Thank you for purchasing the Wahl DHS235XEL non-
contact infrared thermometer. To measure a temperature,
simply point the unit at the object, pull the trigger and
read the display. Releasing the trigger will put the unit into
hold mode, which will display the captured reading for
approximately 6 seconds before powering off. Make sure
the target area is larger than the unit’s spot size. For large
target objects assure you are within target distance.
The DHS235XEL features a wide temperature range,
and high D:S (Distance to Spot) ratio, allowing the user
to measure high temperature objects from a safe
distance.
High DS ratio.
Adjustable emissivity from 0.1 to 1.00 in 0.01 steps.
Ultra low power consumption in shutdown mode.

Read the following safety information carefully before
attempting to operate or service the instrument. Only
qualified personnel should perform repairs or service not
covered in this manual.
2-1 Warning
DO NOT submerge the instrument in water
This product is not designed for use in medical
evaluations.
This product is intended for use in industrial, scientific
and educational purposes only.
Dangerous, refer to this manual before using
the meter.
CE Certification.
This instrument conforms to the following standards:
EN61326: Electrical equipment for measurement,
control and laboratory use.
IEC61000-4-2: Electrostatic discharge immunity test.
IEC61000-4-3: Radiated, radio-frequency,
electromagnetic field immunity test.
IEC61000-4-8: Power frequency magnetic field
immunity test.
Tests were conducted using a frequency range of 80-
1000MHz with the instrument in three orientations. The
average error for the three orientations is ±0.5°C
(±1.0°F) at 3V/m throughout the spectrum. However,
between 781-1000MHz at 3V/m, the instrument may not
meet its stated accuracy.

Do not point laser directly at eye. Use
caution around reflective surfaces. Keep out of
reach of children.
