1. General technical information
1.1 Construction of the instrument
The DIAVITE Compact VH is constructed either for one-handed operation with tracer incorporated in
the main unit or alternatively equipped with adapter and measuring cable for use as a very versatile
surface roughness meter.
When using for one-handed operation, the traverse unit (picture
1) with inserted roughness tracer is plugged directly to the socket
of the instrument housing. The instrument is suitable to effect
roughness measurements on even or round surfaces.
DIAVITE Compact VH as one-handed picture 1
operated instrument
The DIAVITE Compact VHF is supplied with an adapter, which, in place of the traverse unit, is
connected directly with the instrument socket, and an extension cable for measuring directly with the
smaller traverse unit. This enables free measurements, to reach badly accessible measuring spots,
and to effect measurements by means of a measuring support as well, unavoidable for measuring with
skidless tracers.
For many measuring applications, the adapter (picture 2) is
needed, connected with the cable leading to the traverse unit.
This way, measurements with special tracers and measuring
support are possible. As an option, this adapter with extension
cable to the traverse unit can also be supplied for DIAVITE
Compact VH.

The traverse unit and the adapter, held by two fixing balls in the instrument, must by no means
be inserted obliquely, as this could cause damage of the plug contacts.

1.3 Connections
Mains adapter USB
Under the cover at the narrow rear of the instrument
there are connections for the electrical mains supply
and an USB port for connection to a computer.
1.3.1 Mains adapter 90 – 264 VAC / 50 – 60 cycles
The mains adapter connection serves for the electric power supply of the instrument. If this adapter is
connected, the instrument is provided with electric current during operation and simultaneously, the
batteries are being charged – if necessary.
Only the original mains adapter may be used for this purpose. It is specially designed for use with
many international electric mains tensions (for admitted values refer to: Technical data, ‘mains
adapter’, page 2).
Suitable plugs for corresponding national standards are available from the agent or from electro-
technical stores.
1.3.2 Interface USB
The interface USB serves for the direct connection to a computer. This must be equipped with a
suitable software (option) for receiving the data.

1.4 Connection of the tracer
Attention: No measuring is possible without connected tracer and traverse unit.
Remove the supporting shoe by using the enclosed hexagon key (type VH) or by
means of the knurled nut (type VHF).
Traverse unit VH or VHF Supporting shoe
Insert the tracer into the traverse unit as shown in the picture. The two red points must match each
other. If manual measurements are to be effected, remount the supporting shoe to the traverse unit
again.
Warning: By no means the tracer is to be inserted forcefully; it must be held with the utmost
care at its largest diameter!
The position of the supporting shoe is reached correctly when the work piece is supported on its whole
length by the traversing unit with supporting shoe. If the measuring area is too small, the bottom
surfaces of traversing unit and the supporting shoe must be on the same level.
Warning: When measuring together with the support, please make sure that the tracer is not
bent by lowering it too deeply onto the work piece. There is no guarantee for bent tracers.
1.5 Traverse unit
The number of the instrument and the number of the traverse unit must be identically!
Prior to starting the instrument, connect the traverse unit to the measuring unit with the 6-core
connection cable. This cable provides the traverse unit with the necessary electric tension and
transmits the measuring signal.
The cable plugs for the connection cable have an integrated locking. The cable must, therefore, be
held at the plugs only when being inserted or removed, as otherwise the connection between cable
and plug could become damaged.
1.6 Switch-on/off of the instrument
The instrument can be switched-on with any of the keys. It can be operated with the incorporated
rechargeable batteries or by means of the electric mains adapter directly from the mains (see 2.6
electric power supply).
If for some time no key of the instrument had been pressed, the instrument would switch-off
automatically. The duration of time for automatic switch-off can be set (see 3.1 Menu – Config –
Switch-off). A manual switch-off is not possible.

