C. DATA HOLD
This meter automaticallyholds the last
temperature reading onthe LCD for
five seconds afterthe ON/HOLD key is
released. No extrakey presses are
necessary to freezethe displayed

Holding the meterby its handle,point
the IR Sensortoward the object
whose temperature isto be measured.
The meter automaticallycompensates
for temperature deviationsfrom
ambient temperature. Keepin mind
that it willtake up to30 minutes to
adjust to wideambient temperature
changes.When low temperaturesare
to be measuredfollowed by high
temperature measurements,
some time (severalminutes) is required
after the low(and before thehigh)
temperature measurements aremade.
This is aresult of thecooling process
which must takeplace for theIR sensor

A flashing displayis the indicationthat
the battery voltagehas fallen intothe
critical region (6.5to 7.5 V).Reliable
readings can beobtained for several
hours after thefirst appearance ofthe
low battery indication.(Fig.G)
Open the BatteryCompartment and
remove the battery, then installa new
