Note: When the reading goes over-range or the probe is removed,

the Hi and Lo values display dashes until cleared.

CLEAR FUNCTION (not for HI 93530 and HI 93530N)

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.

°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 the °C/°F key,

or set the °C/°F switch located in the battery compartment (HI 93532
and HI 93532N only, see figure on page 12).

AUTO SHUT-OFF

To save battery life, these meters are provided with an auto-off
feature, which switches the instrument off after 60 minutes of nonuse.

To disable this feature, all models (except HI 93531R & HI 93532R)
are provided with an internal switch located in the battery compart­ment (see figure on page 14).

HI 93531R and HI 93532R allow the user to disable the auto-off
feature through the front keyboard; press (ALT+) AOFF to enter the
mode, then set the desired option (auto-off after 8 or 60 minutes, or
disabled) with the ALT key; release all buttons, wait a few seconds
and the meter will return to normal measurement mode.

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.

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 reading is
over-range, the display shows flashing dashes.

If a measurement is slightly over the range
of the meter specifications, the display flashes
the closest full-scale value.
To switch the meter OFF, press the ON/OFF key.

Note: The meters are provided with an acoustic signal feature activated

when buttons are pressed, which can be disabled using a switch
located in the battery compartment (see figure on page 12).

HOLD FUNCTION

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

measuring and updating Hi/Lo values (not for HI 93530 and
HI 93530N).

HIGH/LOW TEMPERATURES
(not for HI 93530 and HI 93530N)

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

1514

DISP FUNCTION (HI 93531R and HI 93532R)

These models are also provided with the DISP function, which allows
the user to select the information to be displayed.

• While in T1 (or T2, HI 93532R only), pressing DISP switches the

display between normal, relative and average measurement modes.

In the normal 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 "REL" tag lights up

and 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.

When average mode is entered, the "AVG" tag lights up and the

current value is set as the new beginning value. The average can
be reset by pressing CLR while in the average mode.
In average mode, the main body of the LCD shows the average
temperature, while the lower portion displays the current tem­perature for the selected channel.

The average mode will calculate the average for a period of up to
24 hours. If a different mode is selected for that channel, the
average will no longer calculate and the value will be lost.
At the end of the 24 hour period, the "AVG" tag will blink to
indicate that sampling has stopped, and the displayed value is
the last average calculated.
If a probe is removed or over-range is reached while in average
mode, the display shows flashing dashes and blinking "AVG" tag.

BACKLIGHT FEATURE
(not for HI 93530, HI 93531 and HI 93532)

The backlight feature can be easily activated through the keyboard
by pressing the BL (or ALT+BL) key.

Note: The backlight automatically shuts off after approximately 1

minute with no buttons pressed.

BATTERY COMPARTMENT

See "Battery replacement" section for back cover removal/installation.

2-CHANNEL MODELS (HI 93532, HI 93532N & HI 93532R)

HI 93532, HI 93532N and HI 93532R models can monitor two
samples through two independent temperature channels (probes).

The display will show the actual, Hi and Lo 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.

1716

The average value is lost and will not restore even if the condition
restores. To start the average cycle again, either press CLR or re­enter the average mode.

• While in T1-T2 (HI 93532R only), pressing DISP will switch

between 4 displays:

Note: Pressing T1/T2 (HI 93532R only) to change the channel will not

alter the information chosen to be displayed for each channel
(DISP). For example, if T1 is in average mode, the average will
continue to be calculated even if the user press T1/T2 to see T2.

Note: Relative/average modes cannot be entered if dashes are shown

on the primary LCD.

Note: The auto-off time is disabled whenever a channel is set to

average mode.

When the battery level is below 5%, the battery 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 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.

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 24 Vac or 60 Vdc. To avoid damages or burns,
do not perform any measurement in microwave ovens.

USER CALIBRATION

(Not for HI 93530, HI 93531 and HI 93532 models)
The meters 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 T1-T2 mode.
Note: User calibration is only performed on the current channel

displayed (T1 or T2).
