34-35 for a complete listing).

In order to keep accurate records of temperature, your monitoring equipment must be properly re-calibrated. Hanna Calibration Test Plugs provide a quick and easy way to test the meter's accuracy. If the reading differs by more than ±0.4°C (±0.8°F) from the Test Plug value, the unit is due for re-calibration and you should contact your Dealer or the nearest Hanna Customer Service Center.

See page 36 to choose the right Test Plug to suit your needs.

CALIBRATIONCALIBRATION

CALIBRATION

CALIBRATIONCALIBRATION

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.

You can also check the status of your thermohygrometer and perform a quick RH recalibration (with an accuracy of ±5%) by using the optional Hanna HI 7101

mini-calibration chamber.

The kit is composed of two thermally-isolated chambers, each one equipped with a cap and three bottles containing the appropriate precalibrated saturated salts to produce a

known RH value.

PREPARING THE CALIBRATION SOLUTIONS

• Pour approximately 26 cc of distilled water into a glass container.

26 cc

• Immerse this container into a bath of ice and water.

Li C

• Slowly add the contents of a HI 7111 bottle containing LiCl into the glass container while stirring gently.

• When the salts have dissolved completely, add all the content of the second bottle of HI 7111.

• Allow the solution to cool, and pour it into the chamber marked "RH11.1%", making sure that no residue remains on the walls of the glass container.

• Seal the chamber well when not in use, as the LiCl solution is extremely hygroscopic and tends to capture the humidity

TO CHANGE THE INK CARTRIDGE

When printouts become faint, it might be necessary to change the ink cartridge. Contact your dealer or the nearest Hanna Customer Service Center for this.

HI 9161, HI 9261 automatically diagnose a fault and inform the user by displaying an error code on the LCD.

Error codes are: PEr0, PEr1, PEr2 = Short circuit on the system, the meter should be

returned for repair (see Warranty). PEr3 = Printer mechanism fault - repair needed (see Warranty). PEr4 = Printer clutch jammed - reset the printer (see page 32). PEr9 = Printer jammed - reset the printer (see page 32).

are factory programmed to

(HI 91610 only)

Capacity: 8000 data samples which are divided into 16 pages. Capacity per Page: up to 500 data. Each time a new logging mode is entered, the meter automatically goes

to the next available page. Once all 16 pages are used up, the meter will overwrite the first lot. During logging, the meter automatically returns to the oldest page in the memory and if it contains data, it will overwrite it. In this case the first log will not correspond to the oldest set of data. It is recommended to periodically “clean” the memory. Save data into a PC if you need to keep a record and then disconnect the batteries for about 1 minute. If you do this, remember to reset the time and date, once the batteries have been reinserted again.

TO INSERT PAPER ROLL

HI 9161, HI 9261

To insert a new roll gently pull out the printer cover.

Take out the used paper cylinder.

Insert the paper edge in the printer slot and feed the paper through by pressing the PAPER key.

and HI 91610

use plain 38 mm wide paper rolls.

ATTENTION

Data is stored into memory until batteries are removed. If replacement of the batteries is needed and data is not to be lost, first plug in an external 12VDC power supply and then proceed with battery replacement as described on page 33. Only once batteries have been replaced, it is possible to unplug the power supply without losing the previously memorized data.

PAPER

3130

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.
