4.1 ENSURING YOUR GAUGE HAS THE LATEST FIRMWARE &
UPGRADING YOUR GAUGE
To ensure that your gauge has the most up-to-date gauge firmware,
allowing you to benefit from the latest features and functionality, we
®
recommend that the gauge is connected to ElcoMaster on a regular
basis and before first use.
Simply connect the gauge via USB to an internet connected computer
®
running ElcoMaster using the ‘Connect Gauge’ feature. If a later
version of the gauge firmware is available, ‘Update Gauge’ will be
displayed to the right of the gauge details. Click ‘Update Gauge’ to
install the latest firmware.

6 TAKING A READING
1 Hold the probe by its sleeve.
2 To take a reading, bring the probe down onto the surface whilst
holding it perpendicular.
3 For subsequent readings, lift the probe off and then replace it on
to the coated surface.
DO
•
Hold the probe by the probe sleeve.
•
Gently place the probe onto the surface.
•
Allow the sleeve to make contact with the surface - to improve
accuracy.

† The softkey will appear when the “ X “ changes to a number.
R
6 TAKING A READING (continued)
DO NOT
•
Drag the probe over the coated surface.
•
Bang the probe down hard onto the surface.
•
Allow the probe to hover over the surface as this could result in
a false reading.
The display will dim if inactive for more than 15 seconds and will go ‘black’ if
inactive for the period defined in Menu/Setup/Screen Settings/Screen Timeout.
Either press any key, or tap the gauge to awaken it.
The gauge will switch off automatically after 5 minutes of inactivity.
- - - indicates reading outside range of probe.
7 CALIBRATING THE GAUGE
1 Press the Cal softkey.
2 For alternative calibration methods,
select Cal/Cal Method.
3 Select Calibrate and follow the on-
screen instructions.
4 When prompted place the probe on
the centre of the foil(s).
Foils can be stacked.
Not all calibration methods are available for all gauge types see 9 Calibration
Methods.

PIN.
CALIBRATION
METHOD
MODEL
DESCRIPTION
Zero
B, S, T
A one point calibration - ideal for smooth
surfaces, simply place the probe on the
uncoated substrate and the gauge will
automatically calibrate
Smooth
B, S, T
A two point calibration - the user selects a
suitable calibration foil and a smooth,
uncoated substrate (zero)
Rough/ 2 Point
B, S, T
The ideal calibration method for rough or
profiled substrates, using two foils of known
thickness - one above, another below the
target dry film thickness
Zero Offset
S, T
Calibration method for measurement when
the substrate profile/ roughness is unknown,
or not accessible. A user defined offset value
is applied to the measurement reading

Ideal for repetitive inspections. The user
stores known calibration foil thicknesses into
the gauge. When calibrating the user is
prompted to calibrate the gauge and the
gauge automatically adjusts the readings to
the stored foil thicknesses - simplifying and
considerably speeding up the calibration
process

To select the measurement mode, press Menu/Setup/Measurement Mode.
“Auto Repeat Mode” and “Scan Mode” are only available with an Elcometer 456
Ultra/Scan Probe. For further information contact Elcometer or visit
www.elcometer.com.
10.2 NAVSEA MODE
Displays the reading to the nearest 1mil (1µm) above 10mils (254µm)
and 0.1mil (0.1µm) below 10mils (254µm).
To select NAVSEA mode, press Menu/Setup/NAVSEA or Batch/New
Batch/NAVSEA.
11 BATCHING (MODEL S & T)
1 To use the Batching memory facility, press the Batch softkey.
2 Select “New Batch” or “Open Existing Batch” to add readings.
3 Copy and review batch data.
4 Select “Edit Batch” to rename, clear readings from or delete a
batch.
5 Fixed Batch Size allows users to pre-define the number of
readings to be stored in a batch. Once all readings have been
taken the gauge automatically opens a new batch with a link
to the original batch name. For Example NewBatch_1 becomes
NewBatch_2, NewBatch_3, etc.
Save each reading into memory or store the average of a pre-defined number of
readings using the Counted Average function.
