3.1 On/Off Switch
To turn the gauge on, press the ON/OFF Switch briefly
(see photo on page 3). Press and hold the ON/OFF Switch
for 2 seconds to turn the power off.
Note: The gauge will power off automatically after
90 seconds of non-use.
3.2 Selection of Measuring Units
1. Make sure the gauge is switched OFF.
2. Press and hold the ZERO and STATS keys simultaneously
3. While continuing to hold down the ZERO and STATS
keys, turn the power ON.
3.3 Manually setting the measuring mode
DCFN-3000EZ Only
In some cases, especially with varnish applied to zinc on steel,
it is advisable to manually set the measuring mode—F mode
(Ferrous) for measurements on steel/iron, N mode
(Non-ferrous) for measurements on non-ferrous metals.
Setting the measurement mode
1. Turn the gauge on by pressing the ON/OFF switch.
2. Press the ZERO and STATS keys simultaneously to
change the measuring mode. Each time the keys are
pressed the mode will change.
The display will show the mode selected (see photo,
page 4) using the following abbreviations:
