Practice
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 Calibrating
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 v
alues 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.
