GENERAL DESCRIPTION

HI 935005, HI 935005N, HI 935002 and HI 935009 are powerful
and flexible K-type thermocouple thermometers, which have been
designed using the latest microprocessor technology to provide reliable
and accurate measurements in a wide temperature range.

Standard features include K-type probes, waterproof casing, dual­level LCD, low battery detection, long battery life and two-year
warranty.

HI 935005 has been designed for laboratory and field use, while HI
935005N is suitable for high accuracy (meter and probe can be

calibrated in an ice bath at 0°C) or dimly lit areas (the backlight
feature can be easily activated through the keyboard).

HI 935002 is a two-channel thermometer, ideal for monitoring two
samples at once, while HI 935009 offers all the features of HI
935002 and more: calibration of meter and probe at 0°C, backlight,
user-selectable auto-off time period, and capability to store and recall
a reading.

OPERATIONAL GUIDE

To switch the instrument ON, press the ON/OFF key.
The thermometer will carry out a self diagnostic test routine, the LCD
will show all segments for a few seconds (or as long as ON/OFF is
held), followed by the percentage indication of the remaining battery
life.

HOLD mode.
Note: Although the display is frozen, internally the meter continues

measuring and updating Hi/Lo and relative values.

In HI 935009 only, the held value is also stored in non-volatile
memory and can be recalled by pressing (ALT+) MR key. While the
MR key is held, the "HOLD" tag lights up and the meter displays the
stored value; when the MR key is released, after 1 second the meter
returns to normal measurement mode.

The thermometer then enters normal measurement mode.
If a temperature probe is plugged in, the meter displays the
measured temperature.
If no probe is plugged in, or if the reading is
over-range, the display shows flashing dashes.
If a measurement is slightly over the range
of the meter specifications, the display will
flash the closest full-scale value.
To switch the meter OFF, press the ON/OFF key.

°C/°F SELECTION

Measurements can be displayed in either degrees Celsius or Fahren­heit. The meter is factory set to °C scale; to change the scale, press
°C/°F key or (ALT+) °C/°F keys,

HI 935005 / 5005N

HI 935009

or set the switch located in the battery compartment (HI 935002 only,
see figure on page 10).

HOLD and MR FUNCTIONS

The HOLD function is activated by pressing
the HOLD key.
The measured temperature is held on the
display until HOLD is pressed again. The
"HOLD" tag blinks on the display while in

HIGH/LOW TEMPERATURES

The maximum and minimum tempera­tures are continuously monitored and
displayed on the lower portion of the LCD.

Note: When the reading goes over-range

or the probe is removed, the Hi and
Lo values display dashes until cleared.

CLEAR FUNCTION

Upon pressing the CLR key, the High/Low values may be cleared at
any time during measurement and the current reading is assigned to
the highest and lowest temperature values for the displayed channel
only.

AUTO SHUT-OFF (HI 935005 and HI 935009)

To save battery life, the HI 935005 and HI 935009 models are
provided with an auto-off feature, which switches the instrument off
after a certain period of nonuse.

The delay time can be changed by the user (8 minutes, 60 minutes,
or disabled).
To access this feature, the HI 935005 is provided with an internal
button located in the battery compartment (see figure on page 10).
Unscrew the 4 screws on the back of the meter and select the desired
auto-off time period by pressing the button and viewing the value on
the LCD. Re-attach the back making sure that the gasket is in place
and tighten the 4 screws to ensure a watertight seal.

HI 935009 allows the user to select the auto-off time period through
the front keyboard; press (ALT+) AOFF to enter the mode, then set
the desired auto shut-off interval (8 min, 60 min, or disabled) with
the ALT key; release all buttons, wait a few seconds and the meter
will return to normal measurement mode.

2-CHANNEL MODELS (HI 935002 and HI 935009)

HI 935002 and HI 935009 models can monitor two samples through
two independent temperature channels (probes).

