5 Operation and handling ZGM 1120
The following paragraph guides through how gloss should be measured with a ZGM 1130.
Beside this the following notes shall be considered:
Proper measurements are only possible on even, clean and unscratched surfaces.
Always indicate the used measuring geometry for all measurements.
Measurements of different geometries can neither be compared nor converted into
another.
All the models of the ZGM 1130 series are equipped with an
automatic
adaptation of the
measuring range
, which makes them capable of measuring even specimen in the extended
measuring range
with values between 200 and 2000 gloss units. This enables you to
measure even specimens with high reflectance like mirrors or metallic specimens.
5.1 Calibration
Before a series of measurements is being started the device should be calibrated. In order to
do a calibration follow the steps below:
Clean the calibration standard with a microfiber cleaning cloth.
Place the ZGM 1130 on the calibration standard and start the device.
Open the quick menu with a
single tip on the touch screen and select “Calibrate”
.
Double check the stated calibration values with the values on the bottom side of the
calibration standard. If they match proceed by pressing “Calibrate” or set
-up the correct
values by pressing the “Setup” button.
Now, the ZGM 1130 performs a calibration on every angle and shows a calibration
summary when finished.
Accept or cancel the calibration.
Beside the provided calibration standard any other standard with a known value and
appropriate size can be used for calibration.
5.2 Measuring procedure
The ZGM 1130 can be used as a standalone device or
in conjunction with the “GlossTools”
software and a PC.
No matter if the ZGM 1130 is used standalone or with “GlossTools” the specimen should be
larger than the measuring area of the device (see section 9).
The center of the device’s measuring area is marked in longitudinal
direction with
on its housing.
5.2.1 Using the ZGM 1130 standalone
If the ZGM 1130 is used without connection to a PC measurements are stored by default in
a measurement file. Please follow the steps below:
Create or select a measurement file in the archive menu (see section 4.8.1)
Chose a measurement mode in the quick menu (see section 4.8.4)
Chose the appropriate measuring geometry in the setup menu (see section 7)
Trigger measurements with the measurement button.
