Storage and Handling
This instrument contains precision optics and electronics. You should avoid knocking or dropping
the device as the resulting impact could cause serious damage.
In some circumstances the optical components in the instrument could become misted due to
temperature change. It is recommended that the instrument is not used until it has stabilised to
ambient temperature.
Ensure that the instrument is not exposed to moisture, chemicals or to any corrosive vapours.
Do not interfere or place any objects inside the measuring aperture as damage to the measuring
system could occur.
The instrument housing and screen are normally resistant to a variety of solvents however it is not
possible to guarantee resistance to all chemicals therefore the surfaces of the instrument should
only be cleaned using a soft, moist cloth.
Prevent exposure of the instrument to direct sunlight for prolonged periods and to continuous
humidity and condensation.

About the Rhopoint IQ
The Rhopoint IQ is an advanced measuring instrument used to quantify the quality of surface appearance.
Unlike a standard glossmeter, the IQ has the unique capability of measuring and detecting quality problems
caused by microscopic texture in the surface that cause haze and orange-peel effects which lead to poor
Distinctness of Image (DOI),
These factors can seriously affect the visual impact and reflective quality of many coated, painted and
polished surfaces. By measuring the quality of the reflected image, it accurately profiles how light is reflected
from a surface.
The instrument uses a standard optical configuration at 60° and 85° to measure the gloss of matt and semi-
gloss finishes.
However, at 20° the IQ uses a diode array to measure the distribution of the reflected light at +/- 7.25° from
the specular angle of reflection in steps of 0.02832°.
This technology allows the instrument to calculate Gloss, Haze, DOI, RIQ and RSpec providing the user with a
complete analysis of the reflective quality of the surface.
Definitions of each of the parameters measured by the IQ can be found in the section “Appearance Theory”
detailed later in this manual.

Power
The Rhopoint IQ is powered by an integrated high capacity lithium ion cell.
Fully charged the instrument will operate continuously for >17 Hours or >20,000 readings.
A mains powered USB charger is provided with the unit. This will fully charge the unit when connected to the
unit’s USB input (6) in up to 9 hours.
Alternatively, the instrument can be powered and charged using the USB cable attached to any compatible
USB host (e.g. laptop etc.), Please note that charging from a USB host such as a laptop may take longer due
to the lower current available.
USB Connectivity
Three functions are available when the Rhopoint IQ is connected to a computer using the USB cable supplied.
Access Files – Allows access to measurement and configuration files on the instrument. The instrument
appears as a USB drive named IQ-METER. When selected the display on the instrument shows a USB memory
key as shown below.
USB Remote Control - Allows control of the IQ remotely by sending ASCII commands from a computer or PLC.
In this mode the instrument displays “REMOTE CONTROL ACTIVE” on the main measurement screen.
Battery Charge Only – Allows USB charging of the instrument – all instrument functions are available
however do not operate the instrument whilst it is connected via USB and/or charging.

Switching the Instrument on
To switch the Rhopoint IQ on, press the On / Off button located near the USB socket.
The instrument will display the IQ logo and then the Home screen displaying measurement parameters
according to the instruments default settings or those previously configured.
Similarly, the instrument can be powered off (dependent on configuration – see Instrument Setup) by pressing
the On/Off button for three seconds.
