2.4 Temperature Measurements
2.4.1 General Operation
CAUTION... SHOCK HAZARD
DO NOT TOUCH THE INSTRUMENT TO
ELECTRICAL CONDUCTORS*
The DX™ measures temperature very quickly. To obtain an accurate
measurement, it is only necessary to touch the surface for a fraction
of a second.
For exact surface temperature measurements that are NIST traceable,
use the following procedure:
1.
Press and hold the MEASURE button.
2.
The display will briefly show [8888].
3.
Touch the nosepiece to the target surface.
4.
The display may or may not change, but the "beeping" sound will
indicate that measurements are being made.
5.
Record the temperature from the display.
6.
Release the MEASURE button. The last reading will remain
locked on the display for 10 seconds after releasing the button.
*If the target is electrical equipment, Exergen manufactures the Model
E Microscanner instruments for safe and convenient inspection of
electrical equipment. Contact Exergen for more information on the
Model E line of instruments and electrical inspection. If the surface
is metallic, be sure to mark it as described in the Measurement Tips
section in Chapter Three.
2.4.2 Temperature Measurement of Moving Targets
To measure moving targets that are not possible to touch, use the fol-
lowing procedure:
1.
Press and hold the MEASURE button.
2.
The display will briefly show [8888].
3.
Bring the nosepiece as close as possible to the target, preferably
within 1/32 inch (1 mm). **
4.
The display may or may not change, but the "beeping" sound will
indicate that measurements are being made.
5.
Record the temperature from the display.
6.
Release the MEASURE button. The last reading will remain
locked on the display for 10 seconds after releasing the button.
