5.Measuring Procedure
5.1 Press the"POWER" key to start the gauge The gauge will restore the state
of last operation itself. The gauge will display "Fe / 0um"or"NFe / 0um" , if you want
change the state of "Fe or NFe"press the"ZERO"key and the "POWER" key at the
same time, and then release "POWER" key firstly, 2 seconds later release the
"ZERO" key, the translation of "Fe or Nfe" finished.
5.2 Place the probe on the substrate or an uncoated standard steadily. Press
the "ZERO" key and "CAL0 OK" will be on the Display before lifting the probe. If
pressing the "ZERO" key but the probe is not placed on the substrate or an uncoated
standard, the zero adjustment is invalid.
5.3 Place the probe onto a coating layer to be measured. The reading on the
Display is the thickness of the coating layer.
5.4 To take the next measurement, just lift the probe to more than 1
centimeter and then repeat the step 5.3.
5.5 If suspecting the accuracy of measurement , you should calibrate the
gauge before taking the measurements. For the calibration procedures, please refer
to the calibration part 6.
5.6 The gauge will power itself off about 20 seconts after the last operation. It
can not be switched off by pressing the "POWER" key.
5.7 Pressing the "um/mil" key can change the measurement unit um or mil.
6.Calibration
6.1 Zero adjustment
Zero calibration for 'Fe' and 'NFe' should be carried out separately. Take the iron
substrate if 'Fe' on the Display and take the aluminium substrate if 'NFe' on the
Display. Place the probe on the substrate steadily. Press the "ZERO" key and "CAL0
OK" will be on the Display before lifting the probe. If pressing the "ZERO" key but the
probe is not placed on the substrate or an uncoated standard, the zero adjustment is
invalid.
6.2 Select an appropriate calibration foil according to your measurement
range.
6.3 Place the standard foil selected onto the substrate or the uncoated
standard.
6.4 Place the probe mildly onto the standard foil and lift. The reading on the
display is the value measured. The displayed reading can be corrected by pressing
the plus key or minus key while the probe is away from the substrate or the measure
body.
6.5 Repeat step 6.4 until the result is correct.
7.Battery Replacement
7.1 It is necessary to replace the battery, when the display reading changes
darkly.
7.2 Slide the Battery Cover away from the gauge and remove the batteries.
7.3 Install the batteries (2*1.5V) correctly into the case.
7.4 If the gauge will not to be used for a long time, remove batteries.
