OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with
batteries.
Remove the back cover, unwrap the
batteries and install them while pay-
ing attention to their polarity.
Connect a K-type thermocouple probe to
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
percentage indication of the remain-
ing 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 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.
Note
: Although the display is frozen, internally the meter
continues measuring and updating Hi and Lo values.
BATTERY REPLACEMENT
HIGH/LOW TEMPERATURES
The maximum and minimum tem-
peratures 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 24VAC or 60VDC.
To avoid damage or burns, do not perform any measurement in microwave ovens.
CE DECLARATION OF CONFORMITY
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 nonhazard-
ous 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.
