Operation
Meter Power
Install two 'AAA' 1.5 V batteries into the rear battery compartment. Press the power button
to switch the meter ON. The display will switch ON. If the display does not switch ON, install or
replace the batteries. When powering up, please keep the meter at least 10cm (4") from metal
objects. Replace the batteries when the battery status icon appears low, the meter will give
inaccurate readings if the battery voltage falls very low.
Measurements
Before each measurement session please perform a Zero Calibration as described later in this
User Guide.
Practice with the film and zero reference metal substrates to learn how the meter operates
before moving to a professional application. The heavier metal substrate is the ferrous
(magnetic) zero substrate (Fe) and the lighter metal substrate (Al) is the non‐ferrous (non‐
magnetic) zero substrate. In Auto mode, the meter automatically senses ferrous and non‐ferrous
substrates.
1. Place a reference film (250µm, for example) on the ferrous substrate (FE).
2. Power the meter on by pressing the power button.
3. Place the spring‐loaded meter sensor against the reference film.
4. The meter will emit an audible tone indicating that the measurement has been taken.
5. The LCD will show the reading at the center of the display area.
6. For a typical display see the Display description diagram.
Automatic Power OFF
In order to conserve battery life, the meter will automatically turn off after approximately 3
minutes. To defeat this feature, use the programming menu detailed in the next section (menu
parameter AUTO POWER OFF under SET).