1.7 Calibration
The DIAVITE COMPACT has an automatic calibration, which is at disposal in the menu 3.1 -
‘configuration - calibration’ (page 10). In order to avoid faulty measurements, it is absolutely
indispensable to check the perfect function of the instrument before starting the first daily
application, as well as in regular periods of time. This can be effected the easiest way with a
roughness specimen 3.00 µm Ra, alternatively with another reference specimen, the exact
value of which is known.
When changing a tracer, the instrument has to be recalibrated also. The deviations between the
various tracers should be rather small, normally, but could cause anyhow faulty measuring
results. The recalibration of the instrument runs automatically. Put the reference specimen
onto the supporting shoe of the traverse unit or effect this procedure employing a measuring
support. The settings must be correct.
1. Press any button, after some seconds, the instrument is ready for operation
2. Press the button , you are in the mode ‘Menu: Tracer’
3. Press the button
until the indication ‘Menu: Config.’ appears
4. Press the button
once, in the display appears ‘Config.: Calibration’
5. Press the button , the indication ‘3.00’ appears
For calibration, the cutoff 0.8 mm will be set automatically!
6. Press the button
or , if you do not employ the original roughness standard
7. Press the button once, for starting the calibration
8. It takes approximately one minute to effect the calibration (4 measurements)
9. At the end of the calibration procedure, the current measuring value Ra is indicated. In course,
the instrument is in the ‘main menu’ again
10. Press the button
, you are again in the measuring mode
1.8 Keyboard
The DIAVITE COMPACT is a surface roughness meter easy to operate and for the safe operation of
which only few introduction is necessary. The instrument can be set according to the operator’s needs
using the menu functions. The keys are provided with pictographs for the following functions:

2. Operation
2.1 Measuring
2.1.1 Start measuring operation
The area to be measured on the work piece must be properly cleaned in order to avoid that the
tracer is getting dirty. If the roughness is measured manually, the tracer is laid onto the work piece and
held steadily. At the lowest margin of the display, the position of the feeler can be controlled with the
arrow (↑). The ideal setting is reached when this sign appears in the centre of the display: →←. After
pressing the start key, the measuring procedure is effected automatically. In course, the measuring
values can be read on the LCD-display and printed out.
Pressing any key can interrupt a current measuring operation and bring the tracer to a halt. Actuate
the start button once more, to bring the tracer to its starting position again.
If the tracer is not in correct position, the measuring procedure can be released nevertheless!
2.1.2 Maximum measuring value
The maximum amplitude of the diamond stylus is 200 µm. If this is exceeded, there will be no
signal of faulty measurement. However, such high measuring values will always be indicated by the
arrow (↑), which means that the measuring results could be faulty.
2.1.3 Special tracers (probes)
Complementary to the standard tracer, there are a number of special tracers at disposal. These are
constructed to solve specific measuring problems and can be used only together with the measuring
stand.
2.1.2 Maximum measuring value
The maximum amplitude of the diamond stylus is 200 µm. If this is exceeded, there will be no
signal of faulty measurement. However, such high measuring values will always be indicated by the
arrow (↑), which means that the measuring results could be faulty.
2.1.3 Special tracers (probes)
Complementary to the standard tracer, there are a number of special tracers at disposal. These are
constructed to solve specific measuring problems and can be used only together with the measuring
stand.
Tracers without skid can be used only with the traverse unit VHF
The traverse unit must be set parallel to the measured surface.
When lowering the tracer onto the work piece, the 0-point of the feeler must be adjusted
exactly. The arrow indicates the direction, to which the tracer must be moved:
TasterTaster
Taster
Taster
Taster
On the display, the arrow is situated on the lef
t
margin and shows downwards
Carefully lower the tracer, until the pointer moves
from the left margin towards the centre.
If the correct zero point is reached, two arrows
appear in the middle of the indicator screen.
Push the key ‘M’ and start the measuring
operation.
If the sensor is set too deep, the arrow appears on
the right half of the display and shows
upwards. The tracer must be set in a
higher position
ATTENTION, the tracer might be damaged!

2.1.4 Calibration
The DIAVITE DH-7 has an automatic calibration, which is at disposal in the menu ‘configuration’ (page
10). In order to avoid faulty measurements, it is absolutely indispensable to check the perfect function of the
instrument before starting the first daily application, as well as in regular periods of time. This can be effected the
easiest way by measuring the surface of a roughness specimen. The measured roughness value is compared
then with the nominal value indicated on it and – if necessary – a new calibration of the instrument must be
effected.
If a tracer is exchanged, the instrument has to be recalibrated. The deviations between the various
tracers should be rather small normally, but could anyhow cause faulty measuring results. The
instrument can be recalibrated automatically. The settings must be correctly.
You will find a detailed description of calibration on page 6 (point 1.7)
The calibration is always effected with cutoff 0.8 mm (lt=4.8 mm)
2.1.5 Remote control
The traverse unit is equipped with a multifunctional blue remote control button to switch the instrument
on, or – if already switched on – to release the measuring operation. When employing the DIAVITE as
one-handed operated instrument or with a measuring stand, this button is inactive.
2.2 Selection of the traversing length
The cutoff filters serve to eliminate the long wavy parts of the roughness (waviness). They correspond
to the usual standards (BSI, ASA, DIN) and are coupled with the traversing length.
Measuring length Lt
mm
Traversing length lm
mm
Cutoff Lc
mm
1.5 1.25 0.25
4.8 4.0 0.8
15.0 12.5 2.5
The cutoff should be selected according to the standards valid in your country. If no indications are
given in drawings, the cutoff 0.8 mm is normally used.
2.3 Tolerance
In this menu any tolerance value for Ra, Rt od Rz can be set. If the value set is exceeded after a
measurement, the indication begins to flash, and in the corner top right appears – if a tolerance is set
– the sign ↓
↓↓
↓.
2.4 Memory functions
The instrument has a memory function which is switched-on and –off in the captioned menu. With that
function, it is possible to hold up to 15 measuring values, which can be transferred over the serial
interface to a suitable PC, or printed out with the PC. As an acknowledgement, the roughness values
are taken over to the memory.
If the memory function is active, an “M” appears in the display.
2.5 Key lock
The instrument is equipped with a key lock preventing any settings being changed by mistake during
measuring procedure. It is effective for the buttons lt (length of traverse), and lc (cutoff).
After having set the parameters, push the button and then again the button as long until the
indication ‘locked’ appears. In order to suspend the key lock, repeat the described procedure, until the
indication “unprotected” appears.

2.6 Electric power supply
At the narrow side there is a sliding cover which can be drawn downwards (1.3 ‘Electric power
supply’). Behind, you will find a two-core socket for the power supply, serving to charge the batteries
for operation independently from the electric mains. The instrument should be operated only with the
specially adapted original charger/mains adapter, in order to avoid damages.
To charge the batteries, connect the mains adapter with the DIAVITE COMPACT and switch-on the
instrument. A battery symbol in the display shows that the batteries are being charged. The indication
will extinguish as soon as the batteries are completely recharged. Charging takes approximately ten
hours. You may continue to work with DIAVITE COMPACT during the period of recharge.
The charging procedure must not be interrupted!
Important remarks:
The incorporated accumulators (Lithium-Manganese rechargeable batteries) are designed for a long
live if treated correctly:
If the instrument has not been in use for a longer time, the accumulators must be charged at least
once each month.
If the capacity of the batteries is exhausted, the display indicates ‘Low Bat’. No more measuring
operations can be effected. The batteries must be recharged without delay.
From new or perfectly treated, completely charged batteries, approx. 400 measuring operations could
be expected, depending from the selected length of traverse.
2.7 Maintenance
The DIAVITE COMPACT does not need any maintenance except the charging of the rechargeable
batteries (see 2.6).
Under no circumstances, the traversing unit and the tracers must be treated with oil or
detergent. If the housing of the instrument is dirty, it may be cleaned with a mild cleaning liquid or with
soap.

4.2 Malfunctions
The DIAVITE COMPACT has been constructed for workshop use. The tracers are, however, very
delicate and susceptible to damages. They should not be exposed to mechanical strain. If, when
putting a tracer with skid onto a flat surface, the green control LED does not start to flash up, the tracer
could be damaged. If possible, check the instrument with a second tracer or send the complete
instrument to the dealer for a check.
4.3 Repairs
Repairs are to be effected by the manufacturer only.
Upon written request, a repair cost estimate will be submitted. The necessary efforts for controlling,
partially dismantling of parts, inspection time as well as an adequate share for administration effort,
and transport costs, must be paid by the customer in any case, even if the estimate of cost is rejected
by the customer.
80% of the repairs concern the standard tracer SH (dirt, oil, break of diamond point and suspension). It
is recommended to buy a spare standard tracer.
4.4 Guarantee
The guarantee is valid for one year after factory dispatch and is applicable to damage caused by parts
of proved insufficient quality. The guarantee does not cover damages of the diamond tip and the
rechargeable batteries, nor malfunctions due to mechanical damages, such as break of suspension,
bending or breaking of parts (which are delicate due to their nature of construction), nor damages
caused by non-observation of the working instructions, or damages caused by insufficient packing for
transport back to the factory. Parts to be replaced must be sent back to the factory.
