Selecting MODES
Press the MODE button to display one of the fol-
lowing:
Average Temperature (AVG)
During a temperature reading,
the average temperature read
during the scan is displayed.
Maximum Temperature (MAX)
During a temperature reading,
the highest temperature read
during the scan is displayed.
Minimum Temperature (MIN)
During a temperature reading,
the lowest temperature read
during the scan is displayed.
Humidity (HUM)-2277-20 only
During a temperature reading,
the relative humidity (RH%) read
during the scan is displayed.
The relative humidity is taken at
the meter, not at the point of the
temperature reading.
Dew Point Temperature
(DEW)
During a temperature reading,
the dew point read during the
scan is displayed. The dew
point is taken at the meter, not
at the point of the temperature
reading.
OPERATION
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
Scanning Object IR Temperature
1. Pull and hold the trigger for at least 2 seconds
and scan the surface temperature of an object.
A laser pointer indicates the center of the circular
area being scanned.
NOTE: The object should be larger than the spot
being scanned. If not, readings will be affected.
See Distance To Spot for necessary object size.
Distance to Spot 40:1
At 120" (10') away,
spot is 3" in diameter
At 80" away,
spot is 2" in diameter
At 40" away,
spot is 1" in diameter
—— Center of Spot
– – – Laser pointer (approx. 3/4" above center of spot)
Spot size at distance indicated
2. As you continue to hold
the trigger, the icon
is
displayed along with the sur-
face temperature (primary
measurement) along with
any selected mode readings
(secondary measurement).
3. Release the trigger. HOLD
is displayed until the screen
shuts off in about seven sec-
onds.
NOTE: A quick change in tem-
perature affects the unit’s read-
ings. Allow unit to reach ambient
temperature before use.
ASSEMBLY
WARNING Recharge only with the

Avoid Exposure: Laser Radiation Is
Emitted From This Aperture
To reduce the risk of injury, user must
read operator’s manual.
WARNING Never connect the Tem-
perature Probe to an energized circuit.
Contact Temperature Measurement with K-Type
Probe
Only use K-type Temperature Probes with this
meter.
1. Insert the probe. The unit
detects a connection of a K-
type probe and displays the
contact temperature (CON)
as the secondary measure-
ment.
2 The display will continue
to update the contact tem-
perature (CON) while the
temperature probe reaches
thermal equilibrium with the
object being measured. The
display will shut off after
about 20 minutes.
3. To take an IR reading while
using the K-type probe, pull
the trigger. The IR reading is displayed as the
primary measurement.
4 If set, the alarm will alert for the contact tem-
perature when the sensor probe is installed.
