4.8.4 Modes
The ZGM 1130 supports three different measure modes.
Standard and Sequence mode are used to trigger one
measurement at a time. Whereas Scan mode measures
continuously with high speed as long as the measure button
is pressed. This enables to measure an average value over
a much larger area than just the measuring area itself.
In Standard mode, only single measurements are taken
and the statistic values are reset when the mode has been changed or the same mode has
been chosen again.
In Sequence mode, the number of single measurements which should be made and lead to
an average value can be predetermined. The statistic values are reset after this predefined
number of single measurements, when the mode has been changed or the same mode has
been chosen again.
In Scan mode, the ZGM 1130 measures with high speed as long as the measuring button is
pressed. All single measurements completed during that time lead to one single average
value which will be added to the statistic display. Treated as one measurement. The statistic
values are reset when the mode has been changed or the same mode has been chosen
again.

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.

18. May 2021 © Copyright 2021, PROCEQ SA 16
5.2.2 Using the ZGM 1130 with “GlossTools”
In order to use the ZGM 1130 connect the device via USB to a PC. When the device is
connected chose “Measure” from the pop-up menu on the device to establish a
connection with “GlossTools”. While connected measurements can be triggered
with the measurement button of the device or by software. For a detailed
explanation of the “GlossTools” software refer to the software instruction manual.
