Operations Manual for the
HardyTest D400!
!
!
1. Introduction !
!
Welcome to SaluTrons HardyTest D400 operations manual. The D400 was developed to do
fast, comfortable and easy measurements in the field of hardness testing. !
!
The following are included in the delivery: !
!
Measuring device: The D400 gauge for hardness tests. From chapter 2
on all functions of the D400 !
are explained. !
!
Hydraulic impactor: With the hydraulic impactor the actual
measurements are executed. For all necessary information
about the hydraulic impactor see chapter 7. !
!
Wires: Included is one USB cable for transferring the
measured data from the gauge to the PC and a wire for connecting the gauge with
the hydraulic impactor. You connect the wire by inserting the end with the three
spikes to the hydraulic impactor and the other end to the round input at the top of
the gauge. Note that there is a red dot at the input as well as at the end of the wire.
To plug in the wire correctly both dots have to match with each other. !
!
TKM Link: This is the software for transferring the measured data from the gauge to
your Windows PC. You can find all relevant information in chapter 8.!
!
Test block: The test block (steel) is used to control the right
calibration of the gauge. It has an hardness of roundabout 800
HLD. If the standard deviation should be higher then +/- 6 HLD
contact our service department. !
!
Paste: The included paste serves for connecting a test coupon with
a weight below 5 kg to a heavier object. See chapter 7.2 for details. !
!
Brush: Cleaning brush for the hydraulic impactor. See chapter 6.2. !

2. Technical Specification!
!
!
2.1 Principal of Measurement !
!
The HardyTest D400 is a instrument for hardness testing which works on the basis of the HL/
HLD principal. This method was first introduced in 1978 by Ing. D. Leeb. The idea is that an
impactor falls on another objects and rebounds. The harder the object is the greater the
rebound velocity is. Therefore the value HLD is calculated by the quotient of the rebound
velocity and the impact velocity multiplied with 1000.!
!
!
!
!
!
!
!
If we consider a certain set of materials like steel, aluminum etc., the HLD value with which
the above-mentioned pieces were measured represents a direct hardness value and, as
such, can be used for a further comparison with other hardness values (Brinell, Vickers,
Rockwell, Shore, etc.).!
!
Note: The HardyTest D400 only works with hydraulic impactors of the type D. !

4. Start up Screen!
!
When turning on the gauge following screen will appear. This is the main screen in which all
measurements are executed. !
4.1 Adjust Measurement Parameters!
!
To executed a metering correctly it is crucial to adjust the measurement settings depending
on the situation. By pressing the right screen key (Chang) once it is possible to adjust the
material to the test piece´material. By pressing that button twice it is possible to adjust the
unit (HLD, HRC etc). If the button is pressed thrice the measurement angle can be adjusted.
That means, if one holds the hydraulic impactor e.g. horizontal, while measuring, 180 degree
(↔) must be adjusted. If not the result will be wrong. Alternatively these settings may be
adjusted also trough pressing the Menu button and then going on Settings .!

5. Main Menu!
!
To get access to the Main Menu you have to press the Menu button while on the Start up
screen. !
Here you will find following options. !
5.1 Settings!
!
In the Settings section you can also adjusted the material, unit and angle for the
measurement like explained in 4.1.!
!
5.1.1 Material!
!
In this respective section the user hast to adjust the specific material of the test piece he will
gauge. To navigate through the menu use the left & mid screen key. By pressing Enter the
material will be selected and you come back to the Menu Settings. You can adjust that
settings also directly from the Start up screen. See 4.1 for that.!
!
5.1.2 Units!
!
In this section the user has to adjust the unit he wants to have his results in. It is important to
consider that not every material may be measured in every unit. For example: If one wants to
measure the hardness of bronze he can only choose between the units Leeb (HLD) & Brinell
(HB). However if one wants to measure the hardness of brass he may choose between
Leeb, Brinell & Rockwell B (HRB). At the end of this section you can find a detailed table
regarding this problem. !
!
Page ? of ?14 22

HardyTest D400
Note: The unit Leeb will be always shown as an reference to prevent following problem.!
If a metering shows a result of e.g. 500 HLD and the user has adjusted Rockwell C (HRC) as
his main unit the screen will show following. !
The problem is that there is no value in HRC until 510 HLD (20.00 HRC = 510 HLD). That
means that a hardness below 510 HLD can´t be shown in HRC. 

!
5.2 Alarms!
!
The HardyTest D400 offers the feature to set so called alarms. That means that the user may
set an value for the minimum hardness and for the maximum hardness of his measured
material. If the function is activated and the result should be below the minimum or above the
maximum, the D400 signals that the result is out of the tolerance limit by showing an
exclamation mark on the display. !
!
Note: Should the user change the unit in which he measures he will also have to adjust the
alarm settings towards that. The adjustments are always made in the currently selected unit. !
!
5.3 Memory !
!
This is an alternative way to get access to the memory settings mentioned in 4.3.!
!

6. Maintenance !
!
The HardyTest D400 in general doesn't need to be maintained to much. Nevertheless there
are to thinks to consider.!
!
6.1 Batteries!
!
The gauge operates with an 9 Volt block battery. If the battery status should be low obviously
the battery has to be changed. To do that it is necessary to open the stand and to remove the
screw at the middle backside of the gauge. !
!
Note: Batteries are hazardous waste and are therefore to dispose properly. !
!
In order to optimize the operation of the device, it is recommended:!
!
-Not to mix new batteries with old ones.!
!
-Use alkaline batteries.!
!
-Change batteries whenever indicated by the instrument.!
!
-If the device won´t be used for a long period of time, it is recommendable to remove
the batteries from the battery compartment to avoid damage due to battery aging.!
!
6.2 Maintenance of the hydraulic impactor!
!
In order to ensure a long life performance of the hydraulic impactor we advice you to clean it
from time to time. The only things you need is the in the delivery included brush and some fat
free solvent. You need to rub the solvent on the brush and insert it as indicated below. !
Caution: The user should never lubricate any part of the device!!
!
It is also crucial to check the right calibration with the test block (800 HLD; steel) provided. If
the standard deviation should be higher then +/- 6 HLD the impactor is probably used up. In
this case contact our service department.!

7. Correct Measuring !
!
After the adjustment of the measurement parameters (material, unit, angle) you may directly
start with the metering. Don´t forget to check the right calibration from time to time as
indicated in the last paragraph of 6.2. !
!
7.1 Preparation of Test Piece!
!
The test piece should be clean. If the piece has some kind of surface treatment, this must be
scraped off in a minimum area of 20 to 30 mm2 until obtaining a roughness of up to 10
micrometer.!
!
7.2 Execution of Measurement !
!
Take the hydraulic impactor and load the impact body compressing it against the test piece
as illustrated below.!
!
Hold the device with both hands to avoid movement at the moment of reading. Press the
button on the upper end of the hydraulic impactor. In that moment, the test will be made.
Simultaneously, the value of hardness obtained in the selected scale will be shown. If manual
saving is adjusted you may wish to save the result by pressing ENTER. !
