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.

4 GETTING STARTED (continued)

5 CONNECTING YOUR PROBE

SEPARATE GAUGES ONLY

1 Rotate the probe plug to align the pins.

2 Screw in the collar - clockwise.

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.



•

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.

en-5

† The  softkey will appear when the “ X “ changes to a number.

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

the stored foil thicknesses - simplifying and

considerably speeding up the calibration

process

 “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.

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.