The display will show the actual, Hi and Lo (or T1 and T2) values of
the selected channel (T1, T2 or T1-T2). The corresponding tags will
light up to inform the user.

To select the desired channel, use the T1/T2 key.

BACKLIGHT FEATURE (HI 935005N and HI 935009)

HI 935005N and HI 935009 models are provided with a Backlight
feature, which can be easily activated through the keyboard by
pressing the BL key or (ALT+) BL keys.

HI 935005N

HI 935009

Note: The backlight automatically shuts off after approximately 1

minute with no buttons pressed.

BATTERY COMPARTMENT

The 2-channel models are also provided with the DISP function, which
allows the user to select the information to be displayed.

• While in T1 or T2, pressing DISP will switch the display between
standard and relative measurement modes.
In the standard mode, the main body of the LCD shows the
current temperature while the lower portion displays the Hi/Lo
limits for that channel.
When the meter enters relative mode, the current temperature for
that channel is set as the reference temperature. Pressing CLR will
also set the reference to the current temperature.

In relative mode, the main body of the LCD shows the difference
from the reference temperature. The lower portion displays the
current temperature for the selected channel.

• While in T1-T2, pressing DISP will switch between 3 displays:

Note: Pressing T1/T2 to change the channel will not alter the

information chosen to be displayed for each channel (DISP).

Note: Relative mode can not be entered if dashes are shown in the

main portion of the LCD.

BATTERY REPLACEMENTUSER CALIBRATION

The HI 935005N and HI 935009 models can be calibrated at 0°C by
using an ice bath.

• Prepare an ice bath with approximately equal volumes of distilled
water and chopped ice made from distilled water.

• Immerse the temperature probe in the center of the ice bath,
taking care not to touch the ice with the probe tip.

• Ensure that the meter is measuring a temperature within ±3°C.

• To enter the Calibration mode, press and hold the CAL button for
about 5 seconds.

• The CAL tag turns on to indicate that
the Calibration mode has been entered.

Note: If the measurement is outside the

±3°C window, the meter does not
enter Calibration mode.

• When the meter reaches the stability condition, which is detected
when the measurement remains within ±0.2°C for 5 seconds,
the calibration is accepted and the reading becomes 0°C (32°F).

• The meter then automatically returns to normal mode.

Note: To exit the Calibration mode at any time, press the CAL key.
Note: User calibration cannot be entered in relative or in T1-T2 mode.
Note: User calibration is only performed on the current channel

displayed (T1 or T2).

When the battery level is below 10%, a warning
symbol will blink on the LCD to indicate a low
battery condition.
If the battery level is low enough to cause erroneous readings, the
Battery Error Prevention System (BEPS) turns the meter off.
Immediately replace the batteries with new ones.
The batteries are accessed by separating the front and the back
halves of the meter: unscrew the 4 screws on the back of the meter
and carefully replace the three batteries located in the battery
compartment, while paying attention to their polarity. Reattach the
back making sure that the gasket is in place and tighten the 4
screws to ensure a watertight seal.
Battery replacement must only take place in a non-hazardous area
using 1.5V AA (IEC LR6) alkaline batteries.

FACTORY RECALIBRATION

All Hanna thermometers have been accurately pre-calibrated at the
factory.

It is generally recommended to have all thermometers recalibrated at
least once a year.

For an accurate recalibration, contact your nearest Hanna Customer
Service Center.

Recommendations for Users

Before using these products, make sure that they are entirely suitable for the
environment in which they are used.

Operation of these instruments in residential area could cause unacceptable inter­ferences to radio and TV equipments, requiring the operator to take all necessary
steps to correct interferences.

Any variation introduced by the user to the supplied equipment may degrade the
instruments' EMC performance.

To avoid electrical shock, do not use these instruments when voltages at the mea­surement surface exceed 24VAC or 60 VDC.

To avoid damages or burns, do not perform any measurement in microwave ovens.

Note: To clean the meters, do not use aggressive detergents. It is

recommended to use water.
