Hanna Instruments HI 9060 - Manual (Page 2)

OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with
batteries.
Remove the back cover, unwrap the
batteries and install them while paying
attention to their polarity.
Connect the temperature probe to the
connector on the top of the meter.
To switch on, press the ON/OFF key on
the front of the meter.
If the meter does not come on, make
sure that the batteries are correctly
installed.
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 per-
centage 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 flash-
ing dashes.
If a measurement is slightly over the range of the meter
specifications, the display flashes the closest full-scale value.
To switch the thermometer OFF, press the ON/OFF key.
MEASURING SCALE (°C/°F)
The instrument is factory set to the °C scale, but measurements can
be performed in either the Celsius or Fahrenheit scale.
Press the °C/°F button to select the desired
scale.
HOLD MODE
The HOLD function is activated by pressing
the HOLD key.
The measured temperature is held on the
display until HOLD is pressed again.
The "H" tag blinks on the display to
indicate the HOLD mode.
BATTERY REPLACEMENT
The instrument is powered by four 1.5 V alkaline batteries
and is provided with the Battery Error Prevention System
(BEPS), which turns the unit off when a low battery signal is
detected.
When the remaining battery level is
less than 10%, a warning symbol
blinks on the display to indicate a low
battery condition.
It is recommended to replace the batteries as soon as the low
battery condition is detected.
Battery replacement must only take place in a nonhazardous
area using four 1.5V alkaline batteries.
In order to replace rundown batteries, simply remove the two
screws on the rear cover of the instrument and replace the
four batteries with new ones paying attention to the correct
polarity.
Reattach the cover and tighten the two screws.
All Hanna thermometers have been accurately pre-calibrated
at the factory.
It is recommended to have all thermometers recalibrated at
least once a year. For an accurate annual recalibration,
contact your nearest Hanna Service Center.
Hanna Accuracy Test Plugs provide a quick and easy way to
test the meter's accuracy by simply connecting these Test Plugs
to the probe connector of the meter. If the reading differs by
more than ±0.4°C (±0.8°F) from the Test Plug value, the
meter is due for recalibration. Choose the Test Plug closest to
your measurement range to best suit your needs:
HI 765-18C Calibration test key, –18.0°C
HI 765000C Calibration test key, 0.0°C
HI 765070C Calibration test key, 70.0°C
HI 765-004F Calibration test key, –0.4°F
HI 765032F Calibration test key, 32.0°F
HI 765158F Calibration test key, 158.0°F
FACTORY RECALIBRATION
Note: Although the display is frozen, internally the meter
continues measuring and updating Hi and Lo values.
HIGH/LOW TEMPERATURES
The maximum and minimum tempera-
tures are continuously monitored and
displayed in the lower portion of the
LCD.
Note: When reading goes over-range, the Hi and Lo values
display dashes until cleared.
CLEAR FUNCTION
Upon pressing the CLEAR key, the
current reading is assigned to the
highest and lowest temperature val-
ues. The High/Low values may be
cleared at any time during measure-
ment.
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 areas could cause unacceptable interference to radio and
TV equipment, requiring the operator to take all necessary steps to correct interference.
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 voltage at the measurement surface
exceeds 24 Vac or 60 Vdc.
To avoid damage or burns, do not perform any measurement in microwave ovens.
TEMPERATURE PROBES & ACCESSORIES
Hanna offers a wide range of probes to meet your needs with
air, liquid, penetration and surface measurements.
All Hanna temperature probes are pre-calibrated at the
factory and ready-to-use. These interchangeable probes make
it possible to switch from one probe to another without
requiring recalibration.
Hanna probes are also available in different handle colors to
avoid cross contamination during testing.
