3 GETTING STARTED
3.1 FITTING BATTERIES
Your gauge may be used with dry cell batteries or rechargeable
batteries. 3 x LR6 (AA) alkaline batteries are supplied in the kit.
When the battery voltage is low the entire display will start to
flash. When this occurs the batteries should be replaced.
To fit or replace batteries:
1.
Unscrew battery compartment cover.
2.
Referring to battery polarity instructions on rear of gauge,
insert batteries into gauge ensuring correct polarity.
3.
Replace battery compartment cover.
Remove the batteries from the gauge if it is to remain unused for
a long period of time. This will prevent damage to the gauge in
the event of malfunction of the batteries.
Note: Alkaline batteries must be disposed of carefully to avoid
environmental contamination. Please consult your local
environmental authority for information on disposal in your
region.
Do not dispose of any batteries in fire.
3.2 FITTING THE TRANSDUCER
To change the delay line, unscrew the end of the transducer and apply couplant to the connecting
end of the delay line before screwing together.
The transducer transmits and receives ultrasonic sound waves that the
gauge uses to calculate the thickness of the material being measured.
The transducer connects to the gauge via the attached cable, and single
coaxial connectors.
Transducers are supplied with two replaceable delay lines, 6.35 mm (1/4")
and 12.7 mm (1/2"). The 12.7 mm (1/2") is suitable for most applications
and measures steel up to 25 mm. Generally, it should be used to measure
thicker materials. It will also dampen the signal of noisy materials, providing
better accuracy.
The 6.35 mm (1/4") delay line provides more signal strength and may allow
you to measure tough-to-penetrate materials.
Information can be found on the Elcometer NDT Knowledge Centre on www.elcometerndt.com.
3.3 SWITCHING ON/OFF
To switch on or off, press the on/off key
.
The gauge will switch off automatically after 5 minutes of inactivity.
4 THE MENUS
Your gauge has two menu systems:
•
Full menu - displays all the functions and settings of the gauge (see also page 28).
•
Hot menu - displays a sub-set of functions and settings related to taking measurements.
