GENERAL DESCRIPTION

FUNCTIONAL DESCRIPTION HI 9161

HI 9161 and HI 91610 are advanced portable, printing, thermohygrometers.

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. HI 91610 combines the high accuracy and portability of HI 9161

with extensive printing and logging features and an infrared RS232 data transfer system.

In addition to supplying the user with RH and temperature at the touch of a button, it also provides datalogging facilities that store information for transfer to a PC or for retrieval and/or printing at a later date.

Sophisticated software allocates up to 8000 readings to maximize available space, regardless of what the logging interval is.

The HI 9200 infrared transmitter is also available as an optional accessory.

HI 70604/5, RH probe with a 5 m (16.5’) cable is also available for special applications.

Both models are available in two versions, for °C or °F readings:

• HI 9161C and HI 91610C are thermo-hygrometers with temperature readings in Celsius

• HI 9161F and HI 91610F are thermo-hygrometers with temperature readings in Fahrenheit.

Each meter is supplied complete with four 1.5V AA batteries. Unscrew and remove the back cover, unwrap the batteries and install them while paying attention to their polarity (see "Battery Replacement" section for details).

Connect the RH probe to the DIN socket on the top of the meter and fasten the threaded ring tightly. Connect the temperature probe to the appropriate connector. The temperature probe can be used independently to take temperature measurements, or in conjunction with the RH probe.

If no probe is connected, "----" will appear on the LCD.

To switch the HI 9161 on, press ON/OFF.

To switch the HI 91610 on, press RANGE.

To save battery life, the display is automatically switched off after 5 minutes of non-use. However, when in recording/logging mode, the meter will continue to monitor RH and temperature.

To reactivate the display, press RANGE.

OPERATIONAL GUIDE

RELATIVE HUMIDITY MEASUREMENTS

Operations with the HI 9161 and HI 91610 are very simple.

• For accurate measurements, the RH sensor 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.

• The probe sensor must never come into contact with water or any other liquid. If this happens, 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. To accelerate the evaporation process, expose the humidity sensor to a current of air.

For any problem in taking measurements, please contact your dealer or the nearest HANNA Customer Service Center.

SETTING DATE, TIME & PRINTING INTERVAL WITH HI 9161

When the instrument is turned on, the display shows the TIME.

Press the INTV and RANGE keys simultaneously. The display will then show the date previously memorized with the year blinking (shown as the last 2 digits of the year, e.g. 95=1995).

TEMPERATURE MEASUREMENTS

The HI 762L/2 temperature probe supplied with theinstrument 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. If continuous monitoring of temperature is needed, 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 secondary display. The temperature range on the secondary display goes from 0 to 99°C (or °F).

If the temperature exceeds this range, "--" will appear indicating that the secondary display is unable to show the reading.

If no probe or test plug is connected, the meter will 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 application requirements. HANNA HI 762 probe series use highly sensitive thermistor sensors to provide great accuracy and fast response (see "Accessories" section for a complete list).

RANGE

When the correct year is selected, press the RANGE key once and the month will start blinking.

RANGE

Select the correct month by pressing the UP or DOWN keys.

UP DOWN

Press RANGE and the day will start blinking.

RANGE

Use the UP or DOWN keys to select the correct day. The day will still blink.
